Free phone number checker

Check if a phone number is valid in any of 245 countries: mobile or landline, original carrier, location, time zone and the correct international (E.164) format. No signup.

What the checker tells you

Validity against each country's numbering plan, line type (mobile, landline, VoIP, toll-free), whether it can get SMS, the carrier the number range was first given to, location and time zone. Data comes from Google's open libphonenumber.

What it does not do

It does not query the live mobile network, so it cannot tell if a number is switched on or was ported to another carrier. For live line status, see the Twilio Lookup and 1Lookup comparisons.
