New area codes
What are the new area codes in Canada?
New area codes will be introduced gradually in the following regions.
| Region | Current area code(s) | New area codes and 10-digit dialing to be added | Start date |
|---|---|---|---|
| Saskatchewan | 306, 639 | 474 | October 2, 2021 |
| Southern Ontario | 289, 365, 905 | 742 | October 16, 2021 |
| New Brunswick | 506 | 428 | April 29, 2023 |
What this means for you
Introducing a new area code in a region already served by another code creates only minor changes.
- Only new phone numbers are affected by the addition.
- Existing phone numbers keep the same area code and are not changed in any way.
- Local calling areas remain the same.
- The 9-1-1 emergency number remains a three-digit number throughout the area.
Why new area codes are needed
The introduction of new area codes is the result of decisions by the Canadian Radio-Television and Telecommunications Commission (CRTC) in response to the increased demand for communications services. New area codes allow for the creation of millions of new phone numbers.
