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.
683 was activated on Jun 18, 2022 as an overlay covering Ontario (north and central). It shares the same geography as 249 and 705, which means ten-digit dialing is required for local calls in this region — dial the area code even when calling a neighbor.
A new 683 number does not indicate a different city than 249 or 705. Overlays are added when the existing code runs out of available prefixes.
See every North American overlayArea code 683 is a North American Numbering Plan (NANP) telephone area code assigned to Ontario, Canada. It is one of 19 area codes serving Ontario. 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. 683 is an active North American Numbering Plan (NANP) area code, currently assigned to Ontario, Canada. It is safe to answer or dial calls using this area code.
Area code 683 covers 58 cities and communities in Ontario, including Alban, Algoma Mills, Algonquin Park, Alliston, Apsley, and 53 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 683 area code observe Eastern Time (IANA timezone: America/New_York). Eastern Time is UTC−5 in winter (EST) and UTC−4 in summer (EDT). When placing a call to a 683 number from a different time zone, check the current local time above to avoid calling outside of business hours.
From within Ontario, dial the 7-digit local number directly if calling within the same rate center, or dial 1 + 683 + 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 1 683 XXX XXXX. The country code for both the United States and Canada in NANP is +1.
Format 683 numbers using E.164 notation as required by RFC 3966: prefix with +1 and omit dashes and parentheses (e.g., +16835550100). This format ensures tel: links work correctly on all mobile browsers and VoIP apps. See the tel: URI formatting guide for complete examples.
