A rate center is the telephone exchange area a number is homed to. It sets local calling boundaries, and is not the caller's current location.
428 was activated on Apr 29, 2023 as an overlay covering New Brunswick (province-wide). It shares the same geography as 506, which means ten-digit dialing is required for local calls in this region — dial the area code even when calling a neighbor.
A new 428 number does not indicate a different city than 506. Overlays are added when the existing code runs out of available prefixes.
See every North American overlayArea code 428 is a North American Numbering Plan (NANP) telephone area code assigned to New Brunswick, Canada. It is one of 2 area codes serving New Brunswick. As population and demand for phone numbers grew, the region was divided into multiple numbering plan areas to avoid exhausting the available 7-digit number pool.
Yes. 428 is an active North American Numbering Plan (NANP) area code, currently assigned to New Brunswick, Canada. It is safe to answer or dial calls using this area code.
Area code 428 covers 15 cities and communities in New Brunswick, including Bathurst, Bouctouche, Harvey Station, Miramichi, Moncton, and 10 more localities. This is based on telephone company rate center data — the geographic areas carriers use to determine local calling boundaries and to assign numbers when a business or individual requests a phone number in a specific city.
All numbers in the 428 area code observe Atlantic Time (IANA timezone: America/Halifax). Atlantic Time is UTC−4 in winter (AST) and UTC−3 in summer (ADT). When placing a call to a 428 number from a different time zone, check the current local time above to avoid calling outside of business hours.
From within New Brunswick, dial the 7-digit local number directly if calling within the same rate center, or dial 1 + 428 + 7-digit number for long-distance calls within North America. From outside the US or Canada, dial your country's international exit code followed by 1 428 XXX XXXX. The country code for both the United States and Canada in NANP is +1.
Format 428 numbers using E.164 notation as required by RFC 3966: prefix with +1 and omit dashes and parentheses (e.g., +14285550100). This format ensures tel: links work correctly on all mobile browsers and VoIP apps. See the tel: URI formatting guide for complete examples.
