Phone Validator ✔️ | Is it a Cell or is it a Landline? Phone Number Checker

Real customers have real phone numbers

Fake numbers waste your team’s time. Landlines can’t get your texts. And you can’t tell either one just by looking. Check a single number free right here, clean up a whole list, or check every number as it comes in.

Works with All Line Types

Is it a cell phone or landline? Our phone number lookups determine phone line type (mobile, landline, toll-free or VoIP) and identify the carrier and number origin.

Mobile
Landline
VoIP
Toll-free

Our phone number lookups also identify toll-free numbers and check for fake or invalid numbers.

How do I check a phone number?

Enter a phone number above and select Check phone number. See its line type, carrier and number origin, including whether it is identified as fake or invalid. This checks the number, not who owns it.

Can I identify Google Voice or TextNow numbers?

Yes. Our phone number checker can identify Google Voice, TextNow and other VoIP providers. Check Phone Line Type and Phone Company in your results.

Does phone number validation verify the owner?

A lookup checks number information. It does not prove that the person entering it controls the phone.

Understand phone number validation vs. verification

Where is a phone number from?

Number origin is based on the number’s area code and prefix. It does not show the phone’s current location.
