All of the MICR routing number information is required for a check or draft to be processed.
To locate your bank routing number, look between the transit symbols, as shown in the "Routing Number" graphic above.
The routing number is always 9-digits on a U.S. check. The routing number is also know as the transit number, the ABA number, the RTN.
For the account number, you can locate this directly after the routing number. The example above has the account number terminated by the ON US Symbol ||'. Once you locate the account number, be sure to enter all leading zeros. Some customers who give check by phone payment or enter the routing number and account number online will enter the account number from memory, and not from the check. This can cause problems in processing a draft. If the customers check says the account number is 000025642, the customer may say or enter just the 25642 part of the number - it is important to ask if there are any leading zeros, especially if the account number seems short. Most account numbers are 8-14 characters.
