VAT Number Verification for Amazon Sellers: UK & EU Requirements

A VAT number is only valid to Amazon if the business name on it matches your legal name in Seller Central, character for character. Get that wrong and it doesn't matter whether the number is real — Amazon's system won't accept it.

This trips up newer EU and UK sellers constantly, usually right after they've cleared KYC and think the hard part is over. It isn't. VAT verification runs its own checks, against its own databases, and a mismatch here blocks listings the same way a KYC rejection does.

Do you actually need a VAT number to sell on Amazon?

If you're a UK business with turnover over £90,000, or you store inventory or sell into the EU past the €10,000 distance-selling threshold, yes — and for FBA sellers specifically, storing inventory in a country creates a VAT obligation there regardless of turnover. Amazon will ask for a VAT number before enabling listings or Pan-EU FBA in the affected marketplaces.

The threshold conversation trips people up because it sounds optional until you read the FBA exception. Amazon's fulfillment network moves inventory across EU warehouses automatically under Pan-EU FBA — the moment stock physically sits in Germany or France, you likely owe VAT registration there, whatever your revenue is.

How Amazon actually verifies a VAT number

Amazon checks your VAT number against the relevant government registry — VIES for EU numbers, HMRC's own checker for UK numbers — and confirms the registered business name matches what's on file in Seller Central. These are two separate systems since Brexit, and a number valid in one won't be recognized by the other.

• VIES (VAT Information Exchange System) — validates VAT numbers issued by EU member states against each country's tax authority
• HMRC's UK VAT checker — validates UK numbers separately; a UK-only number won't appear in VIES at all
• A Certificate of VAT Registration — Amazon may request this directly if the automated check doesn't resolve

Why VAT verification stalls

• Business name on the VAT certificate doesn't exactly match your Seller Central legal name
• Number format doesn't match the country prefix Amazon expects (e.g. missing the "GB" or country code)
• The number is genuine but not yet active in VIES — new registrations can take days to weeks to propagate
• Amazon's "Establishment" request goes unanswered — a separate check confirming where your business is genuinely based, sent to a dedicated KYC tax mailbox

That establishment question catches people off guard because it feels redundant — you already gave Amazon a registered address. But UK and EU VAT law asks where a business is genuinely established, not just registered, and Amazon documents the answer separately from your account address.

What happens if VAT verification fails

Failed or stalled VAT verification blocks listings in the affected marketplace, can suspend Pan-EU FBA eligibility, and in persistent cases leads Amazon to withhold disbursements until it's resolved. It doesn't usually take down your whole account — it quietly switches off the marketplaces that need it.

The fix is rarely dramatic. Most stalls are a name mismatch or a registration that hasn't finished propagating through VIES yet — worth checking both before assuming there's a deeper problem.

Frequently Asked Questions

What's the difference between VIES and the UK VAT checker?

VIES validates VAT numbers issued by EU member states against each country's registry; the UK left VIES after Brexit and runs its own separate checker through HMRC. A UK VAT number won't show up in VIES, and an EU number won't validate through HMRC's system — sellers registered in both regions need to keep the two numbers, and the two verifications, straight.

Do I need a separate VAT number for every EU country I sell in?

Not necessarily — the EU's One Stop Shop (OSS) scheme lets many sellers report cross-border EU sales through a single VAT return, but FBA sellers storing inventory in a specific country still generally need a local VAT registration there, separate from OSS.

How long does Amazon VAT verification usually take?

A few business days once the number and Establishment documentation are both correct and in the right queue — but a newly issued VAT number that hasn't yet appeared in VIES can add days to weeks on top of that, independent of anything Amazon controls.
