Find a VAT number by company name
BEFORE YOU START
Collect the inputs that prevent a false match.
- Legal company name from a current business document
- Country where the entity is registered
- Registration number, address or region when available
- Legal suffix such as Ltd, GmbH, S.r.l. or LLC
- A separate authority route if current tax-registration status matters
SOURCE MAP
Use the source that answers the actual question.
| Question | Evidence source | Retain |
|---|---|---|
| Which legal company is this? | Company record or business registry | Legal name, jurisdiction, registration number, address and source |
| Which tax ID is reported for that company? | Company document or company-data record | Identifier, identifier type, source and retrieval date |
| What does the tax authority currently report? | Relevant national authority or VIES where applicable | Authority response, date and reference when supplied |
| Should the supplier or customer be approved? | Your organisation's policy and independent controls | Decision, reviewer, exceptions and supporting evidence |
1. Start with the right company name
A trading name and a legal company name may be different. Before searching, look at the business name on your contract, invoice, or supplier onboarding form. Keep any registration number and registered address alongside it.
In VATFind, choose Company name and the country where that legal entity is registered. Enter the name without adding a tax number to the same field. For the United States and Canada, a state or province can help narrow the search.
2. Compare the matches
A similar name is not enough to identify a business. Compare the country, registration number, and available address. A group of companies can have several subsidiaries, and the entity you pay may not be the entity whose brand appears on a website.
If VATFind returns several records, select the one that matches your documents. The result opens the available details for that record. Do not choose the first name simply because it looks familiar.
3. Find the available tax ID
The company record displays a VAT or tax ID when the source supplies one. A blank field means that the number was not supplied in that result; it does not establish that the company is unregistered.
For UK businesses, GOV.UK also points to invoices, receipts, and company websites as places to find VAT numbers. If you still cannot identify it, ask the supplier directly.
GOV.UK: Check a UK VAT number4. Understand what the number check confirms
Finding a number in a company record is different from confirming its tax registration status. VATFind can also check whether a number links to a company-data record, but that company-record match is not a live tax-authority result.
When a decision depends on current tax registration, use the relevant official authority service and keep its result with your records. If the details do not match, resolve the discrepancy with the company before relying on the number.
What if the search returns no match?
Check the country, spelling, legal suffix, and any state or province. Try the name exactly as it appears on a recent business document. An empty result means no matching company record was returned for that search.
Each completed search, including a search without a match, uses one daily allowance. An upstream service error does not use a free search.
Choose the source for the question you are answering
A company registry, a tax-authority service, a supplier document and a commercial company-data record do not prove the same fact. The registry helps identify the legal entity. A tax service reports its response for a tax registration. A supplier document shows what the business submitted. VATFind helps connect those pieces without turning them into one unexplained pass or fail.
Before relying on a number, write down the decision it will support. If the task is data enrichment, a sourced company record may be sufficient. If the task is tax treatment, onboarding approval or payment release, follow the separate authority, document, bank, sanctions or policy controls required by that workflow.

Save the original search input, the candidate selected, the legal name, jurisdiction, registration number, tax identifier, returned source and retrieval time. If several candidates appeared, retain why one was chosen. If the field was unavailable, keep that state instead of inserting an inferred number.
When a separate authority check is required, store it as a second evidence item with its own date and reference. This makes later review easier when a supplier changes legal entity, a registration changes, or a source returns a different result.
PRACTICAL QUESTIONS
Frequently asked questions
Can a trading name be used to find a VAT number?
It can be a starting clue, but the number should be taken only after the underlying legal company is resolved. Compare registration number, address and jurisdiction rather than relying on the brand name alone.
Why are several companies returned for one name?
Company names are not globally unique. Similar names, local subsidiaries and separate group entities can all appear. Add country, legal suffix, state or province, registration number or address to narrow the candidates.
Does a missing VAT field mean the company is not registered?
No. It means the returned company record did not supply the field. Coverage, source publication and the selected entity can all affect availability.
Is a VATFind match an official tax-authority check?
No. VATFind's company-record association and a current authority response are separate evidence. Use the relevant official service when that status is required.
What should be saved with the number?
Keep the submitted name, selected legal company, jurisdiction, identifiers, source, retrieval time and any separate authority response or reviewer decision.
