ID & Tax Number Validator — IBAN, VAT, 236+ formats, 88+ countries

Check whether IBANs, VAT numbers, company IDs, tax IDs and national ID numbers are valid, and get them back cleanly formatted. Covers 236 number types from 88 countries.

Use it to clean CRM and supplier data, check customer input at signup or checkout, prepare invoices, or screen large files before importing them.

What it checks

For every number it verifies the length, structure and check digits using each format's official rules, and tells you why a number is invalid:

reason	meaning
invalid_checksum	The check digit is wrong (typo or fake number)
invalid_length	Wrong number of characters
invalid_format	Invalid characters or wrong structure
invalid_component	A part is invalid (e.g. date of birth, region or country code)
no_match	(Auto mode) not valid for any format of that country

Important: this checks that a number is correctly formed. It does not confirm that the number is currently registered to a real company or person, which requires official government registries.

Popular types

Input

{
  "numbers": [
    "GB82 WEST 1234 5698 7654 32",

    {"number": "390.533.447-05", "country": "BR"}
  ],

• Plain strings use the default type (or the default country when the type is Auto).
• Objects can set their own type or country, so you can mix them in one run.
