Account Number Formats for Wire Transfers
Many international banks require that account numbers be specified in a particular format. See below for details.
CLABE (Clave Bancaria Estandarizada or Standardized Bank Code) is a standard for numbering of bank accounts in Mexico. The CLABE account code has 18 digits, and is a requirement for the sending and receiving of domestic interbank fund transfers.
Canada: Transit Number
Canadian transit (branch) numbers have the following form:
where XXXXX is a Branch Number, and YYY is an Institution Number. The dash between the Branch Number and the Institution Number is an integral part of the code format.
Australia and New Zealand: Bank State Branch
A Bank State Branch code (abbreviated as BSB) is a six-digit code used in Australia that identifies an individual branch of a financial institution.
An almost identical system is used in New Zealand, with a six-digit BSB code, often split into a two-digit "Bank" code and a four-digit "Branch" code. However, the New Zealand and Australian systems are incompatible.
Various Countries: IBAN and SWIFT
The International Bank Account Number (IBAN) is an international standard for identifying bank accounts across national borders with a minimal risk of propagating transcription errors. An 8 or 11-character SWIFT code is required in conjunction with the IBAN.
