Whose Number Is This?
Enter any US or Canada number and see who it's listed to, where it's registered, and what kind of line it is.
To find out whose number a phone number is, run it through a reverse phone lookup. 1Lookup's free tool returns the listed owner where one exists in public records, plus the registration city and state and the line type. Unlisted numbers are common: most mobiles have never appeared in a public directory.
Results come from public directory records and carrier data and are provided for informational purposes only. Coverage is incomplete, particularly for mobile numbers, and records can be out of date. This service is not a consumer report and must not be used to make decisions about credit, insurance, employment, tenancy, or any other purpose covered by the Fair Credit Reporting Act. Do not use it to harass, stalk or intimidate anyone.

Find Out Whose Phone Number This Is
A number turns up in your call log, on a form, in a listing, or written down with no note about who it belongs to. Enter it here and the lookup searches public directory records for a registered owner and queries carrier data for where the line is registered and what type it is.
What you get back depends on the number. Landlines and business lines are well represented in public records and usually resolve to a name. Mobile numbers frequently do not, because there is no public mobile directory in the US and listing is the exception rather than the rule. A no-match result on a mobile is the normal outcome, not a sign that anything is wrong with the number.
The line type is worth reading whatever else comes back. Mobile and landline numbers are tied to a carrier and a real registration area. VoIP numbers are cheap, instant and disposable, which makes them the standard choice for spam operations, and also for perfectly ordinary business phone systems. Combined with the location and whether the number is listed at all, it usually tells you what you need to know.
How the Number Lookup Works
Enter the phone number
Any 10-digit US or Canada number, in whatever format you have it. The tool normalises brackets, dashes, dots and a leading 1 automatically.
We search records and carrier data
The lookup checks public directory listings for an owner and queries live carrier data for the line type and registration location. Nothing is served from a stale cached list.
Read the result
You see the listed owner where one exists, the city and state, and the line type. Sign up free to unlock the full name, address and associated records.
Owner lookup from public records
Where the number appears in public directory data, you get the name it is listed under and the area it is registered in.
Live carrier and line type
Mobile, landline or VoIP, resolved against carrier data at the moment you search rather than from a snapshot taken months ago.
Registration location
The city and state the number is registered in, which is often the quickest way to place a number you half-recognise.

Who uses this tool
A number with no name attached
In your call history, on a note, or in a contact form submission. Identify it before you decide whether to call back or reply.
Verifying a number someone gave you
Check that a number on a listing, invoice or business card resolves to the location and line type you would expect for that business.
Checking a number before you deal with someone
A seller or contractor reachable only on a disposable VoIP line is worth a second thought before money changes hands.
Cleaning up your own records
Working out which of several numbers for one contact is the live mobile, before a call, a text or a send.
Frequently asked questions
Can I find out whose number this is for free?
Yes, within limits. Five lookups a day on this tool and fifteen a day across all our free tools, no account needed. The free result shows a masked owner name, the city, state and line type. A free account unlocks the full record and 1,000 lookups over a seven-day trial.
Why is there no name for this number?
Most likely it is a mobile. There is no public mobile phone directory in the US, so unlisted is the default state for mobile numbers. It usually means nothing about the number or its owner.
Is this the same as a reverse phone lookup?
Yes, it is the same search framed as the question people actually type. If you want the version aimed at looking up a number you already know something about, our reverse phone lookup runs the same check.
Can I look up a number that texted me?
Yes, the same lookup works for numbers that sent you a text. If you want the message itself assessed, paste it into our free scam text message checker.
Is looking up a phone number legal?
Searching public directory and carrier data is legal in the US. What matters is what you do with it. This service is not a consumer report and cannot be used for credit, insurance, employment or tenancy decisions, and it must never be used to harass or stalk anyone.
Can you look up international numbers?
This tool covers US and Canada. For numbers elsewhere, our free HLR lookup tells you whether a mobile is active and identifies the country and carrier.
