Comerica Bank routing number

If you’re a Comerica Bank customer, you’ll probably need to know your routing number at some point. Routing numbers are an important element of banking, because they’re used to identify different banks in different types of transactions.

Because Comerica has locations in multiple states, not every customer at the bank will have the same routing number. Keep reading to learn which Comerica Bank routing number you’ll need to use, and how it can come in handy.

What Is a Routing Number?

Routing numbers are nine-digit identification codes used by banks during transactions such as wire transfers and online payments. The American Bankers Association established the routing number system back in 1910.

Routing numbers were originally designed to identify one processing point for checks, but today they’re also used in automated clearinghouses, electronic funds transfers and online banking transactions.

Can Banks Have Multiple Routing Numbers?

As Comerica shows, banks can have more than one routing number. Large national banks such as Wells Fargo, Citi® and Bank of America have dozens of routing numbers between them. Banks might have multiple routing numbers due to size, geographic reach and mergers.

Most banks also provide their routing numbers through your online account.

What Is the Routing Number for International Wire Transfers?

When you transfer funds using a bank outside the U.S., you’ll use a SWIFT code instead of a routing number. Here’s the SWIFT code for Comerica:
