UNFI EDI Requirements: The Complete 2026 Guide for Food & Beverage Brands

UNFI EDI Requirements: The Complete 2026 Guide for Food & Beverage Brands

Introduction: The UNFI Opportunity

UNFI (United Natural Foods, Inc.) is the largest distributor of natural, organic, and specialty foods in North America. With distribution to over 30,000 retail locations—including Whole Foods, Sprouts, Natural Grocers, and thousands of independent natural food stores—UNFI is the gateway to the natural products industry.

For emerging food and beverage brands, a UNFI partnership means immediate access to the retail channel that matters most: health-conscious consumers willing to pay premium prices for quality products.

But here's what many brands discover too late: UNFI's operational requirements are as demanding as any major retailer.

Unlike selling direct-to-consumer where you control the entire experience, UNFI relationships require precise coordination across ordering, shipping, invoicing, and compliance tracking. The brands that scale successfully with UNFI are those that treat EDI compliance as a core operational capability from day one.

This guide covers everything you need to achieve and maintain UNFI EDI compliance in 2026:

  • The complete list of required EDI documents
  • Step-by-step setup process from vendor agreement to go-live
  • UNFI Supplier Portal navigation and best practices
  • GS1 and barcode requirements specific to distribution
  • ASN specifications that prevent chargebacks
  • Fill rate and compliance standards
  • Common errors and how to avoid them

Whether you're an emerging natural foods brand landing your first UNFI account or an established supplier optimizing operations, this guide will help you succeed as a UNFI vendor.

UNFI EDI Requirements Overview

What is UNFI EDI?

UNFI EDI (Electronic Data Interchange) is UNFI's standardized system for exchanging business documents with suppliers electronically. Purchase orders, advance ship notices, invoices, and other documents flow through structured data formats that integrate directly with UNFI's warehouse and distribution systems.

Key Point: UNFI strongly prefers EDI-capable suppliers. While manual order processing exists for very small suppliers, EDI capability significantly improves your fill rate metrics, reduces errors, and positions you for growth. As order volume increases, EDI becomes effectively mandatory.

Why UNFI EDI Matters for Natural Brands

UNFI operates differently than retailers like Walmart or Target:

Distribution Model

  • UNFI doesn't sell products directly to consumers
  • They distribute your products to thousands of retail accounts
  • Your success depends on UNFI efficiently moving product to retailers
  • EDI accuracy directly impacts store-level availability

Velocity Requirements

  • Natural food retailers expect consistent product availability
  • Stockouts at distribution level cascade to retail stockouts
  • Fill rate failures can result in retailer deauthorizations
  • EDI accuracy is the foundation of reliable fulfillment

Scale of Operations

  • UNFI processes millions of cases weekly across 50+ distribution centers
  • Manual processes create bottlenecks and errors
  • EDI automation enables you to scale with UNFI growth
  • Brands without EDI hit operational ceilings quickly

UNFI EDI Standards and Protocols

UNFI uses the ANSI X12 EDI standard, consistent with most U.S. retailers and distributors. Specific requirements include:

  • Version: ANSI X12 4010/5010 (both versions supported)
  • Communication Protocol: AS2 (Applicability Statement 2) preferred; VAN connectivity supported
  • VAN Support: UNFI works with major Value Added Networks including SPS Commerce, TrueCommerce, and others
  • Testing: Required testing in UNFI's certification environment before production

UNFI Divisions and EDI Variations

UNFI operates multiple divisions, each with slightly different operational requirements:

UNFI Conventional

  • Traditional grocery and natural food distribution
  • Standard EDI document set
  • Largest division by volume

UNFI Specialty (formerly Haddon House)

  • Specialty and gourmet food distribution
  • Similar EDI requirements with some variation
  • Separate vendor setup process

UNFI Fresh

  • Perishable and refrigerated products
  • Tighter timing requirements
  • Additional temperature documentation

UNFI Canada

  • Canadian distribution operations
  • Similar EDI standards with currency adjustments
  • Separate trading partner setup

Required EDI Documents for UNFI Suppliers

UNFI suppliers must support a core set of EDI transaction types. Here's the complete breakdown:

Core Required Documents

EDI 850 - Purchase Order

The foundational document for every UNFI transaction. When UNFI needs inventory, they send an 850.

