Data Breach Notice to Residents and State Authorities in Arkansas

Short answer Arkansas requires notice to affected residents in the most expedient time and manner possible without unreasonable delay after a qualifying breach, unless a reasonable investigation finds no reasonable likelihood of harm. Its Attorney General clause applies when more than 1,000 individuals are affected and expressly points to the nonowner-holder paragraph; it calls for notice by the earlier of affected-person notice or 45 days after the harm determination. A nonowner holder must notify the owner or licensee immediately after discovery.

Requirements one by one

Breach and risk decision

Ark. Code § 4-110-103(1) defines a breach as unauthorized acquisition of computerized personal information that compromises security, confidentiality, or integrity. The definition excludes good-faith employee or agent acquisition for the holder's legitimate purposes if the information is not otherwise used or disclosed without authorization. Section 4-110-103(7) covers a name with a Social Security number, Arkansas license or identification number, financial account access data, or medical information; § 4-110-103(7)(E) added biometric data in 2019.

Under § 4-110-105(d), notice is unnecessary if a reasonable investigation finds no reasonable likelihood of harm to customers.

Residents, owners, and the Attorney General

Ark. Code § 4-110-105(a) requires notice to Arkansas residents whose unencrypted personal information was or reasonably is believed acquired by an unauthorized person. It must be made in the most expedient time and manner possible without unreasonable delay after discovery or notification, allowing necessary scope and system-restoration work. There is no fixed outer day count for residents. Under § 4-110-105(b)(1), a nonowner maintainer tells the owner or licensee immediately after discovery.

The Attorney General clause in § 4-110-105(b)(2) applies when more than 1,000 individuals are affected. Its text identifies the person or business required to make a disclosure under subsection (b)(1), the nonowner-holder paragraph. It calls for AG disclosure at the same time as disclosure to an affected individual or within 45 days after determining a reasonable likelihood of customer harm, whichever is first. Section 4-110-105 has no separate nationwide consumer-reporting-agency notice.

Delivery and substitute notice

Section 4-110-105(e) allows written or qualifying email notice. Substitute notice is allowed if direct delivery would cost over $250,000, the affected class exceeds 500,000, or contacts are insufficient. It requires email where addresses exist, a conspicuous website post if the holder has a site, and statewide media. The section does not enumerate resident-letter contents.

What trips people up

A police determination pauses notice. Under § 4-110-105(c), notice may be delayed when law enforcement finds it would impede a criminal investigation, then must be made after the agency says it will not compromise the investigation.

The documentation rule has its own clock. Section 4-110-105(g), added in 2019, requires a written breach determination and supporting documentation kept for five years. A written AG request starts a 30-day production deadline; the material is confidential.

Alternative compliance has a condition. Section 4-110-105(f) recognizes a holder's own notification policy if its timing is consistent with the Act and it follows that policy. Section 4-110-106 recognizes a state or federal law only if it provides greater personal-information protection and at least as thorough breach disclosure.

Common questions

Does the more-than-1,000 count refer only to Arkansas residents?

No. The words in § 4-110-105(b)(2) are “more than one thousand (1,000) individuals”; the paragraph does not limit that count to state residents.

Is a 45-day resident deadline stated?

No. Section 4-110-105(a)(2) sets a without-unreasonable-delay resident clock. The 45-day period appears in the Attorney General paragraph, subsection (b)(2).
