Routing number lookup

Check a 9-digit ABA routing number and see which bank it belongs to. Every record is labeled bank-verified, cross-checked, or unconfirmed.

Checking a whole list? Use the bulk routing number checker.

Spaces and dashes are fine — we strip them, check the ABA checksum, then find the bank.
