Ally Bank Routing Number: One Number, Every Account

What is the Ally Bank routing number?

Ally Bank's routing number is 124003116. Unlike traditional banks that assign different routing numbers by state, Ally uses one number for every customer regardless of location. Without legacy branch networks from acquisitions, there's no patchwork of inherited routing numbers to maintain. The 12 prefix ties to the Federal Reserve Bank of San Francisco's Salt Lake City processing center, reflecting Ally's Utah charter.

Ally was originally founded as GMAC Bank — the banking arm of General Motors' financing division — and rebranded as Ally in 2010, consolidating its banking operations under a single Utah-based charter in the process.

Using routing number 124003116

124003116 works for all Ally Bank transaction types: ACH transfers, direct deposit, bill pay, and domestic wire transfers. This applies to Ally checking accounts, savings accounts, money market accounts, and CDs. When setting up direct deposit or autopay, there's no guesswork — it's always 124003116.

Wire transfers

For domestic wire transfers, use the same routing number. Ally's SWIFT code for incoming international wires is ALBIUS44. Outgoing domestic wires cost $20 — lower than most traditional banks — and incoming wires are free. International outgoing wires are not supported directly through Ally; customers needing to send international wires must use a third-party service. All wire transfers must be initiated through Ally's online banking platform or mobile app.

Where to find your routing number

In the Ally mobile app, tap your account and view account details. On Ally's website, navigate to your account and the routing number is displayed under account information. Since Ally doesn't issue paper checks for savings accounts, the app and website are the primary methods for confirming the number. Ally checking accounts include an optional checkbook where the routing number prints in the standard bottom-left position.
