This free reverse phone lookup shows who a US phone number is listed to.
A reverse phone lookup starts with a phone number and finds the person or business it is listed to. 1Lookup's free reverse phone lookup tells you whether a US number is listed, shows part of the name, gives the city and state on the listing, and never calls or texts the number.
- No signup to try
- Name, city and state

A reverse phone lookup finds who a phone number is listed to.
A phone book goes from a name to a number. A reverse phone lookup goes the other way: you start with the number and find who it is listed to. Enter a US number above and the lookup checks it against directory listing records. It tells you whether the number is listed to someone, shows part of the name, and gives the city and state on the listing. Nothing is sent to the number, so its owner never knows you looked.
What comes back depends on the number. Landlines and business lines are well represented in listings and usually return a name. Mobile numbers often do not, because the US has no public directory of mobile numbers, so a no-match on a mobile is the normal outcome rather than a warning sign.
Numbers also change hands. The FCC estimates that about 35 million US phone numbers are disconnected and given to someone new every year, and its rules make a disconnected number wait at least 45 days before it is reassigned. Treat an old listing as a lead to confirm, not proof. The full record, on a 7-day free trial, adds the full name, a second name when the listing has one, the company for a business line, the street address and ZIP code, the email on file when there is one, and a Do Not Call flag.
Each of our free number lookups answers a different question.
If the number just called you and you are deciding whether to call back, start with our free who called me lookup. For a number that turned up in a text, a form or a listing, use our free whose number is this lookup. And if the first three digits are all you need, look up any US area code. To see only the name a number shows on caller ID, use our free CNAM lookup.
A reverse phone lookup takes three steps, and the number is never called.
Enter the phone number
Type or paste any 10-digit US number. Dashes, brackets, spaces, dots and a leading 1 are all cleaned up automatically.
We search the listings
The lookup checks the number against directory listing records for a name and the city and state on the listing.
Read the result
You see whether the number is listed, part of the name, and the city and state. A 7-day free trial shows the full name, street address and email on file.
There are five common ways to find out who a phone number belongs to, and each one shows something different.
What each method can tell you about a US phone number, and where it tends to fall short. Your own phone and the apps only show what the owner or the carrier chose to publish.
| Method | What it costs | What it shows | Where it falls short |
|---|---|---|---|
| Search the number on Google, in quotes | Free | Pages where the number was published, which is mostly businesses | Personal mobiles are rarely on any web page |
| Your phone's caller ID | Free | The name the carrier passes along with the call, when there is one | Often blank or only a city for mobiles, and caller ID can be faked |
| WhatsApp or Telegram | Free | A profile name or photo, if the number has an account | Only what the owner chose to show |
| 1Lookup free reverse lookup | Free, no signup | Whether it is listed, part of the name, and the city and state | Part of the name only, and US numbers only |
| 1Lookup full record | 7-day free trial | Full name, a second name, company, street address and ZIP code, email on file, line type and a Do Not Call flag | Only as current as the listing, and US numbers only |
It shows who a number is listed to.
When the number is in directory listings, you see part of the name plus the city and state on the listing, which is usually enough to tell who it is.
It shows the caller ID name when no person is listed.
Some numbers carry only the name a phone shows on caller ID, often a business name. The free lookup shows that name in full.
Nobody is told that you looked.
The lookup reads listing records only. No call or text goes to the number, so its owner never sees that it was checked.
Whole lists run through the dashboard or the API.
With an account, upload a CSV of numbers in the dashboard or call the 1Lookup API. Each reverse phone lookup uses 10 credits, and the full record comes back for every number with a listing.

Frequently asked questions
Is there a reverse phone lookup that's actually free?
Yes, within limits, and this is one. The lookup above tells you free and without an account whether a US number is listed, part of the name, and the city and state on the listing. The full name, street address and email need the 7-day free trial, and the result says so up front rather than after a progress bar. Fully free, fully unmasked people data is rare, because the records cost money to keep current.
How can I reverse lookup a phone number without paying?
Run it above: the listing status, part of the name, and the city and state cost nothing and need no account. Two other free routes are worth knowing: search the number in quotes on a search engine, which works when the number belongs to a business or was posted publicly, and check WhatsApp or Telegram, where a profile name or photo often appears for numbers registered there.
How do I reverse lookup a phone number on Google for free?
Search the number in quotes in several formats: "(415) 555-2671", "415-555-2671" and "+14155552671". Google only finds numbers that appear on public web pages, so this works well for businesses and badly for personal mobiles. When Google returns nothing, a reverse lookup like the one above still can, because it reads directory listing records rather than the public web.
Can I look up a cell phone number?
Yes. The lookup works for mobiles, landlines and VoIP lines. Mobiles return a name less often than landlines, because the US has no public directory of mobile numbers.
What does it mean when no match is found?
Usually that the number has no public listing, which is normal for mobiles. It can also mean the number is new or was recently given to someone new. A no-match does not mean the number is fake, and our free line type lookup still shows whether it is a mobile, landline or VoIP line.
How current are the results?
A listing is only as current as its last update. The FCC estimates that about 35 million US numbers are disconnected and reassigned every year, so an old listing can name a previous owner. Treat a name as a lead to confirm, especially before you act on it.
How is this different from the who called me and whose number is this lookups?
They read the same listing records. The who called me lookup is set up for a missed call and explains caller ID spoofing, and the whose number is this lookup is set up for a number you found in a text, a form or a listing. Use whichever matches your question.
Does the person know I looked up their number?
No. The lookup reads listing records only. No call or text goes to the number, so its owner never sees that it was checked.
Can a reverse phone lookup tell me if a number is a scam?
Not on its own. It tells you who a number is listed to and what kind of line it is. To check a number for spam signs, use our free spam number checker, and to check a text you received, paste it into our free scam text message checker.
Can I look up many numbers at once?
Yes. The free tool checks one number at a time. With an account you can upload a CSV of numbers in the dashboard or call the 1Lookup API, and each reverse phone lookup uses 10 credits.
Does this work for Canadian or international numbers?
The owner search covers US numbers only. For a Canadian number, our free carrier lookup shows its carrier and line type, and for numbers in other countries our free HLR lookup shows whether a mobile is active and which network it is on.
Is reverse phone lookup legal?
Yes. Looking up who a phone number is listed to for personal or business identification is legal in the US. The results are not a consumer report, so they cannot be used for decisions about credit, insurance, employment or tenancy, which the Fair Credit Reporting Act covers.
The first three digits of a US number tell you where it was assigned.
Every area code has its own page with the places it covers, the local time there, and what to do when a call from it looks spoofed. These are the codes people look up most.
