What Is an Aba Number?

An ABA number is what many refer to as a routing number, a nine-digit unique identifier for a financial institution in the United States. ABA standards for the American Bankers Association, which is the body issuing these numbers for bank identification. 

ABA numbers are used to facilitate bank transactions, including sending electronic transfers between bank accounts, direct deposits, check processing, and fund transfers in general.

In other words, ABA numbers are the plumbing of the US banking system, offering financial routing for transfers between banks around the country. In fact, the only thing an ABA number cannot do is account identification, which is why an account number is also required when sending a transfer.
