BLz

BLZ is a three-letter abbreviation that can refer to several different things depending on the context. In international standard identifiers, BLZ designates Belize as the ISO 3166-1 alpha-3 country code.

In German-speaking banking contexts, BLZ stands for Bankleitzahl, the bank code used to identify financial institutions in domestic payments. In Germany, the Bankleitzahl is eight digits long and is used to route payments within the national clearing system. With the adoption of international formats such as IBAN, the BLZ remains the bank identifier component for German accounts and is used alongside the account number in many transfer schemes.

Beyond these, the acronym BLZ may appear in other domains as an abbreviation for organization names, product codes, or project titles. In such cases, its meaning is specific to the field or organization involved, and clarification from the relevant source is required.
