Terms and definitions in messaging

Multichannel messaging service is based on a variety of telecommunication and Internet technologies. In the description of services, we often use abbreviations that may not always be known to you. Here we have compiled a glossary of terms and definitions used in the industry.


Mobile Country Code (MCC) is a 3 digit code used in combination with Mobile Network Code to identify a mobile network operator uniquely, the 1st refers the continent (the digits 1 and 8 are not used):

0: Test networks

2: Europe

3: North America and the Caribbean

4: Asia and the Middle East

5: Oceania

6: Africa

7: South and Central America

9: Worldwide (Satellite, Air-aboard aircraft, Maritime-aboard ships, Antarctica)

An MCC is used in combination with an MNC (a combination known as an “MCC/MNC tuple”) to uniquely identify a mobile network operator (carrier) using the GSM, UMTS, and LTE public land mobile networks. Some but not all CDMA, iDEN, and satellite mobile networks are identified with an MCC/MNC tuple as well.
