The [[wp:International_Bank_Account_Number|International Bank Account Number (IBAN)]] is an internationally agreed means of identifying bank accounts across national borders with a reduced risk of propagating [[wp:Transcription_error|transcription errors]].
|
|
|
|
The IBAN consists of up to '''34''' alphanumeric characters:
|
|
::* first the two-letter ISO 3166-1 alpha-2 country code,
|
|
::* then two check digits, and
|
|
::* finally a country-specific Basic Bank Account Number (BBAN).
|
|
|
|
|
|
The check digits enable a sanity check of the bank account number to confirm its integrity even before submitting a transaction.
|
|
|
|
|
|
;Task:
|
|
Validate the following fictitious IBAN: <tt> GB82 WEST 1234 5698 7654 32 </tt>
