New Ontario area code 753

In a decision dated November 10, 2021 the Canadian Numbering Administrator approved a second overlay Numbering Plan Area Code for the Canadian capital Ottawa and all the geographic area currently using area codes 613 and 343 (Brockville, Cornwall, Kingston..). This highly populated area of eastern Ontario has been using two area codes since 2010 , when area code 343 was overlaid on NPA 613.

The recently annouced 753 area code will be activated on March 26, 2022, forming overlay complex 613/343/753. Residents of this area already dial 10 digits for all local calls, therefore no changes will be introduced next year when the new area code 753 enters service.

See official NANPA planning letter including a map of the geographic area covered by the future overlay complex 613/343/753 (PDF document).

New Ontario area code 683

The central and north eastern portions of Ontario, Canada currently covered by NPAs 249 and 705 will soon get a brand new area code. The new 683 NPA was announced on November 10, 2021 by the Canadian Numbering Administrator as the relief plan for existing overlay complex 249/705, serving cities such as Orillia, Barrie, Peterborough or Sault Sainte Marie.

June 18, 2022 is the date when the new 683 area code is scheduled to enter service. Already served by 2 area codes, 10 digit dialing is currently compulsory for all local calls in this part of Ontario so no change in the way calls are dialed is to be implemented on June 10.

New Missouri area code 975

Area code 975 was scheduled to enter service in late 2001, but its activation was subsequently postponed indefinitely after the reevaluation of the need for a relief plan for Numbering Plan Area 816, covering the western portion of Missouri, with Kansas City, Independence, Lee’s Summit and Saint Joseph among the main locations served.

This year (2021) in August the Missouri Public Service Commission announced a new effective date for the introduction of the new area code 975, now scheduled to enter service on February 10, 2023, overlaying existing 816 area code and basically covering the exact same geographic area.

The dialing plan for the newly formed overlay complex 816/975 will be: 10 digits for all local calls and 1+10 digits for all toll calls (telephone service providers may also allow 1+10 digit dialing for local calls). This dialing plan is already in place for NPA 816 since October 24, 2021.

The activation of the new area code was later postponed indefinitely, while 10 digit dialing was in the meantime introduced for a number of area codes in October this year.

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.

These two NPAs cover the city of Atlanta and its surrounding metro area respectively (some example Atlanta metro area cities: Gainesville, Marietta, Sandy Springs).

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 and toll calls will continue to be dialed using 10 digits.
