Software version IMEI format check.

IMEISV format check

Checks 16-digit IMEISV length and Luhn check digit—does not query carrier databases. Processing runs in your browser—Toolcore does not need your paste for the core operation on this page.

Format and checksum rules only—no live registry lookup.

How to use

Paste or type in the main field, then read the output below. Use Load example when available, or open the page with ?q= / ?qb= so tickets and agents share the same input.
