You've been approved as a Walmart supplier — congratulations. Now comes the technical requirement that stops many vendors in their tracks: EDI compliance.
Walmart processes over 260 million customer transactions weekly across 10,000+ locations. To handle that volume, they require all suppliers to exchange business documents electronically using specific EDI transaction sets, formats, and timelines.
Miss a deadline, send the wrong EDI document structure, or fail testing — and your products don't ship. Worse, you'll face chargebacks that can run thousands of dollars per violation.
Here's everything you need to know about Walmart's EDI requirements in 2026, including required transactions, testing process, common rejection errors, and how to get compliant fast.
Walmart doesn't approve every brand that wants to be a supplier. They operate on a massive scale and, like all smart businesses, want to minimize risks as much as possible.To learn more about Walmart's requirements and the application process, visit their official Suppliers page. Below you can get a better idea of their basic requirements.
To get approved as a new Walmart supplier you will need to be EDI capable, and you will need to use AS2 to send EDI transactions between your company and Walmart. Application Standard 2 (AS2) is the most usual method of transmitting EDI data over the internet.AS2 is the benchmark for security and reliability for the Internet and cloud-based EDI systems, which is why Walmart requires vendors to use it.
As an approved supplier, you will need to be 100% in-sync with Walmart and provide specific data through a Global Data Synchronization Network (GDSN). Essentially, GDSN allows trading partners to share their business data with each other automatically.This gives Walmart confidence in their suppliers because as suppliers update their database, Walmart's database is automatically updated ㅡkeeping everyone informed in real-time.
To reduce shrinkage, Walmart requires suppliers to use source security tagging. This is the practice of applying disposable anti-theft labels during the manufacturing or distribution process. Tagging products with an authorized source tagging label certifies your products are legitimate.
Walmart is increasing the amount of locally-based products in their stores, and they only accept regional suppliers now. That means your startup or growing company has a better chance of getting your products in your local Walmart stores than ever before.
Walmart requires you to register with Dun & Bradsheet and have a D&B risk rating of less than 7. This D&B rating provides a quick indication of your company's creditworthiness, which helps Walmart identify profitable opportunities for risks and growth that could affect cash flow.
