Santander Bank Routing Numbers by State
Santander Bank uses different routing numbers based on the state where you originally opened your account and, in some cases, the date you opened it. This complexity stems from Santander's acquisition of Sovereign Bank and the consolidation of regional banking operations. Here are all the routing numbers organized by state:
Connecticut:
- Account Opened After May 17, 2012: 011075150
- Account Opened Before May 17, 2012: 011401533
Delaware:
- All Accounts: 031318707
Florida:
- All Accounts: 067014822
Massachusetts:

- Account Opened Before May 17, 2012: 011401533
New Hampshire:

Important Note About Account Numbers:
Santander Bank uses your account number to determine which routing number applies to your account:
- If your account number has 11 digits, use routing number: 011075150
- If your account number has 10 digits, use routing number: 231372691
This dual routing number system exists because Santander Bank integrated multiple legacy systems during its expansion and acquisitions throughout the Northeast.
