About 6 minutes to read · Rules checked against official Amazon seller documentation, the European Commission's VIES guidance and GOV.UK on 12 November 2026
Short answer: If Amazon rejects a VAT number or flags a mismatch, check the number on the official register, then make sure the legal name and tax address in Seller Central match those records exactly. Use the European Commission's VIES tool for an EU VAT number, or HMRC's checker for a UK number. Amazon says it verifies VAT registration numbers and that this may include checks against VIES.
This guide is only about a rejected or mismatched number in Seller Central. It is not the checklist for switching provider after Amazon VAT Services ended, and not the FBA VAT guide. If you still need to obtain a UK number, see UK VAT registration for overseas companies or the UK VAT registration service. For "do I need a UK number?", see Do overseas sellers need UK VAT?. For help across the UK and EU, see our Amazon and e-commerce seller VAT services.

Why Amazon rejects a VAT number or flags a mismatch
Amazon's official VAT Calculation Service FAQ says it verifies a seller's VAT registration number, which may include checks against the EU's VAT Information Exchange System (VIES). Its European VAT Education guide adds that once you upload a number in Seller Central, Amazon automatically checks it against the VIES database. Allow 1 to 4 business days for a new number to complete verification.
VIES is the Commission's search tool. It returns valid or invalid based on the national tax authority's records. Your Europe lists these official reasons for an invalid result:
- the VAT number does not exist
- the VAT number has not been activated for intra-EU transactions
- the registration is not yet finalised (some EU countries require a separate registration for intra-EU transactions)
Those changes are not always reflected immediately. If VIES is temporarily unavailable, wait and try again. VIES covers VAT numbers issued by EU Member States. It does not cover UK VAT numbers, because the United Kingdom left the EU VAT system on 1 January 2021. Check a UK number with HMRC's "Check a UK VAT number" service, which confirms whether it is valid and shows the name and address of the business it is registered to.
A valid number can still be rejected if Seller Central does not match the tax authority. Amazon's official compliance guide for the Germany store treats a name or address mismatch as a reason a number is declined: the company name on your tax ID certificate must match the name on Amazon, and the address in Seller Central must match the address registered with the tax authority. Abbreviations or a truncated address can be enough for an automated check to fail. Use the same matching principle in other countries, including the UK, once you have the official name and address.
The type of number also matters. Amazon distinguishes an EU VAT registration number — validated and listed in VIES, with a country prefix such as DE, FR, IT or ES — from a local VAT number, which has no country prefix and is in principle only for domestic transactions. If you enter a local number, or select the wrong country for an EU VAT ID, the VIES check will not succeed. Amazon also asks for a VAT number for your default ship-from location and for countries where it stores your FBA inventory. A missing or unvalidated number in the ship-from country can stop the VAT Calculation Service working correctly for those shipments.
How to fix a rejected or mismatched Amazon VAT number
Work through these checks in order. Do not keep re-uploading a number that is still invalid on the official register.
- Read Amazon's message. Note which number and country were rejected, and follow the appeals or Seller Support instructions in that notice.
- Check the number on the official tool. For an EU number, open VIES, select the correct Member State and enter the number without a space before or after it. For a UK number, use Check a UK VAT number and note the exact name and address HMRC shows.
- If the official check is invalid, fix the registration first. Ask the tax authority, or your VAT agent, to confirm the number, activate it for intra-EU transactions if required, and finish any separate VIES registration. In Italy, non-EU businesses that want the number included in VIES may also need a guarantee — see Do you need a fiscal representative for EU VAT?. Once the official checker shows the number as valid, upload it again and allow 1 to 4 business days.
- If the official check is valid, match the legal name and tax address. Compare Seller Central with the official record or your VAT certificate, character for character. Typical differences include a trading name instead of the legal name, missing legal-form words (Ltd, GmbH, S.r.l.), or an abbreviated street name. Correct Seller Central if it is wrong; ask the tax office to amend its record if that is wrong. If the details match in substance but not in format, Amazon's documented route for German VAT numbers is to email de-vat-number-appeals@amazon.com with your German VAT number, the name or address used on Amazon, an explanation of the difference, and a copy of the German VAT registration certificate, and ask for a manual review. For other countries, including the UK, use the appeals or Seller Support route in your rejection notice. Unofficial mailbox addresses from seller forums are not cited here, because they are not in official Amazon help and they change.
- Enter the right type of number, for the right country. In Seller Central, go to Settings and then Tax Settings (Amazon also refers to the Tax Registrations page under Account Information). Use the EU VAT ID with the correct country prefix, not a domestic local number. Add a number for every country from which you ship, or in which Amazon stores your stock.
- Wait, then follow up if needed. If the official register is valid, the name and address match, and Amazon still rejects the number after several business days, open a Seller Support case and attach the official checker result or certificate.
How PanVAT can help
If the number is valid but Amazon will not accept it, or you do not yet have a number where Amazon stores your stock, we can review the official records and your registrations in a free consultation. VAT registration is free with an annual plan. Published EU prices start at €79 per country per month, billed annually, or €90 paid monthly, on our pricing page. For non-EU clients, prices may differ due to local VAT regulations for non-EU sellers. No UK prices are quoted, because pound sterling amounts have not been set.
