Historical Overview of 428 New Brunswick Area Code
The 428 area code was introduced in New Brunswick, Canada, on April 29, 2023, as an overlay to the existing 506 area code to meet growing demand for telephone numbers driven by increased mobile usage, internet services, and business expansion.
The Canadian Radio-television and Telecommunications Commission (CRTC) approved the overlay following long-term numbering relief planning that began in the mid-2010s, with formal approval issued in August 2018 and later scheduling updates refining the rollout. In preparation for the change, mandatory 10-digit dialing for all local calls in New Brunswick was implemented in January 2023 to support the transition from 7-digit dialing and ensure compatibility between 506 and 428 numbers.

428 Area Code: Dialing Format, Prefixes & Network Coverage
The 428 area code in New Brunswick, Canada, follows a 10-digit dialing format, which requires dialing the area code along with the 7-digit number for local calls. For long-distance calls within Canada or the U.S., the format is 1 + 428 + XXX-XXXX. Moreover, the international format remains the same, adding the exit code (or +) before 1 at the beginning.
The 428 area code operates under the North American Numbering Plan (NANP) and serves as an overlay to the original 506 area code. The province’s telecommunications network is supported by major providers such as Bell Aliant, Rogers, Telus, and Eastlink, with assigned prefix examples (NPA-NXX) in the region, including 428-208, 428-300, 428-880, and 428-910.
