Line types
Mobile, landline, or VoIP
Every US and Canadian number belongs to a carrier, and carrier records say what kind of line it is.
Mobile
A number from a wireless carrier, tied to a SIM or eSIM in a phone. Most personal numbers are mobile.
Landline
A fixed line at a home or business address. Many landlines cannot receive text messages.
VoIP
An internet phone number from an app or online phone service, like Google Voice or a second-number app.

FAQ
Questions about VoIP numbers
- What is a VoIP number?
- A VoIP number is a phone number that runs over the internet instead of a SIM card or a copper line. It can call and text regular phones. Google Voice, Skype, and second-number apps all use VoIP numbers.
- How can you tell if a number is VoIP?
- Carrier records show which company runs a number and what kind of line it is. This tool reads those records. The area code alone cannot tell you, because VoIP numbers use the same area codes as mobile phones.
- Is a VoIP number a real phone number?
- Yes. A VoIP number is a real US or Canadian phone number. The difference is how calls reach it: over the internet, through an app or an online phone service.
- Can a mobile number become VoIP?
- Yes. People can move a number to a different carrier and keep it, so a number that started on a mobile plan can later run on a VoIP service. The checker shows the line type on file today.
- Does this show where the person is right now?
- No. It shows the region the number's area code belongs to. People keep their numbers when they move, and internet numbers can be used from anywhere, so the caller may be somewhere else.
- Will the person know I checked their number?
- No. The check reads carrier records and never calls or texts the number.
- How many numbers can I check?
- Region, local time, and area code details are unlimited. Line type checks are free up to 5 a day per person.
