How this list is built, and what it does not tell you

  • Every entry comes from a credit union's own published membership page or its public charter record. Each row carries the source URL, the date it was read, and a confidence score.
  • A credit union whose record names specific counties appears only for those counties. One with no county detail is listed as serving the whole state — absence of county detail is never read as exclusion.
  • Membership eligibility records exist for about 83% of tracked credit unions. A credit union missing from this page may still serve the area; it is not evidence of ineligibility.
  • A county appears above only when at least one credit union record names it. A county with no page can still be served by the 35 statewide credit unions listed here.
  • Verification method: eligibility methodology. Programmatic access: membership eligibility API.
  • Membership eligibility is guidance based on public charter data and institution websites; final determination is made by the institution.
