Osaka’s geographic fixed-line area code is 06 domestically and +81 6 internationally.
An area code identifies a fixed-line numbering region, not an exact address or individual subscriber, and a region may include several municipalities. Area-code and subscriber-number lengths vary, so arbitrary regrouping can produce a misleading code. Mobile numbers beginning 070, 080 or 090 and IP-telephony numbers beginning 050 are non-geographic and are not included here.
