Best banks and credit unions in Idaho 2026

Every bank with a branch in Idaho

29 FDIC-insured banks run 389 full-service offices in Idaho. 11 of them are community banks, and 4 operate nowhere else. This is the federal record: every figure below is the regulator's own.

Deposits by office come from the FDIC Summary of Deposits, counted each 30 June; the leverage ratio is capital as a share of assets, from each bank's latest Call Report. Nothing here is blended into a score. Search by ZIP to see the offices nearest you.

Every credit union with an office in Idaho

40 federally insured credit unions run 262 offices in Idaho, between them serving 8,638,604 members. 32 carry the NCUA's low-income designation. Figures are from each credit union's own NCUA Call Report.

A credit union is measured differently from a bank and the numbers are not interchangeable: the net worth ratio here is the NCUA's capital measure under 12 CFR 702, where 7% is well capitalised, and shares are the credit union equivalent of deposits. Membership usually turns on where you live or work, so a local credit union is often open to you even when its name suggests otherwise.

What makes a Idaho bank account worth opening

Look at four things in order: the APY (does it beat the FDIC national average of about 0.60%?), the monthly fee (anything above $0 should come with a clear waiver path), the minimum opening deposit, and the membership rule for credit unions. Idaho residents typically qualify for at least one large state-chartered credit union on residency alone, and that credit union is often the highest-APY option available locally.

Is my money safe at a Idaho bank or credit union?

Yes, if the institution is federally insured. FDIC covers banks up to $250,000 per depositor, per ownership category; NCUA covers credit unions at the same limits. Every institution in this directory carries one of those insurances — the FDIC or NCUA ID is listed on the full provider row.
