Californians face heavy volumes of SSA/IRS arrest threats, Car Warranty robocalls, and Amazon/Tech Support fraud. In 2024, California residents reported 238,705 fraud cases resulting in total losses of $1,678,703,608, with a median loss of $542 per victim. To help authorities track these criminals, you should report any fraudulent calls to:
Yes. California law does not prohibit residents from using reverse phone lookup services for personal use - but California has by far the most comprehensive privacy framework in the US, giving residents tools that simply don't exist in most other states. The Fair Credit Reporting Act (FCRA) prohibits using lookup results for employment screening, tenant decisions, or credit and insurance underwriting in every state. California's state law supplements these federal rules; it does not replace them.
California operates under the California Consumer Privacy Act / California Privacy Rights Act (CCPA/CPRA), in effect since January 1, 2020, with major CPRA amendments from January 1, 2023. What sets California apart is the 2023 Delete Act (SB 362), which directed the California Privacy Protection Agency (CPPA) to build a centralized Delete Request and Opt-Out Platform (DROP). The DROP became available to consumers on January 1, 2026, and data brokers are required to begin processing DROP deletion requests starting August 1, 2026 (Cal. Civ. Code §§ 7610–7616). That means Californians can submit a single request to remove their phone number and personal data from every registered data broker at once - a capability no other state currently offers.
Beyond the DROP, CCPA/CPRA gives California residents the right to opt out of the sale or sharing of personal information (§ 1798.120), access and correct data held about them, request deletion, and receive a portable copy. The 45-day response window applies. Unlike most state laws, CCPA/CPRA covers employees and B2B contacts in addition to consumers, and there is no blanket small-business exemption. Enforcement sits with the dedicated CPPA, not just the Attorney General.
Under CCPA/CPRA, you can request removal of your phone number and personal details from reverse lookup services. Visit each site and click "Do Not Sell or Share My Personal Information" to submit a deletion request.
A reverse phone lookup can provide a business name, but that alone does not confirm legitimacy. While California has over 1,023,181 business establishments based on Census data, you should verify the company by searching for it in the California Business Search.
California has 7.5 million VoIP subscriptions, more than the total phone subscriptions in most states. Tech adoption and remote work explain part of this, though mobile numbers still dominate at 48.7 million. Traditional landlines represent only 1.6 million.
