Area code 906
Area code 906 is the telephone area code in the North American Numbering Plan (NANP) for the Upper Peninsula of Michigan.
History
Area code 906 was assigned in an area code split of numbering plan area (NPA) 616 on March 19, 1961, in a flash cut, which means no permissive dialing period was implemented. 906 is among the least populous numbering plan areas in North America, serving only about 320,000 people. Therefore, it is unlikely 906 will exhaust in the foreseeable future.[1] The area code has inspired an unofficial holiday in the Upper Peninsula on September 6 (906 correlating to the month/day date).[2]
Prior to October 2021, area code 906 had telephone numbers assigned for the central office code 988. In 2020, 988 was designated nationwide as a dialing code for the National Suicide Prevention Lifeline, which created a conflict for exchanges that permit seven-digit dialing. This area code was therefore scheduled to transition to ten-digit dialing by October 24, 2021.[3]
