Montana’s governor signed their own privacy law into effect on May 19. This new consumer data privacy act will go into effect on October 1, 2024. This makes Montana the ninth state in the US to enact their own privacy law.
The Montana Consumer Data Privacy Act (MCDPA) shares a lot of similarities to the Connecticut and Virginia laws. There have been a lot of the recent US Privacy laws that have been following similar format. It suggests these two laws are becoming a bit of a template for other states wishing to implement their own law.
Who it Affects
The MCDPA applies to companies that do business in Montana or target products or services to Montana consumers and:
- Control or process personal data of 50,000 or more Montana consumers (excluding personal data controlled or processed solely for the purpose of completing a payment transaction); or
- Control or process personal data of 25,000 or more Montana consumers and derive over 25% of gross revenue from the sale of that data.
Consumer Rights
- Right to opt-out

- Right to correction
