Amazon's Seller Identity Verification (KYC) checks that your business is a real, registered entity and that you are an authorized representative. For an LLC, Amazon verifies the legal entity name, a beneficial owner's government ID, a valid business address, and a bank account that can receive disbursements. Forming the LLC correctly in your state is what lets you clear each check.
What Amazon Seller Central requires — and how a Washington LLC meets each
| Requirement | How your Washington LLC satisfies it |
|---|---|
| Legal business name match | Use the exact LLC name on your Washington Certificate of Formation; it must match your bank account holder name. |
| Business registration document | Upload your approved Washington Certificate of Formation. |
| Beneficial owner identity | Provide a government ID for each beneficial owner. Washington lists members on public filings, so the names already match state records. |
| Valid business address | Use a US street address registered to the LLC in Washington (your registered-agent or virtual business address). PO boxes are usually rejected. |
| Disbursement bank account | Link a US business bank account opened with your EIN and Certificate of Formation. |
| Tax interview (W-9/W-8) | Complete the tax interview. A US LLC owned by US persons typically submits a W-9 using its EIN; non-US owners of a disregarded-entity LLC generally use a W-8 form instead. |
Washington-specific things to watch
- Washington lists LLC members on public filings, so Amazon Seller Central's beneficial-owner check will line up with public state records — you still upload a government ID for each owner.
- Washington issues a Certificate of Formation rather than "Articles of Organization." When Amazon Seller Central asks for "formation documents," upload your Certificate of Formation.
How to verify your Washington LLC on Amazon Seller Central
- Legal business name match. Use the exact LLC name on your Washington Certificate of Formation; it must match your bank account holder name.
- Business registration document. Upload your approved Washington Certificate of Formation.
- Beneficial owner identity. Provide a government ID for each beneficial owner. Washington lists members on public filings, so the names already match state records.
- Valid business address. Use a US street address registered to the LLC in Washington (your registered-agent or virtual business address). PO boxes are usually rejected.
- Disbursement bank account. Link a US business bank account opened with your EIN and Certificate of Formation.
- Tax interview (W-9/W-8). Complete the tax interview. A US LLC owned by US persons typically submits a W-9 using its EIN; non-US owners of a disregarded-entity LLC generally use a W-8 form instead.
Non-US founders
Non-US owners complete Amazon's same onboarding flow, but the correct tax-interview form depends on your LLC's tax classification. If you are a non-US individual and your US LLC is a single-member disregarded entity (no corporate-tax election), the IRS looks through the LLC to you as the owner — you complete a W-8BEN, not a W-9. If the owner is a foreign entity, use W-8BEN-E. If your LLC has elected to be taxed as a corporation or partnership, it submits a W-9 using its EIN. Using the wrong form can trigger account holds, so confirm your classification with a US tax advisor. Non-US owners may use a non-US government photo ID for identity verification.
