For entrepreneurs who want to sell on Walmart US, one of the most important steps is applying with the right documents. Walmart Marketplace doesn't just check basic information during seller approval — it also reviews company structure, tax records, identity verification, and payment infrastructure.
That makes "what documents do I need to open a Walmart seller account?" a critical question to answer before you ever submit an application.
According to Walmart's official sources, sellers applying to the US Marketplace must provide a business tax ID or business license number along with supporting documents that verify the company.
This article walks through the core documents you may need for a Walmart Marketplace application, and what to watch for before submitting.
1. Company Information and Company Documents
Walmart Marketplace evaluates incorporated businesses rather than individual sellers. So documents demonstrating the legal existence of your company matter during the application process.
Company information that may be required:
- Official company name
- Company type
- Country of incorporation
- Company registration number
- Company address
- Authorized person details
- Business activity
Your company can be a US-incorporated LLC, a UK Ltd, or a legally established business in another country Walmart accepts. What matters is that the company information is consistent with official documents.
Walmart's business verification guide states that company info must be entered exactly as it appears in IRS records or government-issued documents.
2. Tax ID or Business License Number
One of the most critical items in Walmart US Marketplace applications is the tax record. According to Walmart's official documentation, sellers applying to the US Marketplace are asked for a business tax ID or business license number.
For US-based companies this is generally known as the EIN (Employer Identification Number) — the company's identifier within the US tax system.
Tax information matters in the application because it:
- Enables legal verification of the company
- Is required for tax reporting
- Helps align payment infrastructure with company info
- Is used in Walmart's seller security checks
If the tax number or business license info is entered incorrectly, the application can stall or verification can fail.
3. Identity Verification Documents
In addition to business information, Walmart may also request authorized person verification. Walmart's official sources note that a personal ID copy may be required before applying.
Identity verification matters because it shows the person submitting the application is authorized to act on behalf of the company.
Information typically checked:
- Authorized person's name and surname
- Date of birth
- Identity document
- Address
- Connection to the company
The identity information used here must be consistent with the data on the application form.
4. Address Verification Information
In Walmart applications company address is an important verification field. Your company address must match the address on your official documents.
Even small differences in address information can create issues. For example, an address listed as "Street" on the official document but written in a different format on the application can create system matching problems.
Watch out for:
- Company address must match official documents
- Avoid PO boxes or low-trust address structures
- Country, city, and ZIP code must be entered correctly
- Address must align with payment account and company documents
Walmart's business verification process emphasizes that company info must match official records.
5. Payment Infrastructure Information
To sell on Walmart Marketplace, your payment method also needs to be set up. Walmart's official seller registration guide lists, as one of the steps in the application process, connecting the preferred third-party payment processor account to the Walmart Marketplace seller account.
At this stage, the payment account information must be consistent with your company information.
Watch out for:
- Payment account must be in the company's name
- Account holder info must align with company paperwork
- Currency and country information must be selected correctly
- Bank or payment provider details must be entered without errors
Inconsistencies in payment infrastructure can delay account activation.
6. Product and Category Information
In a Walmart Marketplace application, the products you plan to sell matter as well — not just company documents. Walmart may evaluate which categories sellers will sell in, whether the products comply with platform policies, and the seller's operational capability.
Helpful info to prepare before applying:
- Product categories to sell
- Product descriptions
- Brand information
- Supply chain information
- Inventory management plan
- Shipping and returns process
- Customer service plan
A professional, clear product plan helps the application come across as more trustworthy.
7. Customer Service and Store Information
As a Walmart Marketplace seller, listing products isn't enough on its own. Customer satisfaction, returns, shipping performance, and support quality also matter.
Information that may be required during the application or account setup:
- Store display name
- Customer service email address
- Business phone
- Returns policy
- Shipping settings
- Seller profile information
Walmart's official registration guide includes adding marketplace info and managing shipping among the seller account setup steps.
8. Pre-Application Document Checklist
Before applying for a Walmart US seller account, you can use this checklist:
- Is the company incorporation document ready?
- Does the company name match official documents?
- Is the company address correct and consistent?
- Is the tax ID or business license number ready?
- Are the authorized person's identity details ready?
- Does the payment account align with company info?
- Are product categories clear?
- Is customer service information ready?
- Does every field on the application match official documents?
Applying without completing this checklist can stretch the process or lead to rejection.
9. Most Common Document Mistakes
The most common document and information mistakes in Walmart applications:
Different spelling of the company name. The company name in official documents and on the application form must be identical.
Wrong tax information entered. Errors in the tax ID or business license number cause verification issues.
Missing supporting documents. If documents that verify the company are missing, Walmart may run additional review.
Payment account in a different person's or company's name. When the payment infrastructure doesn't match company info, the application stalls.
Unprofessional store information. Missing customer service info or a vague operations plan makes the application look weak.