  • Contains: Item numbers (UNFI item codes and UPC), quantities, costs, ship-to DC locations, requested delivery dates
  • Frequency: Can be daily for high-velocity items, weekly for slower movers
  • Response: Required acknowledgment via EDI 855 (if enabled) or ship/invoice flow

EDI 855 - Purchase Order Acknowledgment

Your confirmation that you received the purchase order and can fulfill it.

  • Purpose: Confirms receipt, validates pricing, flags any fulfillment issues
  • Timing: Should be sent within 24 hours of receiving the 850
  • Content: Acknowledges line items, quantities, and pricing
  • Note: Some UNFI programs make this optional; check your specific requirements

EDI 856 - Advance Ship Notice (ASN)

Critical for efficient receiving at UNFI distribution centers.

  • Contains: Shipment details, case-level content, pallet configuration, carrier info
  • Timing: Must be sent BEFORE shipment arrives at UNFI DC
  • Accuracy: Must match physical shipment exactly—discrepancies trigger receiving delays
  • Importance: ASN accuracy directly impacts your supplier scorecard

EDI 810 - Invoice

Your bill to UNFI for goods shipped.

  • Contains: Line items matching the shipment, quantities, costs, payment terms
  • Timing: Typically sent within 24 hours of shipment
  • Matching: Must reconcile with PO and ASN or payment holds occur

Additional Document Types

EDI 846 - Inventory Inquiry/Advice

  • Reports your current inventory availability to UNFI
  • Helps UNFI optimize replenishment orders
  • Increasingly important for demand planning programs

EDI 860 - Purchase Order Change Request

  • UNFI's modifications to original purchase orders
  • May include quantity changes, date adjustments, or cancellations
  • Requires response via EDI 865

EDI 865 - Purchase Order Change Acknowledgment

  • Your acceptance or rejection of UNFI's requested changes
  • Required response to any 860 received

EDI 812 - Credit/Debit Adjustment

  • Handles returns, allowances, and adjustments
  • Used for managing chargebacks and deductions

EDI 820 - Payment Order/Remittance Advice

UNFI EDI Setup Process: Step-by-Step

Setting up EDI with UNFI involves coordination between your company, your EDI provider, and UNFI's vendor systems. Here's the process:

Phase 1: Vendor Agreement and Onboarding

Step 1: Complete UNFI Vendor Application

Before EDI setup, you need to become an approved UNFI vendor:

  • Submit product information and pricing
  • Provide proof of insurance (typically $2M liability minimum)
  • Complete food safety documentation (if applicable)
  • Set up payment terms (typically Net 30)

Step 2: Receive Vendor Number

UNFI assigns a unique vendor number that identifies your company across all their systems. This number appears on every EDI transaction and is essential for setup.

Step 3: Access UNFI Supplier Portal

Register for UNFI's online vendor management system:

  • Company legal information
  • Tax documentation (W-9)
  • Banking details for ACH payment
  • Primary contacts for orders, shipping, and compliance

Phase 2: EDI Provider Selection and Configuration

Step 4: Select an EDI Provider

You have several options for UNFI EDI connectivity:

  1. Full-Service EDI Provider (Recommended for emerging brands)
  • Provider manages technical setup and maintenance
  • Pre-built UNFI mappings available
  • Faster implementation timeline
  • Ongoing support for changes
  1. VAN (Value Added Network)
  • Mailbox-based document routing
  • Works if you already have VAN connectivity
  • Additional fees per transaction
  • Good for multi-distributor suppliers
  1. Direct Connection (AS2)
  • Connect directly to UNFI's systems
  • Requires more technical resources
  • No per-document VAN fees
  • Best for high-volume suppliers

Russ Wallace, CEO & Co-founder of Freestyle, emphasizes the value of speed:

"As a startup, our biggest advantage is speed of execution. Having a partner, like Crstl, who shares that same advantage and acts quickly was incredibly valuable, especially when it allowed us to get EDI set up with UNFI sooner, which in turn allowed us to secure better payment terms."

