What if a check you have received has no identifying bank name? There is a way to look it up under its routing transit number. This is a nine digit bank code used in the United States that is on the bottom left side of a check. From Wikipedia, “The RTN (routing transit number) is also used by Federal Reserve Banks to process Fedwire funds transfers, and by the Automated Clearing House to process direct deposits, bill payments, and other such automated transfers.” This can also be called the ABA number, or the American Banking Association number.
From the website, “The Automated Clearing House, commonly called ACH, is a network of financial institutions that carry out 98% of the electronic transactions in the United States.” The Automated Clearing House website provides a way to look up routing transit numbers to find out where a check or fund transfer came from. Just type in the nine digit code into the search box. The website will then list the bank, along with its address. If you then click on “browse listings” at the bottom of the webpage, a list of institutions will come up. Click on the first letter of the institution to bring it up and get its ACH services phone number.
