Tools (5)

validate_ibanValidate an International Bank Account Number: mod-97 checksum, length for its country (100+ countries), SEPA membership. Returns the normalized and formatted IBAN, country and BBAN, or machine-readable error codes. Use before paying an invoice or saving supplier bank details.
validate_bicValidate a BIC/SWIFT code (8 or 11 chars): structure, ISO country, test-BIC flag. Pass the IBAN too and it checks that the BIC country matches the IBAN country (a common fraud/typo signal).
validate_eu_vatValidate an EU VAT ID (27 member states + XI): format and check digit offline. Set live=true to also query the EU VIES registry for registration status, company name and address (slower, may be throttled; failures return vies.checked=false, never a false 'invalid').
validate_gb_vatValidate a UK (GB) VAT registration number: format, branch/government/health-authority types, and the HMRC mod-97 / 9755 checksum.
validate_einValidate a US Employer Identification Number: 9-digit format and a valid IRS campus prefix. EINs have no check digit, so this catches typos and fake prefixes, not every invalid number.
