Routing/Wiring Instructions
GNB Bank customers will be required to have a routing number or routing transit number is a 9 digit number that identifies a financial institution in a transaction and the location where your bank account was opened. The most common types of transactions are ACH and wire transfers. You’ll often be asked for your checking account routing number when you’re making a payment online or by phone.
Some banks and financial institutions usually have multiple routing numbers serving different purposes, geographical regions, and branches. Therefore it is important to ensure that you are using the correct routing number before you initiate a money transfer.
A routing number can also be referred to as an RTN, a routing transit number, or an ABA routing number and can be easily be found printed on the bottom of a check or in the online banking portals of the financial institutions.
How to Find Your Routing Numbers on Check
The best way to find the routing number for your Marquette Bank checking, savings, or business account is to look into the lower-left corner of the bank check.
