IMEI Check

Swappa verifies listings before they go live to prevent scams and keeps junk devices out. To do this, we need your IMEI if you’re selling a cellular device -- or your serial number if you’re selling a WiFi-only device.

Finding your IMEI is easy:

• iPhone and iPad IMEI numbers can be found by going to Settings > General > About
• MacBook serial numbers can be found by clicking About This Mac from the Apple Menu
• Android IMEI numbers can be found by going to Settings > About Phone > Status
