IMSI Lookup & Decoder

How Our IMSI Lookup Works

Our IMSI Lookup & Decoder tool analyzes a 15-digit International Mobile Subscriber Identity (IMSI) number to provide key details. When you enter an IMSI, our tool extracts the Mobile Country Code (MCC), Mobile Network Code (MNC), and the Mobile Subscriber Identification Number (MSIN). Using this information, we identify the mobile carrier, country of origin, and the types of networks it can connect to (like GSM, LTE, or 5G).

What is an IMSI?

The International Mobile Subscriber Identity (IMSI) is a unique identifier for a mobile subscriber on any cellular network. This number, typically 15 digits long, is stored on the SIM card and is essential for routing calls, messages, and data. It consists of three parts: the MCC (identifies the country), the MNC (identifies the mobile operator), and the MSIN (identifies the subscriber).
