MEID (Mobile Equipment Identifier) is a rare type of ESN (Electronic Serial Number) typically found on older devices. ESN numbers such as MEID are unique identifiers tied to all cellular devices. The most common type of ESN is the IMEI (International Mobile Equipment Identity).

No two devices should ever have the same ESN / IMEI / MEID, and reviewing this number is one of the most important steps in Swappa's listing review process. Thus, it's crucial to ensure that you provide the proper ESN when creating a listing on Swappa.
