How do spammers get my phone number? 5 ways, and what we found on ours

How do spammers get my phone number? Mostly, someone sold it. People-search sites and data brokers list your number next to your name and address, and anyone can buy the list. On our own account, Cloaked has reported 1,363 phone-number exposures secured since June 2025, and it found our info in 14 data breaches.

The short version: how spammers get your phone number, on our real account.

How do spammers get my phone number? The 5 main ways

1. People-search sites and data brokers

This is the big one. The FTC explains that people-search sites are a type of data broker that collects information from public records, social media and other brokers, then sells reports (FTC). Starting from just a name or a phone number, a report can show your age, past addresses, relatives and more. A spammer doesn't need to hack anything. They buy it.

2. Data breaches

When a store, app or service gets breached, phone numbers usually leak with emails and passwords. Those lists get traded. On October 18, 2026, Cloaked found our info in 14 data breaches.

3. Forms you filled out

Loyalty cards, warranty cards, contests, coupon sign-ups and "enter your number for 10% off" pop-ups. Some companies share or sell what they collect, which is how a number you gave once ends up on lists you never agreed to.

4. Auto-dialers that just try numbers

Some robocallers don't need your name at all. Their software dials number after number and keeps the ones that answer. That's why a brand-new number can get spam on day one.

5. You answered or replied once

Picking up, pressing a key or texting back STOP to a scammer tells them the number is live, which makes it worth more on the next list. We covered this in our toll text scam guide: don't reply to unknown texts at all.

What we found when we checked our own number

Cloaked splits what it has secured on our account by type. Out of 14,636 exposures since June 24, 2025, 1,363 were phone numbers. ("Exposure" is Cloaked's term; it isn't one site each.)

The sites were mostly people-search and records sites: Radaris (13 exposures), VeriPages (8), AffordableBackgroundChecks (12), and a long run of state records and arrest sites. One wasn't automatic. PeopleConnect needed a manual step from us, which clears 13 sites at once.

How to get your phone number off these lists

  1. Search yourself. Search your name and city, and your phone number, on Google and on the big people-search sites. Write down every site that shows your number.
  2. Opt out, one site at a time. Most sites have an opt-out page. It's free, but some ask you to verify your identity, and the FTC notes your info can reappear when public records change, so check back every few months.
  3. In California, use DROP. The state's free Delete Request and Opt-out Platform sends one deletion request to every registered data broker, over 600 of them. Brokers had to start processing requests on August 1, 2026 and have 90 days to delete your records (Malwarebytes).
  4. Stop handing it out. Skip the phone field when it's optional, and never post your number publicly.
  5. Filter what still gets through. Turn on your phone's spam filter: iPhone steps and Android steps.

Doing the opt-outs yourself works, it just takes time. We pay for Cloaked to do it and keep checking. Here's what it did on our account, including what it couldn't finish without us.

Common questions about how spammers get your number

How do spammers get my phone number?

Mostly from data brokers and people-search sites that sell your number with your name and address, and from data breaches. Some calls are also auto-dialed number by number, which is why even a brand-new number can get spam.

Can I find out who sold my phone number?

Usually not for a specific call. You can search your own name on people-search sites to see which ones list your number, then opt out of each one. Your state's data broker registry, where one exists, lists the brokers operating there.

Does removing my number from data broker sites stop spam?

It reduces how many lists your number is on, but it won't stop every call or text, and your number can come back when public records change. The FTC suggests checking the sites again periodically. Pair opt-outs with your phone's spam filter.

Will a new phone number stop spam calls?

For a while, maybe. But numbers get recycled and auto-dialers call ranges of numbers, so a new number can still get spam. Keep the new one off sign-up forms and public profiles to make it last.
