During the transition, you may receive a statement from both 1st Bank Yuma and OneAZ for the same statement period.

If you had OneAZ accounts prior to September 2026, you will have both historical statements available up to 24 months.
If you're having trouble changing your debit card PIN, first make sure you're calling from the phone number registered to your account.
If you're still unable to change your PIN, you may visit a OneAZ Yuma branch, where an associate can help escalate your request to the appropriate team for assistance.
We apologize for any inconvenience and appreciate your patience.
