In the United States, all banks have a tracking number, more commonly known as a routing transit number, which helps to make the transfer of money between banks simpler. Routing numbers were started by the American Bankers Association in 1910. All transit numbers are nine-digit numbers that identify your bank when someone cashes or deposits a check you wrote or when you wish to receive an ACH transfer or direct deposit. The number is printed on the check and easy to spot.
Look for the symbol that resembles "|:" on the bottom left corner of a check. Be sure that you're looking at a check and not a deposit slip, which are sometimes included in the back of a checkbook.

Look to the right of the "|:" symbol. There will be a string of nine digits. That is the routing or transit number. At the end of the string of digits will be another "|:" symbol to let you know that the routing number is finished.
Look along the bottom of the check if the nine-digit number is not in the left corner. Some banks print the number in the middle of the bottom. It will always be between two "|:" symbols.
