BANK_TRANSIT_CODE is a mandatory 16-character alphanumeric field which stores the banking transit number which uniquely identifies the branch within the banking system. 

The numbers located on the bottom of your check is called a [MICR|MICR FORMAT] line. The [MICR|MICR_FORMATTING] line is an acronym for Magnetic Image Character Recognition.

For Canadian Installations: The transit # is the format of ddddddddd where the first 4 digits identify the bank transit, while the last 5 digits identify the branch transit. 

For American Installations: The [MICR|MICR_FORMATTING] line consists of three elements; a routing transit number (also known as an [ABA|ABA_NUMBER] number or bank fraction number), an account number, and the check number.

The ABA number consists of three elements: 
*3 character bank transit
*5 character branch transit 
*1 character check digit.
