is transit number the same as routing
Routing/Transit Number. The first number listed on the bottom of your checks is a routing number, also called a bank number or transit number. A bank/transit number identifies your bank so when an institution receives a check it knows the institution to which it belongs. Routing numbers are always nine digits and assigned by the American Banking Association. A bank might have one transit number for all accounts, or a different transit number for each type of transaction, such as one for paper checks and one for electronic transfers.
