How Do You Find the Money Transfer Number of Your Bank?

The money transfer number of a bank, or routing number, is the nine-digit sequence of numbers located at the bottom left hand corner of a customer's check or deposit slip, explains Regions Bank. Customer service representatives can provide the routing number, according to Bank of America. A customer can also obtain the number by signing on to online banking under his account's information and services tab. Banks use different routing numbers in each state.

The American Bankers Association assigns a routing number to each bank for identification purposes, explains Bank of America. Another name for the ABA routing number is "routing transit number." Where customers open their accounts and the type of transactions they conduct determine which routing numbers customers should use. Transaction types include electronic transactions, such as receiving wages or federal tax refunds, and wire transfers, such as receiving domestic or international funds. Paper transactions, such as ordering checks, may require different routing numbers.

Texas, Florida, Illinois and Michigan are among the states that have multiple ABA routing numbers, notes Bank of America. Routing numbers are different from the Society for Worldwide Interbank Financial Telecommunication code, which is a unique identification code that some banks may require when wiring funds internationally.
