Scope and limitations

  • Format validity does not prove account existence, ownership or payment acceptance; this is not a bank account lookup.
  • Only ASCII letters, digits and grouping whitespace are accepted; rules come from the local dependency.

Common mistakes

  • Changing one digit can break the checksum; inspect validation errors rather than inventing a corrected recipient account.
