Phone Number Data Brokers: Who Sells Your Information

What Are Data Brokers

Data brokers are companies that collect, aggregate, and sell personal information — including phone numbers, addresses, email addresses, demographic data, and behavioral profiles — without most people's knowledge or meaningful consent. The industry includes publicly traded companies like Acxiom (now LiveRamp), Oracle Data Cloud, Experian, and hundreds of smaller operators.

These companies build profiles by combining data from public records (voter registrations, property deeds, court filings), commercial sources (purchase histories, loyalty programs, app data), and digital tracking (website cookies, social media activity, location data from mobile apps).

A single consumer profile can contain over 1,500 data points. Your phone number is typically linked to your full name, current and previous addresses, email addresses, estimated income, purchasing habits, political affiliation, health interests, and family connections.

Major Data Brokers With Your Number

The largest data brokers holding phone number data include: Acxiom/LiveRamp (profiles on 2.5 billion consumers globally), Oracle Data Cloud (5 billion consumer IDs), Experian (one of the three major credit bureaus, holds data on 220 million Americans), Epsilon (marketing data on 250 million Americans), and LexisNexis (45 billion public records).

People-search sites are a subcategory of data brokers that package this information for individual lookups: Whitepages, Spokeo, BeenVerified, TruePeopleSearch, FastPeopleSearch, and PeopleFinders all maintain databases linking phone numbers to personal information.

There are also telecommunications data aggregators like Neustar (now TransUnion) and Targus Information Corporation that specifically compile phone ownership data from carrier records and sell it to businesses for caller ID services, fraud prevention, and marketing.

How They Collect Your Phone Data

Data brokers collect your phone number through at least a dozen channels: public records (property deeds, voter registrations, court filings, business registrations), commercial transactions (loyalty programs, warranty registrations, magazine subscriptions), app permissions (apps that request contact access upload your entire address book), and web forms (any online form asking for your phone number).

Many mobile apps contain SDKs (software development kits) from data brokers that silently collect data. A 2025 study by the Privacy Research Center found that 72% of free apps in the Google Play Store shared user phone numbers with at least one data broker.

Social media platforms are also a major source. Even if your phone number isn't visible on your profile, Facebook, Instagram, and TikTok use phone numbers for account verification and ad targeting. This data can be accessed by advertisers and, through data partnerships, by brokers.

How to Remove Your Number from Brokers

Removing your number requires submitting opt-out requests to each data broker individually. Start with the biggest people-search sites: Spokeo (spokeo.com/optout), Whitepages (whitepages.com/suppression-requests), BeenVerified (beenverified.com/app/optout/search), TruePeopleSearch (truepeoplesearch.com — click "Remove This Listing"), and FastPeopleSearch (fastpeoplesearch.com/removal).

For major data brokers: Acxiom offers an opt-out at isapps.acxiom.com/optout, Oracle at datacloudoptout.oracle.com, and Epsilon accepts opt-out requests by email (optout@epsilon.com) or mail. LexisNexis requires a written request with identity verification.

The process is tedious — there are over 400 known data brokers operating in the US. Services like DeleteMe ($129/year) and Kanary ($89/year) automate the opt-out process, submitting removal requests on your behalf and monitoring for re-listings. Given that brokers often re-add your data from other sources, ongoing monitoring is more effective than one-time removal.

Prevention: Keeping Your Number Private

Use a secondary phone number for all non-essential purposes. Google Voice (free) gives you a number you can use for online forms, business contacts, and sign-ups. Services like Burner ($4.99/month) provide disposable numbers you can rotate.

Audit your app permissions regularly. On iPhone: Settings > Privacy > Contacts — revoke access for any app that doesn't need your contacts. On Android: Settings > Apps > Permissions Manager > Contacts. Remove apps that have no legitimate reason to access your contact list.

Be cautious with online forms: don't provide your real phone number unless absolutely necessary. When a site requires a phone number for verification, use your Google Voice number. Review privacy policies before sharing your number — look for language about "sharing with partners" or "marketing purposes," which typically means your data will be sold.
