Phone Number Validator & Formatter

Understand a number, fix its format and check the cost to call — all in one place.

Check a phone number

Paste a + or 00 international number, or select a country for a local number. Spaces and brackets are accepted.

Validation runs in your browser. A separate rate check sends the number to TelHey for pricing.

What this check can’t tell you

Matching numbering rules does not prove that a number is assigned, active, owned by a particular person or reachable.

Carrier and live network status are not checked. The possible number type comes from numbering metadata, not a live carrier lookup.

Your country, length check, possible type and formatted number will appear here.
