Bank Account Routing Identifiers

Account, bank, branch, and country identifiers used to route domestic and cross-border payments to the intended financial account.

Bank Account Routing Identifiers distinguishes the codes that identify a customer account from those that identify a financial institution or payment route. A Bank Account Number identifies the account inside a provider’s records, while a U.S. Routing Number or U.K. Sort Code supplies domestic institution or routing context.

For countries using ISO 13616, an IBAN combines a country code and check digits with a country-specific BBAN. A SWIFT code or BIC identifies an organization in financial messaging rather than the customer account.

Always match the identifier to the country, payment rail, account, and instruction date. A checksum-valid or reachable code reduces routing errors but does not prove account ownership, payee identity, authorization, or fraud absence.
