Frequently asked questions
What is a phone validator?
Dexatel's phone number validator is a free tool that checks whether a phone number is real, active, and able to receive calls or texts.
It checks the number in real time against data from its mobile network operator and returns whether it's valid, along with its line type and carrier.
Is there a free phone number checker?
Yes. Dexatel's phone number checker tests a single number instantly and tells you whether it's valid, free and with no signup required.
For carrier, line type, country, network code and porting details, our Carrier Lookup tool returns the full picture inside your Dexatel account, which you can test with a free 30-day trial.
Can I validate a landline phone number?
Yes. Dexatel's validator checks any line type, including landline and mobile numbers.
Will I see who owns the phone number?
No. Dexatel's phone validator doesn't identify who owns a number. It only confirms whether the number itself is valid and reachable.
Can I validate personal and business phone numbers?
Yes. Dexatel's phone validator works on both personal and business numbers.
How accurate is Dexatel's phone number validation data?
Dexatel's phone validator uses real-time data supplied directly by the mobile network operator, the same source carriers use themselves, so results reflect the number's actual current status.
Will the phone number owner be notified when I validate their number?
No. Validating a number through Dexatel never notifies its owner. Dexatel operates in full compliance with Do Not Call regulations and the FCC's Telephone Consumer Protection Act (TCPA).
What's the difference between phone number validation and verification?
Validation confirms a number is real, active, and reachable using carrier data, with no action needed from the person who owns it.
Verification confirms someone controls a number, usually by sending a one-time passcode they enter back. Many teams validate a list first, then verify individual users at signup.
What is a ported number, and why does it matter?
A ported number is one that's been moved from one carrier to another while keeping the same digits.
Knowing a number's true current carrier matters for routing messages correctly and choosing the right channel, which is why Dexatel reports porting status in every check.
What does line type mean?
Line type tells you whether a number is a landline, a mobile, or a service number (a special-purpose line rather than a regular one).
It helps you decide how to reach a contact, for example sending an SMS only to numbers that can actually receive one.
