Is the phone carrier lookup really free?
Yes. The lookup is completely free and needs no sign-up or credit card. We cover the cost of the live carrier check, so there are no hidden per-search fees.
What information can I get from a number?
For any valid number you can see the country it belongs to, the network it is on today, the line type (mobile, landline, VoIP, toll-free and more), whether it has been ported from another network where porting records exist, whether the line is in service and prepaid where that can be checked, the international and national formatting, and whether it is a real mobile or a virtual / VoIP line.
Why does the carrier sometimes show "Unknown carrier"?
We check each number against live carrier and number-portability records, which name the current network for most numbers. When that check cannot name one, or is briefly unavailable, we fall back to the official numbering plan - and many countries do not publish carrier-level ranges there. Rather than guess, we show "Unknown carrier" and still give you the country and line type.
Can it tell if a number is VoIP or a real mobile?
Yes, in most cases. The live check reports the line type the carrier records hold for the number, so a mobile shows as a real mobile and VoIP / virtual lines are flagged as VoIP - even after a number has been ported. If the live check is unavailable we estimate the line type from the official numbering plan instead, and the result says which source answered.
How many lookups can I do?
Visitors get 5 free lookups every 24 hours, and signed-in users get 50. If you need to check or use numbers regularly, you can get your own real, SMS-ready number instead.
Do you store the numbers I look up?
To run the live check, the number you enter is sent to our carrier-data providers and to no one else. We keep a private log of lookups for up to 90 days to stop abuse, reuse recent answers for repeat checks, and never publish your searches.
Can a carrier lookup tell me who owns a phone number?
No. A carrier lookup returns the number's country, carrier or network range, line type and formatting - never the owner's name or address. The data comes from numbering plans and carrier routing records, not a personal directory, which is a deliberate privacy choice. To decide whether to trust a number, the line type and VoIP flag are usually what you actually need.
How can I tell if a phone number can receive SMS before I text it?
Check its line type. Mobile (and 'fixed line or mobile') ranges generally accept SMS, while landlines, toll-free and many VoIP numbers often don't. We read this from carrier records rather than pinging the handset, so treat it as a strong indicator - it's handy for cleaning a contact list before a campaign so your texts don't bounce.
Is it legal to look up a phone number's carrier?
Yes. The country, line type and carrier we show come from non-personal numbering and carrier routing data, not private records. Just use the result responsibly - to vet or format a number, not to harass anyone. The lookup is passive, so no message or notification is ever sent to the number you check.
Does the person know I looked up their number?
No. The lookup is completely passive - we never call, text or otherwise contact the number, and the carrier check reads routing records rather than reaching the phone, so its owner gets no notification of any kind.
Why does my number show as VoIP when it is my real mobile?
Some app-based and MVNO numbers really are registered as VoIP by the network that runs them, so the live check reports them that way. If the result says it was estimated from the numbering plan, the live check was unavailable, and a number first issued in a VoIP range keeps that label there even after it is ported. Either way, treat the flag as a strong signal rather than an absolute verdict.
Can I look up several phone numbers at once?
The free tool is built for quick one-off checks - 5 lookups per visitor every 24 hours. If you need to validate numbers in bulk or wire lookups into your own app, our developer API and account plans are the right fit rather than the free page.
What is the difference between this and a paid HLR lookup?
A paid HLR lookup queries the phone's home mobile network to report whether the handset is switched on and reachable. Our check reads live carrier, porting and line-status records instead: the current network, the line type, whether the number was ported and, where it can be checked, whether the line is in service - all without ever reaching the phone. It does not tell you whether a handset is switched on right now.
