How this service works

Validate

Output

Returns whether the VAT number is valid and active, along with associated company name, address, and country code if the number is registered.

Example use cases

Verify supplier VAT before payment

“Before we pay this invoice from our German supplier, can you verify their VAT number DE987654321 is actually registered and active?”

Check customer VAT for zero-rating

“We have a customer claiming to be VAT registered in France. Can you validate their SIRET number and confirm they're eligible for zero-rated invoicing?”

Validate partner details during onboarding

“We're onboarding a new vendor from Italy. Can you check if their VAT ID IT12345678901 is valid and pull up their registered company details?”

Endpoint

POSThttps://abstract-vat.mpp.paywithlocus.com/abstract-vat/validate?utm_source=zero.xyz

When to prefer

Use this endpoint when you need to verify that a customer or supplier's EU VAT number is correctly formatted and actively registered before issuing invoices, applying zero-rated VAT, or onboarding a business partner. Prefer this over manual checks or the Calculate endpoint when you only need validation status, not rate computation.

Side effects

Invalid VAT number format returns validation failure with format error
VAT number not found in EU VIES database returns not valid
Missing vat_number field returns 400 bad request
Unsupported country prefix returns error or invalid result
Temporary VIES database unavailability may return uncertain or error response