Step 5: Configure Connection

Work with your EDI provider to establish connectivity:

  • Exchange trading partner IDs with UNFI
  • Configure AS2 certificates or VAN mailbox routing
  • Test connectivity before document mapping

Step 6: Build Document Mappings

Your EDI system must translate UNFI's formats to your internal systems:

  • Map UNFI item codes to your product database
  • Configure DC location codes (50+ distribution centers)
  • Set up unit of measure conversions (eaches, cases, pallets)
  • Define exception and error handling rules

Phase 3: Testing and Certification

Step 7: Submit Test Documents

UNFI requires testing before production transactions:

Test 855 (PO Acknowledgment)

  • Send acknowledgment for test POs
  • Verify format compliance
  • Confirm all required fields populated

Test 856 (ASN)

  • Create ASN with correct structure
  • Validate case/pallet identification
  • Verify shipment content accuracy

Test 810 (Invoice)

  • Submit invoice matching test PO
  • Verify pricing and quantity matching
  • Confirm required reference numbers

Step 8: Receive Certification Approval

Once all test documents pass validation:

  • UNFI enables production trading
  • You receive notification to begin live transactions
  • First orders are monitored for compliance

Phase 4: Go-Live and Optimization

Step 9: Process Live Orders

  • Monitor initial POs carefully
  • Verify ASN timing meets requirements
  • Confirm invoice reconciliation
  • Address any acknowledgment errors immediately

Step 10: Establish Ongoing Compliance Monitoring

  • Review supplier scorecard regularly
  • Track fill rate trends
  • Monitor for pricing discrepancies
  • Scale operations as order volume increases

GS1 and Barcode Requirements for UNFI

GS1 Company Prefix

Before shipping to UNFI, you need a GS1 Company Prefix—the foundation for all product identification.

What You Need:

  • GS1 US Company Prefix (obtained from GS1 US)
  • Ability to generate unique GTINs for each product
  • Capability to create SSCC codes for shipping containers (if palletizing)

Cost Structure:

  • Initial license fee: $250 (up to 10 products) to $10,500+ (100,000+ products)
  • Annual renewal: $50 to $2,100+ depending on prefix capacity

UPC/GTIN Requirements

UNFI requires GS1-compliant GTINs on all products:

Product-Level Barcodes

  • Consumer unit (each) must have unique GTIN-12 (UPC-A) or GTIN-13 (EAN)
  • Case pack must have unique GTIN-14 (ITF-14 barcode)
  • Each size, flavor, or variety requires separate GTIN
  • Inner packs (if applicable) need unique identification

UPC Quality Standards

  • Minimum barcode quality grade of C or higher
  • Proper quiet zones around barcode
  • Scannable at multiple angles
  • Consistent placement on packaging

Case Barcode Requirements

  • ITF-14 format for case identification
  • Scannable by UNFI warehouse systems

Silas Ang, Director of Operations at Immi, notes the importance of operational excellence:

"Crstl is exactly what I wanted and more. I would recommend them to any food & beverage brand at any stage. Their platform is easy to use and their customer service is terrific."

UNFI ASN Requirements (EDI 856)

The ASN is critical for efficient receiving at UNFI distribution centers. Accurate ASNs enable faster receiving, better inventory visibility, and higher supplier scores.

