Choose the registration country
Use the country where the legal entity is registered, not simply where its website or brand operates.
VAT NUMBER LOOKUP BY COMPANY NAME
Find a company VAT number using its legal name and country. Compare matching companies, registration details and the VAT or tax ID available in the record.
THE PRACTICAL ANSWER
Enter the legal company name and registration country, then compare the returned company number and address with your supplier documents. VATFind displays a VAT or tax ID when it is available for that company record. This is useful when the identifier is missing: a VAT-number checker normally starts with a number you already know. If the record has no tax ID, ask the company for its current invoicing details.
BEFORE YOU SEARCH
This planning check stays in your browser and sends no company details. It helps you avoid choosing a VAT number from the first similar-looking result.
Confirm the missing detail before treating a candidate company as the supplier or customer you mean.
THE WORKFLOW
Use the country where the legal entity is registered, not simply where its website or brand operates.
Use the name shown on a contract, invoice, or registry document. Include the legal suffix when you know it.
Match the registration number, address, region, and status before opening the company record.
Use the VAT or tax ID only when the selected company record and your business document refer to the same entity.
WHAT VATFIND DOES
VATFind searches the selected country for the legal company, separates similar names using registration details and returns the VAT or tax identifier reported for the matched company record, together with its source and retrieval time.
Evidence meaning: a verified association means the submitted VAT number or EIN is linked to the returned company record. It is not, by itself, confirmation of current tax-registration status, tax compliance or approval of the wider transaction.
For API checks, use vat_number outside the US and tax_identifier for US EINs. Optional fields can be absent when a source does not provide them.
CHOOSE THE RIGHT APPROACH
Start with the legal name and country to discover a company record and its available tax identifier.
Start with an existing number and identify the company associated with it. Use this to investigate a number on an invoice.
Start with the number and obtain the authority response relevant to that tax registration. Keep it alongside the company lookup.
CONTROL OWNERSHIP
A reliable workflow names who owns the input, who interprets the company evidence and who makes the wider decision. That separation prevents a data result from becoming an unexplained approval.
Identify the invoicing entity before a vendor record or invoice is updated.
Resolve the legal supplier behind a trading name during onboarding.
Approve additions to the tax-ID field and preserve the evidence used.
DECISION DESIGN
| Stage | Evidence to retain | Controlled action |
|---|---|---|
| Search | Legal name, registration country and any known address or company number. | Return candidates without silently selecting a similar name. |
| Resolve | Registration number, legal form, address and company status where available. | Select the entity only when the record agrees with the business document. |
| Use the number | Source-reported VAT or tax ID, source label and retrieval time. | Populate the identifier with its evidence; route missing or conflicting fields for review. |
EXAMPLE WORKFLOW
A procurement team receives a contract bearing a brand name, while the invoice will be issued by a local subsidiary. Search the legal name in the contract's company-information section, choose its registration country and compare the registration number with the candidate records. Add the returned VAT number only after selecting that entity. If the parent appears first, opening its record does not resolve the subsidiary. Preserve the name originally submitted so the next reviewer can follow the selection.

WHAT TO MEASURE
Track operating quality rather than claiming that a company match guarantees the downstream outcome.
READ THE RESULT CORRECTLY
VATFind can surface a source-reported identifier from a company record. If your decision depends on current VAT-registration status, make a separate check with the relevant tax authority. For example, HMRC’s UK service requires the VAT number and cannot search by company name.
Review data and limitationsFREQUENTLY ASKED QUESTIONS
Yes, when the company-data source returns a matching record and supplies a VAT or tax ID. Use the legal name and registration country, then compare the entity details before using the number.
Compare registration numbers, addresses, regions, and legal forms. Do not take a VAT number from the first result merely because the name looks familiar.
The source may not supply that field for the record. VATFind returns the field as unavailable.
No. It returns company-record information and match context. Use the relevant authority service when a separate registration-status response is required.
A Companies House registration number identifies the incorporated company. It is a separate identifier from its VAT number. Use the company record to establish the entity, then look for its tax identifier in VATFind or the company's documents.
Name lookup helps discover a missing number. HMRC's checker needs the VAT number before it can return a registration result; it cannot search by company name.
Use the legal supplier name and registration country, then compare registration number and address with current supplier documents. Preserve the selected entity and source-reported tax ID. Obtain a separate authority response when your onboarding policy requires current tax registration evidence.
Look for the legal entity on the contract or invoice before searching. Several subsidiaries may share a brand, so add a registration number, address or jurisdiction to distinguish the company that will issue the invoice.
A compatible agent can use VATFind's find_vat_number MCP tool with company_name and country_code. The client connects through OAuth, asks when the company is ambiguous and retains the returned sources and result states. Live searches require paid workspace access.
Use POST /v1/companies/search with name and country_code, a Bearer API key and a stable Idempotency-Key. Start with deterministic sandbox fixtures, then evaluate an agreed live supplier sample. Read the supplier onboarding integration guide for coverage, evidence and cost requirements.
