ktoblzcheck - Check Account and BLZ (bank routing code)


ktoblzcheck [--returncode] [--file=<datafile>] <bank-id> <account-id>


This manual page documents briefly the ktoblzcheck application.

ktoblzcheck is a program that will check a given account and blz for the bank being valid and the account being valid using some checksum calculations, if supported for that particular bank. The output is the clear-text name of the bank specified by <bank-id>, and whether the given <account-id> is a valid account number at this bank.


This is the Bankleitzahl (bank routing id), actually it is the account-id of that particular bank at the Deutsche Bundesbank.
This is the account number you wish to verify. If the checksum method of the bank specified by the <bank-id> is supported, you will get the account-id verified, i.e. if it is a valid account-id at that particular bank.
If given, the result is returned via the returncode and no output on the terminal. The following returncodes are possible: 0: account and bank are ok 1: unknown, e.g. checksum not implemented or such 2: account and/or bank not ok 3: bank not found
Specifies the file with the bankdata. This file can be obtained via the internet from the Deutsche Bundesbank on address
Beware! This page is in German only.


No bugs are known at this time. Only certain checksum algorythms are supported as of now, so please don't complain if you always get "unknown" as return value.