ASN Timing Requirements

When to Send:

  • ASN must be transmitted BEFORE shipment arrives at UNFI DC
  • UNFI uses ASN data to plan receiving labor and dock assignments
  • Late ASNs cause receiving delays and may impact your scorecard

Best Practices:

  • Send ASN within 30 minutes of carrier pickup
  • For LTL shipments, send before carrier's estimated delivery
  • Never send ASN after shipment has arrived

Why Timing Matters:

  • UNFI DCs receive hundreds of shipments daily
  • Pre-arrival ASN data enables efficient scheduling
  • Late or missing ASNs force manual receiving processes
  • Manual receiving is slower and more error-prone

ASN Structure for UNFI

UNFI's ASN requirements focus on shipment and case-level information:


Shipment Level

├── Order Level (PO reference)

│   └── Case/Carton Level

│       └── Item Level (contents of each case)


Levels Explained:

  • Shipment: Overall shipment information, carrier, dates
  • Order: Links to specific UNFI PO number
  • Case: Individual case identification
  • Item: Contents of each case by UPC and quantity

ASN Content Requirements

Header (Shipment) Level:

  • Shipment identification number
  • Ship date and estimated delivery date
  • Carrier name and tracking number (PRO number for LTL)
  • Bill of lading number
  • Ship-from location
  • Ship-to UNFI DC

Order Level:

  • UNFI PO number
  • PO date reference

Case Level:

  • Case identification (if using case-level tracking)
  • Case quantity
  • Case weight (if required)

Item Level:

  • UPC for each product
  • Quantity shipped
  • Unit of measure
  • UNFI item number (if available)

Common ASN Errors

Quantity Mismatch

  • ASN shows 100 cases, physical count is 95
  • Creates receiving discrepancy
  • Result: Potential short-pay on invoice

Missing PO Reference

  • ASN doesn't properly reference the PO number
  • DC cannot match shipment to order
  • Result: Receiving delays

Wrong Ship-To Location

  • ASN shows different DC than actual destination
  • Causes confusion in receiving
  • Result: Potential rerouting delays

Timing Issues

  • ASN sent after shipment arrives
  • DC already started manual receiving
  • Result: Duplicate data entry, potential errors

UNFI Fill Rate and Compliance Standards

Understanding Fill Rate

Fill rate is the single most important metric for UNFI suppliers. It measures your ability to ship what UNFI orders.

Fill Rate Calculation:

Fill Rate = (Cases Shipped / Cases Ordered) × 100


UNFI Fill Rate Expectations:

  • Target: 95%+ fill rate
  • Minimum acceptable: 90%
  • Below 90%: Risk of volume reduction or deauthorization

Why Fill Rate Matters

For UNFI:

  • They promise retailers reliable product availability
  • Low supplier fill rates create retail stockouts
  • Stockouts damage UNFI's retailer relationships
  • UNFI prioritizes high-fill-rate suppliers

For Your Brand:

  • High fill rate = more UNFI order volume
  • Low fill rate = reduced orders, lost shelf space
  • Consistent fill rate builds buyer trust
  • Fill rate impacts promotional opportunities

Fill Rate Improvement Strategies

Inventory Planning

  • Maintain safety stock for UNFI orders
  • Monitor UNFI DC inventory levels via portal
  • Plan production around UNFI order patterns
  • Communicate supply constraints early

Order Management

  • Process UNFI POs immediately upon receipt
  • Prioritize UNFI fulfillment during allocation
  • Ship complete orders when possible
  • Communicate partial shipment plans in advance

EDI Accuracy

  • Accurate 855s flag potential shortages early
  • Correct ASNs ensure proper receiving credit
  • Invoice accuracy prevents payment delays
  • Clean data = clean metrics

On-Time Delivery Requirements

Beyond fill rate, UNFI tracks on-time delivery performance:

Delivery Window:

  • Must arrive within the specified delivery window
  • Early arrivals may be refused (DC scheduling)
  • Late arrivals impact UNFI's distribution to retailers
  • Appointment compliance is critical for certain DCs

Carrier Coordination:

  • Use UNFI-approved carriers when specified
  • Coordinate appointments when required
  • Provide accurate tracking information
  • Communicate delays proactively

Supplier Scorecard

UNFI maintains a supplier scorecard that tracks:

  • Fill rate percentage
  • On-time delivery performance
  • ASN accuracy
  • Invoice accuracy
  • Quality issues and returns
  • Compliance with promotional commitments

Josh Lazenby, Senior Operations Manager at KitchenSupply, emphasizes partner support:

"The ability and willingness of Crstl to help is night and day compared to other providers. They're not just a vendor; they're genuinely invested in our success."

