MICR encodes two very important numbers on the bottom of a check: the American Banker's Association (ABA) routing number and an account number. The ABA routing number, sometimes called an ABA number or just a routing number, uses a combination of codes to indicate the institution where the check was issued. The code, which always totals nine digits, expresses a unique identifier composed of a four-digit Federal Reserve routing symbol, a four-digit ABA institution number and a single check digit. The second set of numbers printed on the bottom of the check represents the bank account number of the associated checking account.
