Routing Transit Number (RTN)

A routing transit number (RTN) is a nine-digit code that identifies a financial institution. It is also known as a routing number, bank routing number, or ABA routing number. The RTN is used to route funds between financial institutions when processing electronic payments, such as checks, ACH transfers, and wire transfers.

The first two digits of the RTN identify the Federal Reserve Bank that the financial institution is affiliated with. The next four digits identify the financial institution itself. The last three digits are a check digit, which is used to verify the accuracy of the RTN.

RTNs are assigned by the American Bankers Association (ABA). You can find your financial institution's RTN on your checks, bank statements, or by contacting your bank.

Here are some additional details about RTNs:

* RTNs are used for both domestic and international payments.
* RTNs are not the same as account numbers.
* RTNs are not case-sensitive.
* You can use an RTN to verify that a check is legitimate.

If you are ever unsure about an RTN, you can contact the financial institution that issued the check or the ABA.
