What is a credit union?

A credit union is a member-owned, not-for-profit financial cooperative. Members pool savings and borrow from that pool; earnings stay with the membership rather than outside shareholders. You usually must match a published field of membership before you can open accounts.

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. This page is educational — not financial advice.

Plain-language definition

Think of a credit union as a bank-like place to hold checking and savings, take loans, and use cards — but structured as a cooperative. When you join, you become a member-owner (typically by opening a small membership share/savings). You are not buying stock in a for-profit company; you are joining an institution that serves people who share a defined membership bond.

Who owns it

Members own the credit union. A volunteer board (elected by members in many charters) sets policy; management runs day-to-day operations. Surplus may return to members as dividends, lower loan rates, or fewer fees — when the board chooses. That ownership story is why people contrast credit unions with banks; for a side-by-side, see Credit union vs bank.

How they differ from banks (practical)

Membership gate — Banks generally take any eligible customer. Credit unions must stay inside a published FOM (geography, employer group, association, or family path).
Purpose — Cooperative service to members vs shareholder profit. Neither structure automatically means better rates for you; Joinable does not rank APYs or loans.
Insurance brand — Most federally insured CUs use NCUA/NCUSIF; banks use FDIC. A few CUs use private ASI — not the same as federal coverage.

Who can join

Eligibility is the field of membership: live, work, worship, or attend school in named counties; belong to a listed employer or group; join through a published association; or qualify as a relative of a member. Joinable paraphrases those published rules and labels paths Easy, Medium, or Hard — see also membership requirements and credit unions anyone can join.

How joining usually works

Confirm you match a published path, apply with ID and taxpayer ID, fund the membership share account at the CU’s published minimum, then add checking if you need it. Step-by-step: How to join a credit union. Moving payroll carefully: without missing a paycheck and switch from a big bank.

Are deposits insured?

At most U.S. credit unions, shares are federally insured by the NCUA through the NCUSIF (commonly described as up to at least $250,000 per insured ownership category). Confirm insurance on the CU and via the NCUA locator. Private ASI is different — read Is my money safe in a credit union? and NCUA vs ASI.

Find one you can actually join

Joinable’s job is the last mile the branch map does not answer: who can join from your county, how hard the published path looks, and what fees or ATM notes the CU has published — with sources and last-verified dates.
