Key takeaways
- Walmart registration requires a Business Tax ID, such as an Employer Identification Number, or a business license, plus documents that verify your legal business name and address, and an SSN is not accepted.
- Walmart tracks more than one address: your registration address, the Walmart facility that ships fulfillment orders, and a separate US return address you provide.
- A PO Box cannot be used for a Walmart return center, which has to be a physical US address, so a deliverable business address is the cleaner choice.
Before you start
- Have a Business Tax ID or business license ready, since Walmart will not accept an SSN to register.
- Decide on one business address you can keep consistent across registration, your bank, and your tax filings.
Who this is for
- Sellers applying to Walmart Marketplace for the first time.
- Sellers using Walmart Fulfillment Services who need a US return address.
- Non-resident and multi-state sellers deciding which address to register.
Walmart Marketplace asks new sellers for a verified business name and address along with a tax ID, and it keeps track of more than one address once you are selling. Choosing the right business address up front is what keeps registration and returns from stalling later.
This guide covers what Walmart requires to register, the different addresses it tracks, whether a PO Box or virtual address works, and how 1099-K reporting fits in.

What Walmart Requires to Register
Walmart Marketplace leans on proving your business is real, so the application is verification-heavy. The core requirement is a business tax identity plus documents that confirm your name and address.
- You need a Business Tax ID, such as an Employer Identification Number, or a business license number, and an SSN is not accepted.
- Walmart asks for supporting documents that verify your legal business name and your business address.
- A government-issued photo ID for the applicant or an authorized representative is part of the check.
The tax identity and the tax form are separate steps. The Business Tax ID gets you qualified to register, while the W-9 with your business name, address, and taxpayer ID is completed when you set up tax and payment details.
The Addresses Walmart Tracks
Sellers often assume there is one address, but Walmart separates a few roles, especially once you use its fulfillment service. Keeping them straight avoids exposing the wrong address.
| Address | What it is |
|---|---|
| Registration address | The business address you verify when you apply, tied to your tax identity |
| Fulfillment ship-from | When you use Walmart Fulfillment Services, known as WFS, orders ship from a Walmart facility, not from you |
| WFS return address | A separate US address you set in Seller Center, where unsellable returns are sent back to you |
With Walmart Fulfillment Services, the address customers see on a shipment is a Walmart facility, while your return address is the US address you provide.
The address you enter is what appears on your account and your return labels, so it is the business address you provide rather than your home address that customers and carriers see.

Can You Use a PO Box or Virtual Address?
A PO Box does not work where Walmart needs a physical location. Walmart explicitly states that a PO Box cannot be used for a return center, which has to be a physical US address, and Hawaii, Alaska, and US territories are excluded for that return address.
Because returns and verification lean on a real, deliverable address, the practical choice is a genuine US business address that receives mail. You can confirm an address is valid and deliverable with our free Address Checker before you enter it in Seller Center.
A real business address also keeps your home off your account and your labels, which is the outcome most sellers are actually after when they ask about a PO Box.
1099-K and Seller Taxes
As a marketplace, Walmart reports your sales on a Form 1099-K once you cross the reporting threshold. That threshold has changed repeatedly, so the current numbers matter.
- For tax years 2025 and 2026, a 1099-K is issued when your gross sales exceed $20,000 and you have more than 200 transactions, and both conditions have to be met.
- This reverted from the lower $600 rule, so figures you saw in earlier years may be out of date.
- The business name, address, and taxpayer ID on your tax form should match your registration, since mismatches can delay payments or filings.
Reporting thresholds have moved more than once in recent years, so it is worth confirming the current rule before each tax season rather than relying on an older figure. This reflects guidance as of late 2025.
Non-Resident and Multi-State Sellers
International sellers can join Walmart Marketplace, but the bar is higher. Sellers based outside the United States have to provide additional verification beyond the standard documents, so a clean US business identity helps.
- You generally need a US business identity with a Business Tax ID, and international sellers face extra verification rather than a simple sign-up.
- If you store inventory in several states or use Walmart Fulfillment Services, your sales-tax footprint can spread, which ties back to where your business is registered.
- Keeping one consistent business address across registration, your bank, and your filings reduces the mismatches that slow approval.
A real US business address in the city that fits your filings is the anchor for all of this. You can set one up through save office onboarding, often within a day, and keep it consistent across Walmart, your formation papers, and your bank.
Selling on Walmart Marketplace comes down to a verified business identity and a real address that holds up across registration, returns, and taxes. The tax ID qualifies you, the documents confirm your name and address, and Walmart Fulfillment Services adds a separate return address you should not overlook.
Pick one genuine US business address, confirm it is deliverable, and use it everywhere. That keeps your home address off your account, satisfies the return-address rule, and lines up with the tax form Walmart files on your sales.
