San Antonio
Credit unions whose published field of membership covers common Greater San Antonio paths — live, work, worship, school, or business in Bexar and nearby counties (Comal, Guadalupe, Medina, and others when published), or broader Texas / free TXCC when published. We paraphrase official FOM — not a claim that every CU covers every San Antonio ZIP.

Also noted (not full Easy/Medium recommendations)
- Randolph-Brooks (RBFCU) — large SA/Austin presence; official FAQ emphasizes many SEG/neighborhood ways rather than a simple published county checklist this pass — not listed as Easy community FOM here.
- Soarion — mapped portions of Bexar + military / Airman Heritage Foundation paths — address-specific; omitted from the short Easy list.
- TDECU / Texans / Firstmark TXCC — free Texas Consumer Council association paths for Texas residents (labeled on listings).
- Occupational / employer affinity CUs without a community path → Hard for the general public.
