As of 2015, the Teachers Credit Union's operations are done through branches that are located around the state of Indiana and the southwestern region of Michigan. The TCU is the largest credit union in the state of Indiana and controls over $2 billion in assets. The credit union's services include both personal and business financial services, such as checking accounts, savings accounts, investment services, mortgage loans and various other types of loans.
The Teachers Credit Union website contains a branch locator tool that accurately displays all of the credit union's branches. The tool also includes a search function that uses an address, city or ZIP code as a search variable to locate a nearby branch. TCU customers can also use the tool to find any CO-OP shared branches or surcharge-free ATMs in the area. Each branch is listed on the tool with its address and contact number.
The Teachers Credit Union was established by a group of teachers who collected their savings together to start a credit lending service between themselves. The credit union also operates a Treasure Chest Club program that is designed to provide financial services to children under the age of 12 in addition to its routine financial support for existing members.
