WhatsApp Number Checker

This tool uses a third-party API to securely send the phone number you provide to WhatsApp's servers. It then receives a response indicating whether that number is currently registered and active on the WhatsApp network and displays the result to you.

The validator's accuracy depends on the real-time data provided by the API. It is generally very accurate for determining if a number is registered on WhatsApp at the moment of the check.

WhatsApp identifies users by their full international phone number, which includes a unique country code (e.g., 1 for the US, 44 for the UK, 91 for India). Without the country code, the system cannot locate the correct user. Do not include the + sign.

This tool does not store any phone numbers you enter. The number is passed directly to the verification service for the check and is not saved on our servers. However, as with any online service, you should be aware that the data is transmitted over the internet.

An error can occur for several reasons: the number might be formatted incorrectly, the verification service might be temporarily unavailable, or there could be a network issue. Please double-check that you've entered the number correctly (country code first, no spaces or symbols) and try again.
