How to search for a Facebook account by phone number
Facebook's search function lets you look up accounts using a phone number, but the results depend on whether that person made their number searchable. Open Facebook, click the search bar at the top, type the phone number in full (including the country code if it's international), and press Enter. If the account owner set their privacy settings to allow phone number searches, their profile will appear in the results.
If nothing shows up, it means either the account doesn't exist, the number isn't linked to a Facebook account, or the person turned off phone number search in their privacy settings. This is a common privacy choice — many people disable it specifically to avoid being found this way.
The phone number needs to be the one actually registered to the account. If someone uses a different number for Facebook than the one you have, this method won't work. You might have an old number, a work number they no longer use, or simply the wrong contact information.
Key Takeaways
- Facebook's search bar accepts phone numbers, but only returns results if the account owner allowed phone number searches in their privacy settings.
- The phone number must be the exact one registered to the account — if it's outdated or incorrect, the search will return no results.
- If a search fails, try searching by name instead, especially if you know their location, workplace, or school.
- Some people intentionally disable phone number search to keep their account private, so a failed search doesn't mean the account doesn't exist.
Why some phone number searches don't work
Facebook gives every user control over who can find them by phone number. To disable this, someone goes to Settings and Privacy, then Settings, then Privacy, and unchecks "Who can look you up using the phone number you provided?" If they've turned this off, you won't find them even if you have the correct number.
This setting exists because phone numbers are harder to change than usernames and are often more personal. Someone might be comfortable with friends finding them by name but not want strangers or old contacts reaching them through their number.
Another reason a search might fail: the number might not be verified. If someone added a phone number to their account but never confirmed it through a text message or call, Facebook won't index it for search purposes.
Searching by name when the phone number doesn't work
If the phone number search returns nothing, switch to searching by name. Type their full name into the search bar and look through the results. If you know where they live, work, or went to school, you can narrow the results by clicking on a profile and checking their "About" section — it often lists this information.
Facebook also shows mutual friends on profiles. If you see someone you both know, that's a strong signal you've found the right person. Be cautious about profiles with no mutual friends, no profile picture, or very little public information — these might be inactive accounts or accounts belonging to someone else with the same name.
Using reverse phone lookup services
Several websites claim to match phone numbers to social media accounts, including Facebook. Services like TrueCaller, WhitePages, and Spokeo maintain databases of phone numbers linked to public profiles. These services vary in accuracy and may charge a fee for detailed results.
Keep in mind that these services pull from publicly available information, so they only work if the person's phone number is already public somewhere online — perhaps listed on a business website, directory, or their own social media profiles. If someone keeps their number private, these services won't have it.
The information these services hold can also be outdated. A phone number might be linked to an old address or a person who previously owned that number, so always verify the results by checking the actual Facebook profile.
What to do if you can't find the account
If searching by phone number and name both fail, the account might not exist, might be deactivated, or might be set to very high privacy settings. Facebook allows users to deactivate their accounts temporarily or delete them permanently — in either case, the profile becomes invisible to search.
You could also try searching on other platforms. The person might use Instagram (which is owned by Meta, Facebook's parent company) or LinkedIn instead. If you have their email address, you can search by that on some platforms, or you might find them through a mutual friend's follower list.
If you're trying to reconnect with someone, consider reaching out through a mutual friend instead. They might have more current contact information or be able to pass along a message.
Privacy and safety considerations
Searching for someone's account is generally harmless, but be thoughtful about why you're doing it and what you do next. If someone has made their account hard to find, they may have done so intentionally. Respect that choice.
Never use phone number searches to find accounts for harassment, impersonation, or any deceptive purpose. Facebook's terms of service prohibit using the platform to harm others, and doing so can result in your account being suspended or banned.
If you're searching for someone who may not want contact with you — an ex-partner, a former employer, someone you had conflict with — consider whether reaching out is appropriate. A failed search might be a signal to let the connection go.
Frequently Asked Questions
Can I search for someone on Facebook if I only have their phone number?
Yes, if they linked that number to their account and didn't disable phone number search in their privacy settings. Type the full number including country code into Facebook's search bar. If nothing appears, either the number isn't linked to an account, the account owner turned off phone search, or you have the wrong number.
What's the difference between searching by phone number and searching by name?
Phone number search only works if the person allowed it and the number is registered to their account. Name search shows all profiles matching that name, so you have to look through results to find the right person. Name search is more likely to return results but requires more effort to verify you found the right account.
If someone's profile doesn't show up in a phone number search, does that mean they don't have a Facebook account?
Not necessarily. They might have an account but disabled phone number search, or the number you have might be outdated or incorrect. Try searching by name instead, or ask a mutual friend if they know whether the person uses Facebook.
Are reverse phone lookup services reliable for finding Facebook accounts?
They work only if the phone number is already public somewhere online. Results can be outdated or inaccurate, so always verify by checking the actual Facebook profile. Many of these services charge fees, and free versions often show limited information.
Is it legal to search for someone's Facebook account using their phone number?
Yes, searching is legal. You're using Facebook's own search function, which is designed for this purpose. What matters is what you do after you find them — contacting someone who doesn't want contact, impersonation, or harassment are not legal and violate Facebook's terms of service.
