Minn. Stat. 325E.61
Section MN.1
What the statute requires
Under Minn. Stat. 325E.61, a business that owns or licenses computerized personal information of Minnesota residents must notify affected individuals in the most expedient time possible and without unreasonable delay.
Attorney general notification: no general ag requirement (reporting agencies at 500+ residents within 48 hours).
Section MN.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 Minnesota residents: without unreasonable delay
- [2] Attorney general / state agency: no general ag requirement (reporting agencies at 500+ residents within 48 hours)
- [3] Consumer reporting agencies where the breach is large-scale
Section MN.3
Penalties and enforcement
Up to $25,000 per violation; contractual waivers of notification are void.
Private right of action: No. Only the Minnesota Attorney General may enforce.

Section MN.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 Minnesota sits.
Minnesota 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.