Common UNFI EDI Errors and Chargebacks

Understanding UNFI Deductions

UNFI deducts fees and adjustments directly from your payments. Understanding these helps you prevent them:

Types of Deductions:

Compliance Deductions

  • ASN errors and timing violations
  • Labeling non-compliance
  • Routing or delivery violations

Shortage Deductions

  • Quantity discrepancies between ASN and receipt
  • Missing cases in shipment
  • Damaged goods received

Promotional Deductions

  • MCB (Manufacturer Chargeback) for promotions

"Crstl delivers a product that makes traditional platforms look like a protection racket. As a fast-emerging brand, Crstl enables us to adapt and scale without viewing us as another pocket to pick."

UNFI vs Retail EDI: Key Differences

Distribution vs. Retail Model

Understanding the differences between distributor EDI (like UNFI) and retailer EDI (like Walmart or Target) helps you manage both relationships effectively.

UNFI (Distributor) Model:

  • UNFI is your customer (they buy from you)
  • UNFI sells to thousands of retailers
  • Your products go to UNFI DCs, then to retail stores
  • You don't control final retail placement
  • Fill rate directly impacts retailer availability

Retail Model:

  • Retailer is your direct customer
  • Products go directly to retailer DCs or stores
  • You may have more visibility into store-level performance
  • Chargebacks often more severe
  • More stringent compliance requirements

Key EDI Differences

Aspect UNFI (Distributor) Major Retailers
Order Frequency Regular replenishment cycles Variable, promotion-driven
Ship-To Locations ~50 UNFI DCs Hundreds of DCs/stores
ASN Complexity Case-level typically sufficient Often pallet/SSCC required
Chargeback Severity Moderate Often severe (Walmart, Target)
Compliance Strictness Important but flexible Very strict (OTIF, MABD)
Primary Metric Fill Rate OTIF / On-Time In-Full

Managing Both Relationships

If you sell to both UNFI and major retailers:

Separate Trading Partner Profiles

  • Maintain distinct EDI configurations for each
  • Different document mappings may be required
  • Test changes in isolation before production

Inventory Allocation Strategy

  • Prioritize based on relationship value and penalties
  • Consider retailer chargeback severity
  • Balance UNFI fill rate against retail compliance

Unified Visibility

  • Use EDI platform that supports multiple partners
  • Centralized order management across channels
  • Consistent data quality standards

Frequently Asked Questions

What are the basic UNFI EDI requirements?

UNFI requires suppliers to exchange documents electronically using ANSI X12 EDI standards. The core documents are: EDI 850 (Purchase Order received from UNFI), EDI 856 (Advance Ship Notice), and EDI 810 (Invoice). EDI 855 (PO Acknowledgment) is recommended but not always required. Suppliers can connect via AS2 protocol or through an approved VAN. All products require GS1-compliant UPCs for consumer units and ITF-14 barcodes for case identification.

How long does it take to set up UNFI EDI?

With traditional EDI providers, UNFI EDI setup typically takes 7-12 weeks from vendor approval to go-live. This includes provider onboarding (2-3 weeks), connection configuration (1-2 weeks), document mapping (2-4 weeks), and certification testing (2-3 weeks). Modern AI-powered EDI platforms can reduce this timeline to 1-2 weeks by using pre-built UNFI mappings and automated testing.

What is the cost of UNFI EDI?

