Search Phone Number on Facebook: What Still Works in 2026

You can't search a phone number on Facebook the way you used to, because Facebook switched that feature off in April 2018. Typing a number into the search bar now mostly returns nothing. A few side doors still work, and a phone lookup that scans social networks is the fastest way to find out if a number has a Facebook profile at all.

• Search bar: phone number search was disabled on April 4, 2018
• Still possible: contact upload, Messenger, and searching the number as text
• Catch: each one depends on the owner's privacy settings or your own address book
• Faster route: a lookup that covers social networks, free preview in about 60 seconds
• Private: the person is never notified

How do you search a phone number on Facebook?

You try one of four side doors, because the search bar no longer takes phone numbers. The graphic below shows the order most people try them in, and each one has a catch.

Each route trades speed for privacy limits. A lookup that scans social networks skips the guesswork.

Can you still search Facebook by phone number?

Not in the search bar. On April 4, 2018, Facebook said it had disabled the feature that let people enter a phone number or email address into search. Its reason was abuse: bad actors used it to scrape public profile information, and Facebook said most people on the platform could have been scraped that way.

The door was closed on purpose, so you won't find a hidden setting that reopens it. That is why so many guides online send you in circles. The rest of this post covers what still works and where each method gets stuck.

How do you find someone on Facebook by phone number?

The main route left is contact upload. If you save the number in your phone and let Facebook sync your contacts, the person can show up in People You May Know.

1. Save the number in your phone contacts.
2. Open Facebook and choose to upload or sync contacts.
3. Check People You May Know for a match.

The friction is real. You hand Facebook your whole address book to look up one person. The match only appears if the owner also gave Facebook that number. And suggestions can take time or never show. If you only want one answer, this is a slow and leaky way to get it.

How do you find someone on Messenger by phone number?

Open Messenger, search the number, or use the option to add someone by phone number. It works only if the owner linked that number to their account and allows people to find them with it. If they turned that off, you get nothing and you won't be told why.

Treat a miss as unclear, not as proof they have no account.

How do you find someone's phone number on Facebook?

Search the number as plain text, in quotes, in posts, groups and Marketplace listings. People often type their number into a for-sale listing or a group post, so a match can lead you to the profile that posted it.

If you want the reverse, finding a number that belongs to a profile, look at the About section and any Marketplace listing. Most people hide their number, so it usually isn't there. This is also the answer to "how to find a phone number on Facebook": it only works when the owner chose to show it.

Only the last row does not depend on the owner's settings or your own address book.

How do you find a Facebook account by phone number with a lookup?

Enter the number into a lookup that scans social networks and public records. Deepscanner returns a free preview in about 60 seconds with the carrier, line type and location. The full report, about 2 minutes, can list social profiles linked to the number, plus the owner's name and photos.

This works because it doesn't rely on Facebook's search at all. It checks whether the number shows up on social networks and the wider web, which is the question you were really asking. Results depend on what is public, and the same number can surface accounts on Instagram, X or LinkedIn that Facebook never shows you.

How do you hide your phone number on Facebook?

Open your Facebook privacy settings and change who can look you up using the phone number you provided, then set your number to Only Me in profile contact info. This stops people finding you by the same routes in this post. Menu names change, so look under Settings and privacy, then Privacy.
