Converter

IMEI, MEID
and ESN.

Paste any of the three and we will convert it. MEID and ESN each split into two blocks that convert separately — which is why a plain base-16 conversion gives the wrong answer.

MEID: 14 hex or 18 digits · ESN: 8 hex or 11 digits · IMEI: 15 digits. We work out which you pasted.

Why converters disagree

It is two numbers,
not one.

A MEID is not a single value in base sixteen. It is a manufacturer block and a serial block, and each converts on its own — eight hex digits become ten decimal, six become eight. An ESN splits the same way, two and six.

Run the whole string through a plain hex-to-decimal conversion and you get a number that looks right and is wrong. That is the mistake behind most of the converters online, and it is why two of them will hand you two different answers for the same device.

Which one your phone has

IMEI, MEID, ESN — three eras.

  • IMEI — every GSM and LTE phone. Fifteen digits, the last one a check digit. If the phone takes a SIM, it has one.
  • MEID — the CDMA equivalent, used by Verizon and Sprint handsets before those networks moved to LTE. Fourteen hex characters. On a phone that does both, the MEID is simply the first fourteen digits of the IMEI, which is why one number converts into the other.
  • ESN — the original CDMA identifier, eight hex characters. The supply ran out and it was retired; anything sold in the last decade shows a pseudo-ESN instead, which always starts with 80 and is worked out from the MEID.

When a carrier form asks for a MEID and your iPhone only shows an IMEI, that first-fourteen rule is the answer — and the converter above does it for you.
