Walmart Marketplace is not an open sign-up. Unlike marketplaces that let anyone list the same day, Walmart reviews every seller application — your business, your tax documents, your selling history, and your catalog all get checked before you can sell a single item. That gate is exactly why many sellers want in (less competition from fly-by-night sellers), and exactly why so many applications stall or get declined.
This guide walks through what Walmart actually requires — based on Walmart's own Marketplace documentation — the application steps in order, the deadlines that trip sellers up, and the most common reasons applications fail and what to do about each one.
The eligibility checklist: what Walmart requires before you apply
Walmart's stated requirements for Marketplace sellers:
- A registered business. You apply as a business entity, not as an individual. Walmart asks for a Business Tax ID or a Business License Number — a Social Security Number is explicitly not accepted as a substitute.
- Documents that verify your business name and address. The details you enter must match these documents exactly (more on why that matters below).
- A history of marketplace or eCommerce success. Walmart lists this as a requirement outright. Brand-new sellers with no track record anywhere are the weakest applicants.
- Products with valid GTINs. Your items need UPC/GTIN numbers with a GS1 prefix — homemade or recycled barcodes are a problem.
- A catalog that complies with Walmart's Prohibited Products Policy.
- U.S. fulfillment with returns capability. Either a B2C warehouse in the U.S. that can handle returns, or use Walmart Fulfillment Services (WFS).
If you cannot tick every box yet, fix that first. Applying anyway and getting declined mostly costs you time.
International sellers: yes, with conditions
The U.S. Walmart Marketplace is officially open to sellers based in 14 countries: Canada, Chile, China, Germany, India, Japan, Mexico, Singapore, South Korea, Thailand, Turkey, the United States, the United Kingdom, and Vietnam.
International applicants go through the same business verification, with paperwork adjusted to their situation (the tax forms below). If you do not have a U.S. tax ID, Walmart provides an alternate verification path rather than a flat rejection. Sellers based in India, for example, can verify with Indian business documents and receive payouts in INR through providers such as Payoneer or PingPong.
The tax paperwork, by business type
Which form you file depends on where your business is based and how it is classified. Walmart's verification step routes you based on your entity type:
- U.S. business with an EIN → Form W-9. During verification, Walmart may also request supporting documents: the IRS EIN letter (LTR 147C or CP 575), a state business license, articles of incorporation, or a Certificate of Good Standing.
- Non-U.S. business with a U.S. EIN → Form W-8ECI.
- Non-U.S. business without a U.S. EIN → Form W-8BEN-E.
- Sole proprietors in Mexico or India → Form W-8BEN. This is the exception to the "no individuals" rule — and note it applies to those two countries' sole proprietors, not to U.S. individuals.
Have these documents ready before you start the application. Verification pauses while Walmart waits for paperwork, and one deadline below is unforgiving.
The application, step by step
Step 1 — Confirm you meet the requirements. The checklist above. Do not skip it.
Step 2 — Create your account and agree to the terms. Basic business and contact information, plus Walmart's seller agreements.
Step 3 — (Optional) Express setup. Walmart offers an Express path that can import your existing listings from another marketplace (via Versori) to speed up catalog setup. Optional, but useful if you already sell elsewhere — which, per the requirements, you probably do.
Step 4 — Business verification. This is the real gate. You submit your business details and set up payments; Walmart validates your tax ID and entity information against your documents. Depending on what comes back, Walmart may ask for additional documents, and the account holder may be asked to complete an identity check involving photo ID and facial recognition. Verification can take from a few minutes to a few business days.
Step 5 — Store setup. You complete your store details, choose fulfillment (WFS or seller-fulfilled), and finish your catalog. Your items can only publish once setup is complete — an approved account with an unfinished store sells nothing.
The 30-day deadline that quietly kills applications
Here is the trap that catches sellers who "got approved" and moved on: payment setup must be completed within 30 days of submitting your business details. If it is not, the account is declined and you have to apply again.
Payment setup means a Marketplace Wallet or an approved third-party payment provider. Note that ACH direct deposit is not offered — sellers used to Amazon-style bank deposits sometimes stall here looking for an option that does not exist. New sellers should also expect an initial payment hold period once they start selling; it is standard, not a red flag on your account.
How long does approval actually take?
Walmart does not publish an official review timeline, so treat any site promising "approval in X days" as guessing. The official reference points are these: Walmart says onboarding takes about 10 days on average, and the business-verification step itself runs from a few minutes to a few business days. Applications that need extra documents take longer — which is another reason to front-load your paperwork. The 2–4 week figures quoted around the internet are seller anecdotes, not Walmart commitments.
What it costs to join
Joining itself is free: no setup fee, no monthly fee, no hidden fees. Walmart makes its money on a referral fee of 6%–15% depending on category, charged on sales. (Fulfillment through WFS and advertising are separate, optional costs.)
Why applications get rejected — and what to do
Walmart does not publish a rejection-reason list, but its documented verification requirements point at the failure modes, and seller reports consistently corroborate them:
- Business data that doesn't match the documents. A legal name, address, or EIN entered slightly differently than on your tax paperwork fails validation. Fix: re-enter everything character-for-character from the documents, and resubmit.
- No verifiable business entity or tax ID. Applying as an individual, or with an EIN that cannot be validated. Fix: register the business properly first; U.S. individuals outside the Mexico/India sole-proprietor exception cannot apply as individuals.
- Thin or no selling history. Walmart screens for marketplace experience. Fix: build a track record on another marketplace first, then apply — the Express import exists precisely for sellers arriving with a catalog and history.
- Catalog problems. Items without GS1 GTINs, or products on the prohibited list. Fix: audit your catalog against the Prohibited Products Policy and fix barcodes before applying.
- Missing the 30-day payment deadline. Covered above — an "approval" that lapses. Fix: there is no extension in the documentation; you re-apply, this time completing payment setup immediately.
- Incomplete verification. Extra documents or the identity check requested and never completed. Fix: watch for Walmart's requests and respond; support is available through the Help button in Seller Center if your case stalls.
One honest caveat: Walmart's public documentation does not describe a formal appeals process for declined applications. The documented remedies are correcting the problem and re-applying, supplying requested documentation, and opening a support case. Anyone selling you a guaranteed "appeal service" is selling you something Walmart does not describe.
Quick answers
Can I sell on Walmart Marketplace as an individual? Generally no — a registered business with a Business Tax ID or license number is required, and an SSN is not accepted. The only documented individual exception is sole proprietors based in Mexico or India.
How long does Walmart Marketplace approval take? There is no official SLA. Walmart cites about 10 days for average onboarding; business verification alone can be minutes to a few business days, longer if extra documents are requested.
Does Walmart charge a monthly fee? No — no setup or monthly fees. You pay a referral fee of 6%–15% by category on what you sell.
My application was declined. Can I apply again? Yes — re-application is the documented path after a decline (including declines for missing the 30-day payment-setup deadline). Fix the underlying issue first, because the same data will fail the same checks.
The bottom line
Getting approved on Walmart Marketplace is less about persuasion and more about paperwork hygiene: a real registered business, tax documents that match your application to the character, GS1 barcodes, a compliant catalog, a U.S. fulfillment answer, and payment setup finished inside 30 days. Sellers who prepare those six things before clicking "apply" are the ones who experience the "about 10 days" version of onboarding.
