There are several ways to qualify for membership with First Service. If you meet the eligibility requirements, you can become a member by opening a primary savings account with as little as $5.00.

All members are required to have a primary savings account. This establishes member-ownership in the credit union. You can also add additional checking or savings accounts at any time.

An important part of our identity verification procedures is to compare your address, date of birth, and other facts to the information contained in your credit report. It is a "soft pull" and will not affect your credit score.

Under the requirements of the Patriot Act, credit unions must have effective procedures for:

  • Verifying the identity of any person seeking to open an account, to the extent reasonable and practicable
  • Maintaining records of the information used to verify the person’s identity, including name, address, and other identifying information.

Please call us at (713) 676-7777 if you have any additional questions.
