Credit Unions & BankingView details →Locations are a credit union's NCUA charter (headquarters), geocoded to the city — not its individual branches. A listing here means a credit union is based in or near San Antonio, not that it is the nearest branch to you.
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.

This page lists credit unions whose NCUA charter (headquarters) is based in or near San Antonio — geocoded to the city, not to individual branches. A credit union based elsewhere may still have a branch near you, and one based here may serve a wider area. For a true distance-sorted list from your exact location, use the "near me" finder above.
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).
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.
