This page summarises the deadline to notify affected residents, the attorney general notification threshold, whether a private right of action exists, and the penalties for late or missing notification. Every provision is cited to its source statute and was verified in June 2026.

Ark. Code Ann. 4-110-101 et seq.
Section AR.1
What the statute requires
Under Ark. Code Ann. 4-110-101 et seq., the Personal Information Protection Act, a business that owns or licenses computerized personal information of Arkansas residents must notify affected individuals in the most expedient time and manner possible and without unreasonable delay.
Attorney general or state-agency notification is more than 1,000 arkansas residents. Where required, the timeline is: at the time of individual notice or within 45 days of a harm determination, whichever is first.
Section AR.2
What triggers notification
Like most US state statutes, notification is triggered by the unauthorized acquisition of unencrypted, unredacted computerized personal information that compromises its security, confidentiality, or integrity. Two concepts recur across the states and apply here.
Encryption safe harbor
Personal information that was encrypted, and where the encryption key was not also acquired, generally does not trigger notification. A stolen device with full-disk encryption is typically a non-event; an unencrypted record, or an encrypted record where the key was exposed alongside it, is a reportable breach.
Who must be notified
- [1] Affected Arkansas residents: without unreasonable delay
- [2] Attorney general / state agency: more than 1,000 arkansas residents
- [3] Consumer reporting agencies where the breach is large-scale
Section AR.3
Penalties and enforcement
Up to $10,000 per violation under the Deceptive Trade Practices Act; willful violations are a misdemeanor.
Private right of action: No. No express private right of action under PIPA.

Section AR.4
How this compares to the strictest states
The strictest US deadlines are 30 days (California, Florida, Washington, Colorado, Maine, New York, New Jersey). The majority of states use a qualitative "without unreasonable delay" standard with no fixed day cap. Here is where Arkansas sits.
Arkansas does not set a numeric deadline. It uses a "without unreasonable delay" standard, which regulators interpret as days to weeks, not months. Organizations operating across multiple states should default to the strictest applicable clock, which can be as short as 30 days in states such as California, Colorado, Florida.
