Three-way split of area code 612 announced

The North American Numbering Plan Administration assigned new area codes 763 and 952 on November 29, 1999, for a three-way split of area code 612 to relieve number exhaustion in the Twin Cities area.

Three-way split of 612 creating 763 and 952

Due to continued growth and number demand, area code 612 was split in 2000 into three parts: Minneapolis and nearby suburbs retained 612; northwest suburbs received 763; southwest suburbs received 952. This split followed municipal boundaries rather than exchange boundaries.

NPA 952 split from 612

Area code 952 was created on February 15, 2000, as part of a three-way split of 612. The southwest suburbs of Minneapolis, including Bloomington, Eden Prairie, and Minnetonka, were assigned to 952.

NPA 952 split from 612

Area code 952 was created on February 27, 2000, as part of the three-way split of area code 612, serving the south and southwest suburbs of Minneapolis.

Permissive dialing begins for 763 and 952

A permissive dialing period began on February 27, 2000, allowing calls to be completed using either the old 612 code or the new 763 and 952 codes for numbers in the affected areas.

Mandatory dialing for 763 and 952

Mandatory dialing of the new area codes 763 and 952 began on January 14, 2001, ending the permissive period for most customers. Calls dialed with the old 612 code for numbers in the new NPAs were routed to intercept.

Extended mandatory dialing for alarm customers

For burglar and fire alarm customers, the permissive dialing period for area codes 763 and 952 was extended until November 1, 2001, after which mandatory dialing of the new codes was required.

Ten-digit dialing becomes mandatory in NPA 952

Ten-digit dialing became mandatory in area code 952 on October 24, 2021, due to the nationwide designation of 988 as the three-digit code for the National Suicide Prevention Lifeline. This change was required to resolve conflicts with existing seven-digit dialing in exchanges using 988 as a central office code.

NPA 952 projected exhaust date

NANPA projections published in April 2025 estimate that area code 952 will not exhaust its numbering resources until the year 2236, indicating a long-term surplus of available numbers.
