The Canadian province of New Brunswick will use two area codes starting from November, 2020. Currently the province is served by NPA 506. The new area code 428 will also cover the entire province (the two area codes will overlay). As a result, 10 digit dialing will be used for all local calls within the area.
- August 13 to August 20, 2020 – permissive 7/10 digit dialing is introduced for local calls within NPA 506
- November 7 to November 14, 2020 – mandatory 10 digit dialing for local calls within NPA 506
- November 21, 2020 – the new area code 428 enters service
