What is an IMEI number and how do I find it on my phone?
The IMEI (International Mobile Equipment Identity) is a unique 15-digit serial number assigned to every cellular device worldwide.

What is the difference between a Clean ESN and a Clean IMEI?
In the United States, Clean ESN (Electronic Serial Number) and Clean IMEI are interchangeable terms used by carriers and marketplaces (like Swappa and eBay). Both confirm that a smartphone is free from carrier financing debts, has no reports of theft or loss, and is immediately eligible for carrier activation and trade-in.
