  title: SWIFT SwiftRef Account Numbers National IDs API
  description: The SWIFT SwiftRef API provides automated real-time lookup and validation of payments reference data. Supports validation and retrieval of BICs, IBANs, LEIs, National IDs, country codes, currency codes, and account numbers. Enables financial institutions, corporates, and PSPs to achieve greater straight-through processing rates by validating identifiers before payment execution. Data is updated daily from authoritative sources.
