Become a Member

Thank you for your interest in joining Infinity Federal Credit Union (FCU). Whether you become a familiar face at one of our four convenient branches in Westbrook, Portland, Bangor, or Arundel, or you prefer to access your accounts online, you will be a member of our family.

As a member of a credit union, you will be part of a unique not-for-profit financial cooperative. Which means your money stays local, helping build a stronger community for you, your neighbors, and local businesses. Founded in 1921, as Maine’s first credit union, we were the pioneers in the industry paving the way. While a lot has changed in 96 years, our commitment to you, as our member, has not wavered. Today, we continue to challenge the status quo and do banking differently to keep you a step ahead in life.

Who Can Join

You qualify for membership at Infinity FCU if you live, work, worship or attend school in Cumberland and York Counties, and in the City of Bangor, Maine. In addition, immediate family or household members of current Infinity FCU members may also qualify for membership.

How to Join

You retain your membership with Infinity FCU by maintaining $5 in a Regular Share (Savings) Account. Your $5 initial deposit is your "share" of ownership in the credit union. Once you are a member, you can take advantage of our full array of financial services.

Important Information about Procedures for Opening a New Account - To help the government fight the funding of terrorism and money laundering activities, federal law requires all financial institutions to obtain, verify, and record information that identifies each person who opens an account. What this means for you: when you open an account, we will ask for your name, address, date of birth, and other information that will allow us to identify you. We will also ask to see your driver's license or other identifying documents.


Opening Youth Accounts:
