The city of Goodyear is investigating a possible compromise of its online bill payment system.
City officials say the issue was discovered on Monday morning when a customer reported a potential problem.
The system was disabled and the system's vendor was made aware of the problem.
Officials say Goodyear residents were notified by the city's social media platforms.
Residents can safely make utility payments by postal mail and checks issued using an online banking system or through Goodyear's automated phone system at 623-882-7373.
According to city officials, it will take several days to figure out the extent and type of breach and how many residents were affected.
The city says it will be in contact with any resident whose information could have been compromised.
City Manager Julie Arendall released the following statement:
“The most important thing our residents need to know is this: if you use the city’s online utility bill payment system or made an in-person payment using a debit or credit card, please check your credit card account as soon as you can. If you see anything that looks suspicious, please contact your credit card issuer right away.”
