807 Area Code

Area code 807 covers all of Northwestern Ontario, Canada. Created in 1962 after splitting from area code 705, it serves a vast territory of roughly 526,000 square kilometres -- one of the largest geographic footprints of any area code in Canada. Major communities include Thunder Bay, Kenora, Dryden, Fort Frances, Sioux Lookout, and Marathon. The code spans two time zones: Eastern Time in the east (including Thunder Bay) and Central Time in the west (including Kenora). Incumbent carriers in the region include Tbaytel, Bell Canada, and Dryden Municipal Telephone Service.

The 807 region is the economic engine of Northwestern Ontario. Thunder Bay serves as the commercial, healthcare, and transportation hub for the entire northwest, with a port on Lake Superior that ships grain and commodities across the Great Lakes. Mining is the backbone of the wider regional economy -- Northwestern Ontario is home to active gold, palladium, and lithium projects, with Thunder Bay positioned as the primary mining supply and services hub. Businesses in natural resources, forestry, healthcare, and education (Lakehead University and Confederation College are both based in Thunder Bay) rely on local 807 numbers for client coordination, field dispatch, appointment management, and B2B outreach. A local number signals commitment to the community and consistently outperforms national or toll-free numbers in local answer rates.

Because 807 is the only area code in Northwestern Ontario -- with no overlay -- number availability is generally stable, and the Canadian Numbering Administration Consortium (CNAC) does not anticipate exhaustion for decades. That said, specific exchanges can fill up; check live inventory here. For businesses serving both the northwestern and northeastern Ontario markets, supplementing an 807 number with a nearby NPA like 705 can extend your regional coverage.

If you're targeting Thunder Bay or the wider northwest, display your number in both local and E.164 formats -- for example, (807) 555-1234 and +1 807 555 1234 -- to accommodate both local callers and inbound contacts from across Canada. Note that mandatory 10-digit local dialing came into effect on 15 January 2024, so all local calls within 807 now require the full area code. For SMS campaigns, register your traffic under Canada's applicable messaging guidelines. If you're porting an existing 807 number, check our porting guide -- most geographic numbers are transferable, and keeping the same number preserves customer familiarity.

10-digit dialing is mandatory within area code 807 as of January 15, 2024. For business SMS, follow Canadian carrier guidelines for commercial messaging. For cross-border operations into Minnesota via Fort Frances, note that US dialing rules apply (+1 country code required).

Area code 807 spans two time zones. Thunder Bay and the eastern portion of the region use Eastern Time (ET): UTC-5 in winter, UTC-4 during Daylight Saving Time. Kenora and the western portion use Central Time (CT): UTC-6 in winter, UTC-5 during Daylight Saving Time. Both zones observe DST, which runs from the second Sunday in March to the first Sunday in November.

Local 807 numbers consistently outperform toll-free numbers for answer rates with Northwestern Ontario contacts. If your business serves both northwestern and northeastern Ontario, consider pairing an 807 number with a 705 or 249 number to cover the broader region. Number availability in 807 is healthy given the region's low utilization rate.
