MEID stands for Mobile Equipment Identifier and is a unique identifier for a mobile device. MEID is a form of ESN (Electronic Serial Number).

MEID numbers often have multiple formats, MEID HEX and MEID DEC. The HEX value is a mix of letters and numbers and the DEC value is all numbers.

When an MEID is request, Swappa generally uses and asks for the MEID HEX, which looks something like this: A1000017F1000D

ESNs can have several formats, including the IMEI and the MEID.
