☎️ Local 10-Digit Dialing Becomes Mandatory in Northern Ontario on May 31

Wednesday, 31 May 2023 08:00.AM

Starting May 31, 10-digit dialing will become mandatory for all local calls in northern Ontario, currently served by area code 807. Local calls dialed with seven digits will be interrupted by a network message asking the caller to hang up and redial using 10 digits – the area code and the seven digit number.

For Tbaytel Home Phone and Business Voice customers, Tbaytel is in the process of upgrading its existing landline and voice network necessary to support this change with the completion scheduled for later in 2023. Customers can visit for more details.

Residents and businesses need to add their area code to programmed numbers in all of their communications devices and equipment including wireline and wireless phones, auto dialers, computers, alarm systems and lifeline equipment. They should also include their 10-digit phone numbers on stationary, cheques, advertising, and update their employee, client, supplier, and other databases.
