Credit union vs bank

A credit union is a member-owned, not-for-profit cooperative; a bank is a for-profit corporation owned by shareholders. The practical difference for you is membership: credit unions limit who can join via a published field of membership, while banks generally take any eligible customer.

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.

Ownership and purpose

Credit unions return earnings to members through dividends, lower loan rates, or fewer fees — when their boards choose to. Banks distribute profits to shareholders. Neither structure automatically means “better rates” for you; Joinable does not rank money products.

Who can join

Banks typically accept anyone who meets ID and account rules. Credit unions must stay inside a field of membership (live/work/worship/school in a geography, an employer group, or a published association path). See What is field of membership and membership requirements.

Deposit insurance

Most Joinable listings are NCUA / NCUSIF insured (federal). Banks use FDIC. A few CUs use private ASI — see NCUA vs ASI and Is my money safe.
