Installation

$ gem install blz

Command line tools

I provided a command line tool to search for BLZ:

blz exact 70150000

70150000, Stadtsparkasse München, 80791 München, SSKMDEMMXXX

Or search for BIC matches:

blz bic SSKMDE

70150000, Stadtsparkasse München, 80791 München, SSKMDEMMXXX

Or use substring matches:

blz match 4945

49450120, Sparkasse Herford, 32045 Herford, WLAHDE44XXX
49450120, Sparkasse Herford, 32285 Rödinghausen, Westf
49450120, Sparkasse Herford, 32132 Spenge
49450120, Sparkasse Herford, 32269 Kirchlengern
49450120, Sparkasse Herford, 32122 Enger, Westf

49450120, Sparkasse Herford, 32221 Bünde
49450120, Sparkasse Herford, 32556 Löhne
49451210, Sparkasse Bad Salzuflen -alt-, 32102 Bad Salzuflen, WELADED1BSU

Or find by city (rather uncommon, but useful):

blz city Münstereifel

37069627, Raiffeisenbank Rheinbach Voreifel, 53902 Bad Münstereifel
37070024, Deutsche Bank Privat und Geschäftskunden, 53902 Bad Münstereifel, DEUTDEDB379

Downloads

You can download the current list of BLZ (free of charge) from the German Bundesbank.

The Bundesbank releases a new list every three months. The last part of the version number of this gem mirrors the last date the provided data is valid.

Now go and build your own BLZ gem ;-)
