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.
  • Counties get a page only when at least one credit union's record names them, so this list covers St. Louis County as the source documents describe it.
  • 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.
