Format of ABA RTN in the USA
There are two forms of ABA RTN, namely, fraction form and the MICR form. The fraction form is no longer used but still kept as a backup in case of MICR failure for the manual processing of the cheques. The fraction form appears on the top of the cheque in the upper right part adjacent to the date.
Let’s assume that the fraction form is CC-AAAA/BBBB. Here the BB represents the center location of the bank checking process but is no longer used yet printed. AAAA represents the ABA Institution Identifier and BBBB represents the Federal Reserve Routing Symbol.
Let us assume the MICR form is BBBBAAAAC. Here the AAAA represents the ABA Institution Identifier and BBBB represents the Federal Reserve Routing Symbol just as it was in case of ABA RTN but in reversed position. C represents the check digit.
