Switch from a big bank to a credit union

Credit unions are member-owned cooperatives. Many people leave big banks for clearer local service — but membership is not automatic. This page is a practical checklist for switching after you confirm a published join path. It is not financial advice, not a rate ranking, and not a promise of approval.

Joinable only paraphrases published field-of-membership (FOM) and fee facts from credit-union sites (and NCUA materials when relevant). We never invent eligibility, fees, or ATM counts. Always re-check the CU’s membership page before you apply.
Not a guarantee: Matching a published join path does not mean you will be approved. Credit unions still verify identity (CIP) and apply their own account rules.

1. Start with “who can join,” not with rates

Banks generally take any eligible customer. Credit unions are limited by a field of membership — for example live/work/worship/school in a county or state, or a documented association path. If you skip FOM and chase APYs, you may waste time on a CU you cannot join.

2. Prefer published Easy paths when you’re switching under time pressure

Easy on Joinable usually means a county-wide or statewide live/work/worship/school path, or a free/no-cost association path the CU publishes. Medium often means city lists, “portions of” counties, ZIP/census nuance, or a small published donation.

Examples of association-style paths that appear on Joinable listings (always confirm current terms on the CU site):

Association paths are still subject to CU approval and CIP. They are not “open to the world without paperwork.”

3. Switching checklist (order that usually hurts less)

  1. Confirm FOM on the CU’s own membership page (and Joinable sources).
  2. Open the membership share / savings with the published minimum (often $1–$25). Keep that share open — it is usually what makes you a member-owner.
  3. Open checking if you need it for direct deposit; read the published fee schedule for monthly fees, paper statements, and ATM rules.
  4. Move direct deposit (payroll / benefits) once the new account and routing number work.
  5. Move autopays one at a time; keep the old bank funded until the last one clears.
  6. Update linked apps (Venmo, PayPal, brokerages) to the new routing/account.
  7. Close or idle the old account only after outstanding checks and ACH have cleared — follow your old bank’s close process.

4. ATMs: read the network name, not just “fee-free”

Many CUs advertise CO-OP, Allpoint, MoneyPass, or similar networks. “Fee-free” usually means no surcharge from that network / no CU fee at in-network machines — the machine owner or a foreign ATM fee line on the CU’s schedule can still apply out of network. Joinable listings cite network names and schedule dollars only when published; otherwise we say not published.

5. Insurance: prefer NCUA, read ASI caveats loudly

Most Joinable seed listings are NCUA / NCUSIF insured (confirm via the NCUA locator). A few publish ASI (American Share Insurance) instead of or in addition to NCUA. ASI is private insurance — not the federal NCUSIF. When a listing is ASI-only or NCUA+excess ASI, Joinable puts a loud caveat on the card. Do not treat private excess coverage as interchangeable with federal insurance.

6. Why Joinable exists next to the NCUA locator

The NCUA locator is excellent for branch pins and insured status. It does not explain join difficulty in plain language. Joinable’s job is the membership last mile — with citations. See also How we vet.
