The more densely populated area of Colorado with the city of Denver and its extensive metropolitan area (Aurora, Bolder, Lakewood, Longmont and so on) is the only area in this state using an overlay complex comprising area codes 303 and its overlay code 720 (activated in 1998).
Once again the Colorado Public Utilities Commission is planning the introduction of a relief area code for this same geographic area: the new area code 983 is to overlay 303 and 720 NPAs starting next year in June. Local calls are already being dialed using 10 digits so there will be no other changes in the way calls will be dialed after the new 983 area code’s activation on June 17, 2022.
Approved all the way back in 1999 by the Illinois Commerce Commission (ICC), the new 464 area code will be added as a relief plan for Numbering Plan Area 708 which covers the area south of Chicago including these larger communities: Beecher, Berwyn, Chicago Heights, Cicero, Crest Hill, Crete, Hickory Hills, Oak Park, and so on. All calls in the area will be dialed using 1+10 digits with the activation of the new overlay complex 708/464.
A new area code was agreed upon by the Georgia Public Service Commission in October, 2020 to be added to one of the most complex overlay NPAs in the country: 404/678/470 and 770/678/470. These two NPAs cover the city of Atlanta and its surrounding metro area respectively (some example Atlanta metro area cities: Gainesville, Marietta, Sandy Springs).
The new 943 area code will, like the other two overlay codes 678 and 470, cover this entire area. Dialing arrangements will stay the same following the new area code’s activation.
The new area code’s 943 in service date: March 15, 2022.
The densely populated area surrounding the city of Toronto in southern Ontario, Canada will make use of a brand new area code beginning October 16, 2021. Currently, NPA complex 905/289/365 serves this geographic area, with cities such as Brampton, Hamilton, Missisauga or Niagara Falls.
A fourth area code 742 will therefore be added in October this year to cover the same geographic area served by the 3 aforementioned overlay codes. There will be no changes in the existing dialing plan for NPA 905/289/365:
all local calls will continue to be dialed using 10 digits
all toll calls will continue to be dialed using 1+10 digits
In order to meet the technical requirements for the activation by July 16, 2022 of the new 988 National Suicide Prevention and Mental Health Crisis hotline, a number of US numbering plan areas currently enjoying 7 digit dialing for local calls and also using 988 as a central office code (the 3 digits we dial after the area code) will have to migrate to 10 digit dialing. There is going to be a permissive dialing period during which people residing in towns and cities affected by this change can get used to the new dialing method.

In order to be able to activate the new 988 short dialing code, area codes (numbering plan areas) using both 7 digit dialing and 988 as a central office code are required to transition to 10 digit dialing by July 16, 2022.
In September this year The Public Service Commission of the District of Columbia approved an all services overlay as the relief method for NPA 202 – the area code serving the US capital city since 1947. The new 771 area code will cover the same area currently served by NPA 202.
