Yes. Connecticut does not restrict the personal use of reverse phone lookup services, and residents benefit from one of the more actively enforced state privacy laws in the country. The Fair Credit Reporting Act (FCRA) prohibits using lookup results for employment, tenant, or credit decisions nationwide. Connecticut's CTDPA builds on these federal protections.
The Connecticut Data Privacy Act (CTDPA, Pub. Act 22-15, as amended by Pub. Act 23-16) has been in effect since July 1, 2023 and was strengthened again in 2025. Connecticut residents can opt out of the sale of their personal data and targeted advertising, and have rights to access, correct, delete, and port their information - all with a 45-day response window. Nonprofits are generally exempt.
What distinguishes Connecticut is active enforcement: the state Attorney General published a public compliance enforcement report in early 2024, one of the first state AGs to do so. Businesses operating in Connecticut know enforcement is real, which in practice tends to improve compliance with opt-out requests.
