Overview

If you intend on selling on the U.S. Marketplace, you’re required to provide a business tax ID or business license number, and supporting documentation to confirm your company’s credentials. Keep reading below to find out your tax classification and what documentation is required for your country of incorporation.

How does it work?

W-9

If you're a U.S.-based seller with an Employer Identification Number (EIN) and your country of incorporation is in the United States, your tax classification is W-9. We may ask for additional documentation, such as:

An IRS-issued EIN verification letter (IRS LTR 147C) or IRS-issued SS4 confirmation letter (IRS LTR CP 575). 
A state-issued business license, registration certificate, articles of incorporation or a Certificate of Good Standing.

If you don't have a U.S. Business Tax ID, you can apply for one here.

Pro tip

If you don’t have a U.S. state registration number, you can get it from your state's Secretary of State website (or a similar business filing division). 

W-8ECI

If you have an Employer Identification Number (EIN) and your country of incorporation isn’t the United States, your tax classification is W-8ECI. For supported Countries of Incorporation (COIs), you can onboard by providing your COI tax ID details on the business verification tile. For certain COIs, we don’t accept COI tax ID and you may have to provide a U.S. tax ID to set up your account.

W-8BEN-E

If you don't have an EIN and your country of incorporation is not the United States, your tax classification is W-8BEN-E. We support this tax classification for sellers from China, Hong Kong, the United Kingdom of Great Britain and Northern Ireland (U.K.), Japan, Canada, Mexico, India, Singapore, South Korea, Taiwan, Germany, Vietnam, Thailand, Chile and Turkey.

W-8BEN

We only support this tax classification if you’re a sole proprietor from Mexico or India, i.e., an individual who owns and operates an unincorporated business by themselves. If you're a sole proprietor from Mexico, you can only onboard to the Mexico market.

Additional guidelines

To successfully set up your account, you must also have the tax information for your business in the selected country of incorporation along with a personal ID of the applicant or legal representative, business address, legal business name and business phone number. This table shows the required proof needed for W-8BEN-E and W-8BEN sellers from the countries listed above.
