What Is a MEID Number?

MEID stands for Mobile Equipment Identifier. Similar to an ESN, every phone has a unique MEID, much like every person has a unique fingerprint. The MEID system replaced the older ESN system for CDMA phones in the United States.

Carriers use MEID numbers to monitor account status, check for past-due bills, and identify devices that have been reported lost or stolen.

How to Find Your MEID

Your MEID can typically be found:

  • In your phone’s Settings menu (usually under “About Phone”)
  • On a label underneath or beside the battery
  • On the original device packaging

MEID Format

  • MEID numbers are 14 characters long, consisting of both letters and numbers
  • They use the number zero (0), not the letter “O”

What Is a “Bad” MEID?

A “bad” MEID means the phone cannot be activated. This usually happens when the previous owner has an overdue balance or the device was reported lost or stolen. To resolve a bad MEID, you’ll need to contact the carrier or the previous owner.

How to Verify Your MEID Is Clean

Before buying or selling a used phone, always verify the MEID is clean by contacting the carrier (call from a different phone):

  • Verizon: 1-800-922-0204
  • Sprint: 1-888-211-4727
  • US Cellular: 1-888-944-9400
