How is a credit union different from a bank? A credit union exists to serve a community of members — not to maximize corporate profits. When you join SACU, you become part of a strong financial cooperative.

How To Join SACU

Since SACU is a collective, you qualify for membership based on your affiliations — there are many from which to choose. For example, you can qualify for membership based on where you work, live or worship.

Think about which of the following affiliations you may have, and be ready to indicate them on your application. To make it easy, we've organized them into three groups: immediate family, San Antonio area, and Houston area affiliations.

Immediate Family Affiliations
  • Someone in your immediate family is a member of SACU (spouse, child, sibling, parent, grandparent, grandchild, stepparents, stepchildren, stepsiblings, and adoptive relationships)
San Antonio Area Affiliations
  • Live, work or worship in West or South San Antonio
  • Work for or are a member of one of our Select Groups
  • Are a student of higher education
  • Volunteer for a United Way agency
  • Active or retired military
  • Military dependent
Houston Area Affiliations
  • Work for or are a member of one of our Select Groups
  • Are a registered Catholic with the Archdiocese of Galveston-Houston
