Statute

Miss. Code Ann. 75-24-29
Section MS.1
What the statute requires
Under Miss. Code Ann. 75-24-29, a business that owns or licenses computerized personal information of Mississippi residents must notify affected individuals without unreasonable delay.
Attorney general notification: no ag notification requirement at any threshold.
Section MS.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 Mississippi residents: without unreasonable delay
- [2] Attorney general / state agency: no ag notification requirement at any threshold
- [3] Consumer reporting agencies where the breach is large-scale
Section MS.3
Penalties and enforcement
Unfair trade practice; up to $10,000 per willful violation under the Consumer Protection Act.
Private right of action: No. Statute expressly creates no private right of action.

Section MS.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 Mississippi sits.
Mississippi 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.
