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.
