Best Banks in Arizona
Top regional banks serving Arizona include:
- National Bank of Arizona
- MidFirst Bank
- Alliance Bank of Arizona
- Pinnacle Bank Arizona
- Western Alliance Bank
The largest bank by presence in Arizona is Chase Bank (approximately 190 branches across Arizona, the most of any bank in the state).
Best for checking: OneAZ Credit Union — no monthly fees, large fee-free ATM network (41,000+), and $350 checking bonus for new accounts
Best for savings: Pibank — 4.40% APY high-yield savings with no minimum deposit and no monthly fees, available to Arizona residents
Regional banks often combine local branch access with competitive accounts, which is why they tend to score well with Arizona customers. Top high-yield savings accounts available to Arizona residents pay around 4.00% to 4.40% (top high-yield savings accounts as of June 2026; FDIC national average is 0.38%) in June 2026.
National Banks Available in Arizona
If you want a big branch and ATM network, the major national banks all operate in Arizona:
- Chase
- Wells Fargo
- Bank of America
- U.S. Bank
National banks are convenient but rarely pay the best savings rates — pair one with a high-yield online account for the best of both.
Best Credit Unions in Arizona
Well-regarded Arizona credit unions include:
- Desert Financial Credit Union
- OneAZ Credit Union
- Arizona Financial Credit Union
- Arizona Central Credit Union
- Copper State Credit Union
Credit unions are member-owned and often beat banks on fees and savings rates, though membership may require living, working, or worshiping in a specific area.

Other Arizona notes: Arizona has a strong credit-union culture — Desert Financial alone has 500,000+ members and $9B+ in assets, making it one of the largest credit unions in the Southwest. National Bank of Arizona (a Zions Bancorporation division) is a major regional player with 57 branches across 44+ communities. Chase dominates branch count (~190 locations). MidFirst Bank ranked highest in J.D. Power’s Southwest U.S. Retail Banking Satisfaction Study. The state regulator (DIFI) oversees state-chartered banks and credit unions but not federally chartered institutions.
Checking, Savings, and CDs Explained
Most Arizona banks offer the same core accounts:
- Checking — for everyday spending and direct deposit. Look for no monthly fee.
- Savings — for your emergency fund. Online banks pay the highest rates.
- Money market — a savings account with limited check-writing.
- CDs — lock money for a set term in exchange for a higher fixed rate.
A common setup for Arizona residents is a no-fee checking account at a local bank plus a high-yield savings account at an online bank.
How Bank Sign-Up Bonuses Work in Arizona
Banks pay cash bonuses — often $100 to $400 — to win new customers. To earn one you typically open a new checking or savings account, then meet a requirement such as receiving a set amount of direct deposit or keeping a minimum balance for a few months. The bonus is usually paid within 90 days. As long as you would open the account anyway, it is essentially free money. We track current offers open to Arizona residents on our listings page.
