MEID check digit calculator

Client

Using the calculator

Paste or type the MEID. On pass, the trailing symbol matches Luhn on the body. On fail, the tool shows the digit that would validate the other positions.

Privacy: checksum math runs locally in your tab. Toolcore does not query carrier or TIA MEID databases—format and Luhn check only.
?
