In Online Banking, select the OneAZ account the check was drawn from. Next, select the three dots and select Stop Payment. Enter the requested information then select Continue. Review and accept the terms and disclosures and select Submit. A stop payment can take up to three business days to process and is stored in our system for six months. For assistance with your stop payment request, please schedule an appointment to meet in-person or virtually with a personal banker at your local OneAZ branch or contact our Member Care Center.