UNFI EDI costs vary based on your provider and transaction volume. Traditional providers typically charge implementation fees ($1,000-5,000), monthly minimums ($300-800), and per-document fees ($0.15-0.50 per transaction). Modern AI-powered EDI platforms often offer flat monthly pricing ($500-1,500/month) without per-document fees. Additional costs include GS1 membership ($250-10,500/year depending on product count) and any ERP/WMS integration work.

What fill rate does UNFI expect from suppliers?

UNFI expects suppliers to maintain a fill rate of 95% or higher—meaning you ship at least 95% of the cases ordered. The minimum acceptable fill rate is typically 90%. Fill rates below 90% may result in reduced order volume, loss of promotional opportunities, or potential deauthorization. Fill rate is calculated as Cases Shipped divided by Cases Ordered, expressed as a percentage.

How does UNFI EDI differ from Walmart or Target EDI?

While the same ANSI X12 standards apply, key differences include: order frequency (UNFI has regular replenishment cycles vs. variable retail orders), ASN complexity (UNFI often accepts case-level vs. pallet/SSCC-18 required by retailers), chargeback severity (UNFI deductions are typically less punitive than Walmart/Target chargebacks), and primary metrics (UNFI focuses on fill rate vs. OTIF for retailers). Managing both requires separate EDI configurations.

Do I need EDI to sell to UNFI?

For small suppliers with limited order volume, UNFI may accept manual order processing. However, EDI capability is strongly preferred and becomes effectively mandatory as your volume grows. EDI improves order accuracy, reduces processing time, enables faster receiving at UNFI DCs, and positions you for growth. Most suppliers find that EDI investment pays off quickly through operational efficiency and improved supplier scorecard metrics.

How do I dispute UNFI deductions?

When you receive a deduction, first review the detail in the UNFI Supplier Portal to understand the reason code and evidence. Gather supporting documentation including proof of delivery, ASN transmission confirmation, and any photos. Submit your dispute through the portal's dispute system within the allowed timeframe. Track the dispute status and respond promptly to any UNFI requests for additional information. Document outcomes to improve your processes and prevent future deductions.

Can I use the same EDI setup for UNFI and other distributors?

While many distributors use similar ANSI X12 EDI standards, each has specific requirements for document content, timing, and structure. Your EDI provider should maintain separate trading partner profiles for each distributor (UNFI, KeHE, etc.) and retailer. If you already have EDI with retailers, adding UNFI typically requires new mapping work but can leverage your existing connection infrastructure. AI-powered EDI platforms with pre-built trading partner templates make multi-partner EDI much simpler.

Conclusion

UNFI EDI compliance is essential for food and beverage brands serious about scaling in the natural products channel. The brands that thrive with UNFI treat EDI not as administrative overhead but as a strategic capability that enables growth.

Key takeaways from this guide:

1. Understand UNFI's Distribution Model

Unlike retailers, UNFI distributes your products to thousands of stores. Your EDI accuracy directly impacts product availability across the natural products retail landscape. Fill rate is your most important metric.

2. Choose the Right EDI Infrastructure

Your EDI provider choice determines your speed to market and ongoing operational efficiency. AI-powered platforms offer faster onboarding, pre-built UNFI mappings, and built-in validation that prevents errors before they become deductions.

3. Prioritize Fill Rate

UNFI expects 95%+ fill rate. Plan inventory to support UNFI orders, process POs immediately, and communicate constraints early. High fill rates lead to more order volume and better buyer relationships.

4. Use the Supplier Portal Proactively

Don't wait for problems. Monitor your scorecard regularly. Track inventory positions at UNFI DCs. Catch deduction trends early and address root causes before they accumulate.

5. Build for Multi-Channel Growth

Many natural brands sell through both UNFI and direct retail relationships. Modern EDI infrastructure should support multiple trading partners with unified visibility and consistent data quality.

The brands winning with UNFI are those who view EDI compliance as a core operational capability—not a necessary evil. Modern, AI-powered EDI makes that capability accessible to emerging brands, not just enterprise suppliers with dedicated EDI teams.
