Overview

Amazon requires sellers operating on its European Union and United Kingdom marketplaces to provide valid Tax Identification Numbers (TINs) as part of their account setup and tax compliance obligations. Each EU member state and the UK uses its own specific TIN format, and entering an incorrectly formatted number can delay your registration or trigger compliance issues. This guide breaks down the accepted TIN formats for individual sellers, business sellers, and VAT registration numbers across all EU countries and the UK.

Key Points / What Sellers Need to Know

• TIN submission is mandatory — Sellers listing products on any of Amazon's EU or UK stores must provide a valid TIN through Seller Central to remain in compliance with regional tax regulations.
• Formats vary by country and seller type — Individual sellers and business entities use different TIN structures in most countries, so you must submit the correct version for your registration type.
• Incorrect formatting triggers rejections — Amazon validates TIN syntax against official databases such as the European Commission's TIN online check module and VIES (VAT Information Exchange System), so even small errors will cause submission failures.
• VAT numbers are separate from TINs — In addition to your national TIN, you may also need to provide VAT registration numbers, which follow yet another country-specific format.
• Consult a tax advisor if unsure — Given the complexity of cross-border tax obligations, Amazon recommends working with a qualified tax professional to ensure your submissions are accurate.

How to Submit Your TIN on Seller Central

To add or update your TIN, log in to Seller Central and navigate to your account settings. From the left-hand menu, select the tax information section, then click on the VAT/GST registration option. Under the "VAT/GST registration numbers" tab, you can add your TIN along with any applicable VAT registration numbers. Make sure the number you enter matches the exact format required for your country and seller type — including the correct number of digits, any required letters, and any separator characters such as hyphens or slashes.
