Global Business ID Validator API

Global Business ID Validator API — Validate 30+ business identifiers from a single endpoint with one subscription.

Why a bundle? Because every fintech onboarding, e-commerce checkout, and KYC workflow needs to validate multiple identifiers. Buying 30 separate APIs is a procurement nightmare. One subscription, one API key, one bill.

Validators included (POST ):

• Banking: IBAN, BIC, SWIFT, BSB (AU), ABA routing (US), credit-card Luhn + brand detection (Visa/MC/Amex/Discover/JCB/Diners)
• Tax & business IDs: VAT (28 EU countries), EIN, EIN-format, US/Canada/Brazil/Mexico tax IDs (SSN, SIN, CPF, RFC, ITIN)
• Securities: ISBN-10/13, ISIN, CUSIP
• Devices & networks: IMEI, MEID, MAC address, IP (v4/v6)
• Postal & contact: postal code (9 countries), email syntax + disposable detection, username, domain, BIN lookup
• Logistics: shipping tracking number (UPS/FedEx/DHL/USPS detect)
• Industrial: VIN (vehicle, with year + country)

Who it's for

• Fintech onboarding teams running KYC/AML
• E-commerce checkout flows validating cards, addresses, tax IDs
• SaaS billing systems needing accurate VAT + EIN
• Logistics platforms parsing tracking IDs
• Anyone tired of maintaining 30 regex libraries
