IBAN Checker

Version 1.0   11 May 2015

Summary

IBAN Checker is a simple program which checks the format and checksum of an IBAN
number.

Instructions

When the program is started, it looks like this:



Enter an IBAN number, then press the return (or enter) key.

If the format of the number is correct for the country indicated by the first
two letters and its checksum is also correct, that is reported.

If the format of the IBAN number is incorrect or the checksum test fails, that
is reported.

You should NEVER attempt to correct an IBAN. If the IBAN check fails, you should
ask the account holder for the correct IBAN. Correcting the check digits does
NOT mean that the resulting number is a valid IBAN.

Note that only an account holder's bank is authorised to create an IBAN. Do not
attempt to construct an IBAN yourself - such a number may be invalid, even if it
passes the tests performed by this program.

Credits

The IBAN data used in this IBAN Checker is derived from data in the ISO13616
IBAN Registry which is maintained by SWIFT.
