Phone and device

These tools check how a number is built. They run entirely in your browser and send nothing, because a phone number or an IMEI can be linked to a person.

The research file lives in this tab's session memory only.

Phone number format

Runs locally

Checks whether a number fits its country's numbering plan and shows the country, the calling code, the national, international and E.164 formats and the range type (mobile, fixed line, toll-free, premium and so on).

Sent: nothing. The number is read in your browser with the libphonenumber-js library and is not sent anywhere.

Two-letter country code, for example TR, DE or US. Used only when the number has no country code.

IMEI structure

Runs locally

Checks the length and the check digit of an IMEI or IMEISV and splits it into its parts. It does not look up the device.

Sent: nothing. The IMEI is checked in your browser and is not sent anywhere.
