Nevada Data Breach Notification Law

The Nevada data breach notification law in NRS 603A

NRS 603A.220 starts the clock when a business discovers a breach or hears about it from someone else, and from then on the standard is the most expedient time possible and without unreasonable delay ¹. Police requests and the work of scoping and repairing the system can stretch that. No state office receives a filing.

The chapter was amended in 2025, but those changes touched other sections, not the notice rule.

No harm test in Nevada

Deciding the thief probably will not use the data does not get a Nevada business out of sending letters. A breach is an unauthorized acquisition that materially compromises the security, confidentiality or integrity of personal information, and that is enough ¹.

Past the standard identifiers, three items catch many small offices:

• Login credentials for an online account, which count on their own
• Medical ID numbers
• Health insurance information

Encrypted records are outside the definition; the code is silent on a theft that includes the key ¹.

That health coverage puts Las Vegas clinics, dental offices and pharmacies under two regimes at once. The federal one allows no more than 60 calendar days from discovery, and no unreasonable delay before that ²; the state one asks for the most expedient time possible. The federal half is explained in our walkthrough of the HIPAA notice rule.

Security rules that come with the notice law

Chapter 603A asks more than notice. It requires reasonable security, compliance with PCI DSS for businesses that accept payment cards, and encryption of personal information sent outside the business's secure system ¹. For a restaurant, shop or clinic taking cards, that is a state law duty as well as a card network rule. The controls behind each duty are laid out in security basics for a small company.

Businesses that comply with the Gramm-Leach-Bliley Act are treated as compliant, and installment lenders licensed under NRS 675 have been excluded since 2023. When a hosting company or other vendor loses records it keeps for a client, it owes that client notice immediately ¹.

Injunctions, district attorneys and lawsuits

The Attorney General or a district attorney may sue for an injunction, and a violation of the chapter is a deceptive trade practice under NRS 598.0903 to 598.0999 ³. No court has settled whether a resident may sue over a missing letter. For a sense of scale, Nevadans lodged 13,366 complaints with IC3, the FBI's online complaint center, in 2025, tallying about $302 million in losses ⁴.

If your Nevada business is breached

With the attack still live, an insured business rings the carrier's incident line before anyone else, files at ic3.gov so the FBI has a record, and copies evidence before any machine is restored or reimaged ⁵⁶⁷.

Next, an outside containment and forensics team (or your own IT support for a small event) locks the intruder out, and someone builds the list of who was affected and where they live. Customers from California bring its 30-day deadline with them; Arizona allows 45 days. Every other state sits in the complete state-by-state breach table.

Chapter 603A was reread against this page on October 13, 2026. A plain-language summary is no replacement for legal advice, so a Nevada attorney should confirm how NRS 603A.220 applies to you.
