What's A Routing Transit Number:
Each United States operating bank or depository institution has it's own transit number or "routing number". It is a nine digit code, which identifies the issuing bank for check sorting, funding, wire transfers and ACH transactions (debits/credits). You see them as those funny looking numbers on the bottom edge of a check or treasury warrant. That funny type font is usually printed in magnetic ink and is read by a magnetic ink character reader, called a "MICR." Today, newer technology can read them optically with an optical character reader (OCR), which has reduced the requirement of magnetic ink.
This code was originated by the American Bankers Association (ABA) in 1911, and they remain the numbering assignment authority today. For years, the number has been publically referred to as the ABA Number®, which is a trademark of the ABA. More commonly though is referred to as an "RTN" or routing number.
Before the advent of MICR machines in the late 1950's, all checks had the fractional format (XX-XX/XXXX). Oftentimes, these fractional codes are what people write on their deposit slips. These numbers can be converted via an algorithm into their 9-digit equivalent. FindRoutingNumbers.com has a convenient tool to convert fractional routing numbers, see Understanding and Converting Fractional Routing Numbers.
