Is the phone carrier lookup really free?
Yes. The lookup is completely free and needs no sign-up or credit card. It runs on offline number-plan data, 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 line type (mobile, landline, VoIP, toll-free and more), the carrier or network where that data is published, the international and national formatting, and whether it looks like a real mobile or a virtual / VoIP line.
Why does the carrier sometimes show "Unknown carrier"?
We only display a carrier when the public numbering data positively identifies one. Many countries do not publish carrier-level number ranges, and number portability lets people keep a number when they switch networks. Rather than guess, we show "Unknown carrier" and still give you the country and line type, which we can verify reliably.
Can it tell if a number is VoIP or a real mobile?
It estimates the line type from the official numbering plan. A number assigned to a mobile range is shown as a real mobile, while numbers in VoIP / virtual ranges are flagged as VoIP. Because numbers can be ported, treat the VoIP flag as a strong signal rather than an absolute guarantee.
How many lookups can I do?
You get five free lookups every 24 hours per visitor. 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?
The lookup is processed on our own servers from offline data - the number you enter is not sent to any third-party API, and we do not build a public record of 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 public numbering plans, 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 the official numbering plan 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 range we show come from open, non-personal numbering 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 and offline - we never call, text or otherwise contact the number, and nothing is sent to any third-party service, so its owner gets no notification of any kind.
Why does my number show as VoIP when it is my real mobile?
Number portability is usually the reason: a number first issued in a VoIP or virtual range can keep that classification after it is ported, and some app-based or MVNO numbers sit in ranges flagged as VoIP. The flag is a strong signal from the official plan, not an absolute verdict - when the public data cannot confirm a network we say so rather than guess.
Can I look up several phone numbers at once?
The free tool is built for quick one-off checks - five 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 pings the live mobile network to report real-time status such as active, ported or reachable - it costs money and sends the number to a network. Our lookup is offline: it reads the public numbering plan to give you the country, line type and carrier range instantly and privately. It is the fast first check, but it does not report live active or disconnected status.
