Walmart Marketplace is the second-largest online marketplace in the US, and unlike Amazon, Walmart doesn’t let everyone in. Every seller goes through an application review. The good news: most rejections come from a handful of avoidable mistakes. This guide walks through exactly what Walmart looks for in 2026 and how to put together an application that gets approved the first time.

Why Walmart vets its sellers

Walmart protects its customer experience by keeping the seller base smaller and more reliable. That’s why fewer sellers compete for each listing than on Amazon, and why an approved account is worth taking seriously. The review is designed to answer one question: will this seller ship on time, answer customers, and sell genuine products? Everything in your application should help Walmart answer “yes”.

What you need before you apply

• A registered business. A US business with an EIN, or a registered business in one of the countries Walmart currently accepts. Your legal business name must match your tax documents exactly.
• Tax forms. A W-9 for US businesses (or the relevant W-8 form for non-US businesses).
• Proof of address and identity. A business address and the details of the primary contact or owner.
• A bank account for payouts that is in the business’s name.
• Marketplace or e-commerce history. Sales history on Amazon, eBay, Shopify or another channel is one of the strongest signals you can give.
• A product catalog plan. What you’ll sell, how many SKUs, and whether products have GTINs/UPCs (Walmart requires valid product identifiers for most items).
• A fulfillment plan. How you’ll ship: yourself, through a 3PL, or with Walmart Fulfillment Services (WFS). Walmart expects fast, tracked shipping and a US returns process.

Step-by-step: submitting the application

1. Start at Walmart Marketplace (marketplace.walmart.com) and choose to apply as a seller.
2. Enter your business details exactly as they appear on your tax records. Mismatched names, addresses or tax IDs are the number-one cause of rejections.
3. Describe your business. Add your website, your marketplace store links, your annual online revenue and the categories you sell in.
4. Explain your catalog and fulfillment. Be specific: product types, SKU count, product identifiers, where inventory is stored and how orders ship.
5. Review and submit. Double-check every field. A clean, consistent application gets reviewed faster.

The most common reasons applications get rejected

• Details that don’t match. The business name on the application differs from the EIN letter, or the address differs from the bank account.
• No sales history. A brand-new business with no track record anywhere is a harder approval.
• Restricted or unclear products. Categories that need extra approval, or listings that look like they may infringe a brand.
• A vague fulfillment plan. “We’ll figure out shipping later” is not a plan. Walmart wants to see fast, tracked delivery.
• An unprofessional online presence. A broken website or an empty store link works against you.

How to strengthen your application

Lead with your best numbers. If you have strong ratings on another marketplace, include the store link and your revenue. Show product authenticity: brand authorization letters or invoices from real suppliers make a difference in regulated or branded categories. Pick a fulfillment option you can actually deliver on. Many new sellers choose Walmart Fulfillment Services (WFS) because Walmart handles storage, shipping and returns, which removes the biggest operational risk from the review.

After approval: the first 30 days matter most

Approval is the start, not the finish. New Walmart stores are watched closely, and your early performance sets the tone for your account. Focus on:

• On-time shipping and valid tracking on every order.
• Fast customer responses (aim for well under 48 hours).
• Low cancellation rates: only list stock you actually have.
• Complete, keyword-rich listings with good images, so your products can be found.

Keep an eye on your Seller Scorecard in Seller Center from day one. Walmart uses it to decide which sellers get the Buy Box, the badges and room to grow.

Frequently asked questions

How long does Walmart Marketplace approval take?

Most complete applications get a decision within a few business days to two weeks. Incomplete or inconsistent details (a business name that doesn’t match your tax records, for example) are the most common reason for delays.

Do I need an EIN to sell on Walmart?

US sellers apply with a US business tax ID (EIN). Walmart also accepts sellers from a growing list of other countries with their own business registration documents; check the current eligibility list in Seller Center before you apply.

Can I reapply if Walmart rejects my application?

Yes. Fix the reason for the rejection first: add marketplace history, strengthen your catalog or correct your business details, then reapply. Reapplying with the same information usually gets the same result.

Do I need experience on other marketplaces?

It isn’t a written rule for every seller, but a proven track record on Amazon, eBay or your own store is one of the strongest signals in an application. If you have it, show it.
