Is Reverse Phone Lookup Legal in Delaware?
Yes. Delaware does not restrict the personal use of reverse phone lookup services. The state's 2025-effective privacy law gives residents meaningful rights to control their data held by lookup services. The Fair Credit Reporting Act (FCRA) prohibits using lookup results for employment, tenant, credit, or insurance decisions everywhere in the US. Delaware's state law layers additional rights on top.
Your Privacy Rights as a Delaware Resident
The Delaware Personal Data Privacy Act (DPDPA, Del. Code tit. 6, §§ 12D-101 et seq.) took effect January 1, 2025. Delaware's law stands out for its broad nonprofit coverage - unlike most state privacy laws that grant blanket nonprofit exemptions, the DPDPA covers nonprofits with only narrow carve-outs, similar in scope to California and Maryland. This matters for lookup services that may operate as or through nonprofit structures.
Delaware residents have 45 days to receive responses to access, correction, deletion, and portability requests. There is no small-business exemption, and the right to correct inaccurate data is included.
