Formerly the Idaho Falls Teachers Credit Union, A+ was originally established to serve educators in the Idaho Falls area. Mountain America dates back to 1934, when it was originally the Salt Lake Telephone Employees Credit Union. It changed its name to Mountain America after merging with Postal Workers Credit Union in 1984. In 1988, Mountain America merged with Utah State Credit Union, becoming the second largest credit union in Utah and today it has branches in Utah, Idaho, Nevada, Arizona and New Mexico. It also belongs to an extensive shared branching network as well as several ATM networks, including the CO-OP Network,which allows members to complete surcharge-free transactions at more than 28,000 ATMs nationwide.
A spokeswoman for A+ said the merger will allow their members to enjoy a much wider array of services. The A+ office at 525 Sunnyside Road will remain open.
