How to join a credit union in Texas
To join one of the credit unions above, you need to fall within its field of membership — usually by living or working in San Antonio or the surrounding area, through your employer, or via an association anyone can join. Once eligible, you open a small share account (often $5) that makes you a part-owner with one vote, regardless of your balance. Deposits are insured up to $250,000 by the NCUA.
Credit unions in San Antonio — common questions

The second list adds 6 more credit unions headquartered elsewhere that NCUA shows with a branch in San Antonio, as of June 30, 2026. A credit union can serve a wider area than its branches. For a true distance-sorted list from your exact location, use the "near me" finder above.
Can I join any credit union in San Antonio?
Not always. Every credit union has a "field of membership" — you typically qualify by living or working in a defined area, your employer, or an association you can join. Many community credit unions in Texas accept anyone in the area; others are tied to a specific group. Check each credit union's eligibility before opening a share account (often as little as $5).
Credit union vs bank — which is better in San Antonio?
Banks are for-profit and owned by shareholders; credit unions are not-for-profit cooperatives owned by their members, so surplus comes back to members as higher savings rates, lower loan rates and fewer fees. The trade-off is membership eligibility and, sometimes, a smaller branch and ATM network.
