Can Routing Numbers Change?

Note that Routing Numbers do occasionally change, but it’s rare. For example, if two banks merged or if a bank is acquired by another bank or financial institution, your routing number could change. You should be given notice of the change with time to make adjustments if you are a verified account holder.

Be sure to confirm your Routing Numbers with your bank (or credit union or other financial institution) before any transaction if your bank has recently been acquired or has merged with another bank.

What Kinds of Banks have Routing Numbers?

All federally-chartered and state-chartered banks and institutions in the United States that are qualified for an account at a Federal Reserve Bank have Routing Numbers (that are issued by the American Bankers Association or ABA). The ABA assigns unique bank routing numbers, so there’s no risk of errors or duplication between banks.

There are approximately 28,000 current active Routing Numbers.*

What do Routing Numbers Stand For?

The first four digits: the Federal Reserve Bank of the district where the bank or institution is located

The next four digits: the unique number that represents the bank or institution

The last digit: the check or instrument as a mathematical calculation to prevent check fraud

Are Routing Numbers Safe?

Routing Numbers are public knowledge, so they are information that anyone can get or have, legally. The only time it is unsafe for someone to have your bank’s Routing Number is when they ALSO have your checking account number. By impersonating you and having both your Routing Number AND your bank account number, they could potentially set up Bill Pay, ACH transactions, or other automatic payment using your funds.

Most institutions and retailers have fail-safe, fail proof methods for verifying and double checking that you are actually you when you set up auto payments. For example, legally, you have to authorize an ACH transaction that goes in or back out of your bank account.

ACH Fraud

ACH fraud is usually directed toward larger, commercial bank accounts, not individual or personal ones. However, DO NOT give out your account number to anyone (via email or in person) unless you can verify that the person is a legitimate representative.


ACH withdrawals from your account should only be authorized via the secure webpage of a company or institution. Alternatively, you can authorize ACH withdrawals via written letter.
