Arizona Data Breach Notification Law
A.R.S. § 18-552
Arizona's data breach notification law (A.R.S. § 18-552) was updated in 2018 to require notification within 45 days of determining a breach occurred. If more than 500 Arizona residents are affected, the company must also notify the AG. The law covers a wide range of personal information including medical information, passport numbers, individual taxpayer identification numbers, unique biometric data, and online account login credentials — a broader definition than many states.
What This Law Covers
Arizona's breach notification law requires businesses and government agencies that maintain personal information about Arizona residents to notify affected individuals when that information is subject to unauthorized access or acquisition. "Personal information" typically includes Social Security numbers, driver's license numbers, financial account numbers, and in many states has been expanded to cover medical data, biometric data, online credentials, and tax IDs.
What the Company Must Tell You
A compliant breach notification to Arizona residents must include:
- ✓A description of the breach — what happened and when
- ✓The types of personal information that were involved
- ✓What the company is doing to investigate and contain the breach
- ✓Steps you can take to protect yourself (e.g., credit freeze, fraud alert)
- ✓Contact information so you can ask questions
