Learn about the new area codes and view the frequently asked questions.

As the demand for telecommunications services in Ontario continues to grow, 3 new area codes will be added between October 16, 2021 and June 18, 2022 to ensure adequate availability of telephone numbers. Specifically:

  • The geographic region currently covered by area codes 289, 365 and 905 will see the addition of a fourth area code, 742, on October 16, 2021
  • The geographic region currently covered by area codes 343 and 613 will see the addition of a third area code, 753, on March 26, 2022
  • The geographic region currently covered by area codes 249 and 705 will see the addition of a third area code, 683, on June 18, 2022

Notes:

  • The new area codes will be 683, 742 and 753, and will only be assigned to new telephone numbers
  • Anyone who already has a number with area code 249, 289, 343, 365, 613, 705 or 905 will keep the same number
  • The geographic boundaries that govern long distance will not change
  • Special numbers, like 9-1-1, will still be dialed using 3 digits

For the frequently asked questions, see below.

What are the new Ontario area codes?

The following new area codes will be introduced using an overlay method:

  • Area code 753 will be introduced gradually in the regions currently served by 343 and 613 in Eastern Ontario
  • Area code 683 will be introduced gradually in the regions currently served by 249 and 705 in Central Ontario
  • Area code 742 will be introduced gradually in the regions currently served by 289, 365 and 905 in Southern Ontario

When will the new area codes be introduced?

  • Area code 753 will be introduced starting March 26, 2022
  • Area code 683 will be introduced starting June 18, 2022
  • Area code 742 was introduced starting October 16, 2021

Will current phone numbers change?

No. Your current phone number will not change.

Will local and long distance calls be affected?

No. Local and long-distance calling will continue to be dialed in the same manner. For long distance calling, continue to enter 1 followed by the 10 digit number.

After the new area codes launch, will all new numbers have the new area codes?

No. Numbers will continue to be assigned with existing area codes until there are none left.

When will it be possible for businesses to reserve new numbers in area codes 683, 742 and 753?

The Canadian Numbering Administrator (CNA) will assign blocks of new numbers to telecommunications carriers only when all numbers in the existing area codes have run out. This could be long after the new area code launch dates, and will vary by area and telecommunications provider.

Numbers with the new area codes will only become available for reservation to customers after such numbers have been assigned to a telecommunications provider.

Who is responsible for the introduction of new area codes in Canada?

These measures are the result of decisions by the Canadian Radio-Television and Telecommunications Commission (CRTC). Local telecommunications providers are responsible for implementing the changes.

What is the "overlay method"?

The overlay method simply involves adding a new area code to the geographic region served by existing area codes. The multiple area codes will co-exist, providing for a substantial increase in available telephone numbers in the region without affecting existing 10-digit numbers. With the overlay method, calls to telephone numbers with a new area code will be either local or long distance calling. It is important to configure equipment properly to ensure calls will be completed.

Is it common to introduce new area codes to ensure there is no shortage of available telephone numbers?

Yes. Most regions in Canada require multiple area codes to accommodate demand for telephone numbers. Adding new area codes provides a substantial increase in available telephone numbers.

Should business CPE systems be programmed with the new area code?

Depending on the CPE used, programming may be required to accommodate incoming and outgoing calls accordingly prior to the new area code launch dates. This will ensure that you are able to make and receive calls without any interruption.

If you would like to open a billable MAC order to get TELUS to perform the programming changes for you, please contact us at 1-877-520-1212. If your CPE system is fully managed by TELUS, we will be proactively working on this programming change and there is no additional charge.
