The numbering plan area was designated in 1947, when the American Telephone and Telegraph Company (AT&T) devised a comprehensive telephone numbering plan for the United States and Canada. Before October 2021, area code 605 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. Area code 605 was therefore scheduled to transition to ten-digit dialing by October 24, 2021. Projections of 2023 suggested that South Dakota's numbering plan area will require relief action to avoid exhaustion of central office prefixes by late 2026. Such actions were taken, and the deadline is now extended to a projection of 2033. ==Service area== The numbering plan area includes the following communities, which are serviced by the listed central office prefixes.
