What are the MCC and MNC codes in Japan?
Every mobile network in Japan shares Mobile Country Codes (MCC) 440 and 441 — the three-digit prefix that opens every PLMN broadcast by a Japan SIM. The country's international dialling prefix is +81, which is distinct from the MCC: 440 / 441 identifies the country inside the network, while +81 routes voice calls. Under ISO 3166 Japan is coded JP / JPN / 392. This page lists 41 mobile networks across 54 PLMN codes operating in Japan, with each network's MNC, full PLMN, operator, status and market share.
By reported market reach, the largest networks in Japan are NTT docomo (45.4%), au (33.2%), au (33.2%).
