This page connects featured cities in Okayama Prefecture with their published or clearly qualified telephone numbering associations.
“Largest” refers to the priority city set used by this directory. It is not a live population ranking.
Use the leading 0 in Japan and remove it after +81. For example, 03-1234-5678 becomes +81 3 1234 5678, while 045-123-4567 becomes +81 45 123 4567. The international access prefix used when dialling out from Japan is 010, sometimes following a carrier-selection code.

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.
A code listed beside a city reflects a featured numbering association; it does not assert that every community in Okayama Prefecture uses that code or that the code stops at the administrative border.
This release includes 1 verified or clearly qualified code association for the featured cities in Okayama Prefecture.
