Data removal. Updated 2026-09-13. About 4 minutes to read.
Opt out of reverse lookup sites while you still control the number, unlist from caller ID apps, then add a port-out lock with your carrier.
Your mobile number is probably listed on reverse phone lookup sites, in caller ID apps and in at least one breach dataset. That is how strangers match it to your name and address, and how scammers find it.
You can remove most of those listings for free in an evening. You cannot recall copies already sold or leaked, so this guide also covers the step people skip: locking the number with your carrier so nobody can take it over. Expect to re-check the listings every 90 days.
Find every place your number shows up
Search your number on Google and Bing in three formats: with spaces, with dashes and with the country code.
Run the free phone exposure check on this site to see which kinds of sites and datasets tend to hold it.
Search the number on Have I Been Pwned in international format, such as 1 for the US or 61 for Australia followed by the number without its leading zero.
Look yourself up on Whitepages, USPhoneBook, Spy Dialer and Spokeo using the reverse phone search.
Install nothing. Search Truecaller's website for your number rather than downloading the app, which asks for your contacts.
Opt out of reverse phone lookup sites
Whitepages: whitepages.com/suppression-requests. It verifies by calling the number on the listing, so do this before you change numbers.
USPhoneBook: built around reverse lookup, so it ties a mobile to a home address. Use the opt-out link in its footer and confirm by email.
Spy Dialer: spydialer.com/optout.aspx. It can play a number's voicemail greeting, which may say your name.
Spokeo, TruePeopleSearch and Nuwber: each shows phone numbers on the main profile, so remove the whole listing.
Unlist from caller ID apps
Caller ID apps know your name because other people uploaded their address books. You never signed up, so there is no account to delete. You have to ask for the number to be unlisted.
Truecaller: truecaller.com/unlisting. If you ever installed the app, deactivate your account first, or the number goes straight back in.
Sync.me: sync.me/unsubscribe removes your entry without an account.
Hiya: there is no public web form. Email its data protection contact with proof you own the number.
Caller ID apps rebuild entries from new contact uploads, so an unlisted number can reappear. Check again in 90 days.
Remove your number from Google search results
Open myactivity.google.com/results-about-you, or in the Google app tap your profile picture and choose Results about you.
Add every phone number you want monitored.
Review the pages Google finds and request removal for each one that shows your number next to your name.
Keep the broker opt-out as well, because delisting hides the page from Google but does not delete it.
Stop apps from exposing the number
Facebook: in Settings and privacy, open How people find and contact you, set who can look you up by phone number to the narrowest option, and hide the number on your profile.
Signal: Settings > Privacy > Phone Number. Set who can see your number and who can find you by number to Nobody, and share a username instead.
WhatsApp: set your profile photo and About to My contacts, so a stranger who has your number sees less.
LinkedIn and payment apps: remove the number from public contact info and turn off find-me-by-phone options.
Lock the number itself against SIM swaps
A public number is a target. In a SIM swap, a criminal convinces your carrier to move your number to their SIM, then receives your text message codes. Carriers now offer free locks. In the US, FCC rules require wireless carriers to authenticate customers before a SIM change or port-out.
AT&T: turn on Wireless Account Lock in the myAT&T app.
Verizon: turn on Number Lock and SIM Protection in My Verizon.
T-Mobile: turn on Port Out Protection and SIM protection in your account settings.
Australia: carriers must verify your identity with an extra step, usually a code sent to your phone, before a number can be ported.
UK: moving a number needs a PAC code sent by text, so an unexpected PAC or switching message is a warning sign. Call your network straight away.
Change the number or add a second one?
Changing your number is disruptive, because banks, two-factor logins and friends all use it. It makes sense if the number is flooded with scam calls or tied to a harassment case. Breach datasets and scraped lists do not update, so a new number starts clean.
For most people, a second number is the better fix. Use a cheap prepaid SIM, or Google Voice in the US, for shops, loyalty programs, delivery apps and quote forms. Keep your real number for banking, family and two-factor authentication.
Frequently asked questions
Why does my phone number show my name and address online?
Reverse lookup sites match phone numbers against directory listings, marketing data, public records and contact lists uploaded to caller ID apps. Once one source pairs your number with your address, the sites copy it.
Can I remove my number from Truecaller?
Yes. Deactivate any Truecaller account you have, then request unlisting at truecaller.com/unlisting. Because entries come from other people's contacts, check again after a few months.
How did my phone number get into a data breach?
Any company that stored it can lose it, and scraping can collect it too. The 2021 Facebook dataset exposed phone numbers for more than 500 million accounts, most of which had no email address in the data.
Should I just get a new phone number?
Only if the current number is flooded with scam calls or tied to a safety problem. Otherwise remove the listings, lock the number with your carrier and use a second number for sign-ups.
Will removing my number stop spam calls?
It reduces calls that come from marketing and people-search lists. Scam callers also dial numbers at random and buy breach data, so keep your phone's spam filter and your carrier's blocking turned on too.
