What Is a Routing Number?

A routing number (also known as an ABA number or transit number) is a unique nine-digit code assigned to financial institutions in the United States. It acts like a bank’s “address” in the digital payment system, telling other institutions exactly where to send or receive funds.

Routing numbers were first introduced by the American Bankers Association (ABA) in 1910 to streamline check processing. Today, they are essential for electronic transactions such as:

Direct deposits (payroll, government benefits)
ACH transfers (bill payments, peer-to-peer transfers)
Wire transfers (domestic and international)
Check processing

Structure of a Routing Number

Each routing number is carefully structured to prevent errors:

First 4 digits: Federal Reserve routing symbol.
- The first 2 digits indicate the Federal Reserve district (out of 12).
Next 4 digits: Identify the specific financial institution.
Final digit: A check digit used to verify the number’s validity.

Example: 123456789

“12” → Federal Reserve district
“3456” → Bank identifier
“9” → Check digit

This nine-digit code ensures your money gets to the right place, safely and efficiently.
