Why Sparkasse and Volksbank don’t have one unified Bank IDs?

Although Sparkasse and Volksbank look like single nationwide banks, they are actually networks of hundreds of legally independent local banks. Each local institution has its own banking license, balance sheet, IT system, and regulatory responsibilities. Because of this structure, they must use separate Bank IDs (BLZ/BIC/IBAN ranges).

Key points:

• Legally separate entities: Every local Sparkasse/Volksbank is its own bank, not a branch.

• Different IT and payment systems: Many use different cores, processing setups, and instant-payment capabilities.

• Routing requirements: Payment networks need unique identifiers to route transactions correctly.

• Decentralized governance: Each bank has its own management and risk rules, so one unified ID would not work.

In practice, these groups operate under a shared brand but function as many small banks, which explains the fragmentation in Bank IDs - and why no provider like Ivy can change or unify this.
