#swift

SWIFT/BIC business-identifier-code validation and parsing as an API, computed locally and deterministically. The validate endpoint checks that a code follows the ISO 9362 BIC structure — four letters for the institution, a two-letter ISO country code, a two-character location code and an optional three-character branch code, eight or eleven characters in total — ignoring spaces and upper-casing the input, and confirms the country code is a recognised one; DEUTDEFF (Deutsche Bank, Frankfurt) is a valid eight-character head-office BIC and DEUTDEFF500 a valid eleven-character branch BIC. The parse endpoint breaks a BIC into its institution, country, location and branch components, reports whether it is a head office or a branch (branch XXX or none means the head office), and reads the status from the location code’s second character — 0 for a test/non-SWIFT code, 1 for a passive participant and 2 for reverse billing. A BIC carries no checksum, so this is structural validation. Everything is computed locally and deterministically, so it is instant and private. Ideal for fintech, banking, payment, KYC, treasury and accounting app developers, SWIFT-code and bank-identifier tools, and onboarding flows. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 2 endpoints. This validates and parses a BIC; for IBAN account-number validation use an IBAN API.

Validate the bank and provider identifiers that move money and records — all checked locally, with no lookups. The bic endpoint validates and parses a SWIFT/BIC code (ISO 9362): it confirms the 8- or 11-character format, splits out the bank, country, location and branch codes, checks the country against ISO 3166, and flags test and passive-participant codes. The aba endpoint validates a US ABA routing number by its checksum (the 3-7-1 weighting) and names the Federal Reserve district from the prefix. The npi endpoint validates a US National Provider Identifier by its Luhn check digit over the 80840 prefix and reports whether it is an individual or organization NPI. Everything is computed locally and deterministically, so it is instant and private — it checks the structure and check digits, not whether the institution actually exists. Ideal for payments and banking, fintech onboarding and KYC forms, healthcare billing and clearinghouses, and form and data validation. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 4 endpoints. This validates BIC, ABA and NPI; for IBAN use an IBAN API and for payment-card numbers use a credit-card API.
