Area code 613

613 is eastern Ontario's area code, from Ottawa and the Ottawa Valley to Kingston, Belleville and Cornwall. It's one of Canada's original 1947 codes, and since 2010 it has shared its territory with 343, then 753. Gatineau, across the river, uses Quebec's codes.

Where 613 is used

The Canadian Numbering Administrator lists 132 exchange areas for 613 and its two overlays, grouped into eight regions named after Ottawa, Kingston, Belleville, Cornwall, Pembroke, Brockville, Smiths Falls and Hawkesbury.¹ The area runs from Bancroft and Trenton in the west to Hawkesbury and Lancaster at the Quebec border, and up the Ottawa Valley to Deep River and Rolphton.¹

131 of those exchange areas are in Ontario. One, St-Regis, is in Quebec and belongs to the Cornwall region.¹ Gatineau and Aylmer, across the Ottawa River, are exchange areas of 819, 873 and 468, in a region the administrator names after Hull.¹

Ottawa's own exchange area is called Ottawa-Hull in the administrator's list.¹ Lookup sites that read that list can show "Ottawa-Hull" for a 613 number, which doesn't mean the caller is in Gatineau.

From most of Ontario to the east end

When AT&T assigned the first area codes in 1947, Ontario got two: 416 and 613.³ 613 then gave up ground twice. 519 took parts of 416 and 613 in 1953, and 705 took parts of 613 and 519 in 1957.³

Until 2006, people could dial seven digits for local calls between 613 and 819, so an exchange prefix in use on one side of the Ottawa River couldn't be reused on the other. Mandatory ten-digit dialling in both codes, in October 2006, ended that restriction.³ The overlays followed: 343 in May 2010 and 753 in March 2022.^2,3

Exact dates are NANPA in-service dates. The administrator's history gives years or months.^2,3

When eastern Ontario needs a fourth code

The administrator's July 2026 forecast has 613, 343 and 753 lasting until May 2032, and the area isn't in relief planning yet.⁴ The next code is already chosen. In May 2025 the CRTC set aside 871 for eastern Ontario, when the forecast still pointed to March 2029.⁵

Projected exhaust dates from the administrator's status report posted Sept. 29, 2026.⁴

Like every overlay since 2001, 871 won't change anyone's number. New lines would start getting it once the CRTC sets a date.⁶

Calls from 613 numbers

Ottawa is the seat of the federal government, so a 613 number can look official. That makes it useful to scammers. The Canada Revenue Agency tells people not to trust the number on their call display. Ask for the caller's name, office and callback number, end the call, then check the number with the agency's verification tool before you call back.⁷

The CRTC says callers can display the number of a real person or organization, including government offices.⁸ The same checks apply to any 613 call that asks for money or personal details.

• Don't trust call display. The Canadian Anti-Fraud Centre says never to assume the number on your screen is accurate, for calls or texts.⁹
• Call back on a number you find yourself. If a caller says they're from your bank, a service provider, the police or a government agency, hang up and call the number on your card, your statement or the organization's website.^8,9
• Don't tap links in texts. Forward suspicious texts to 7726 (SPAM), then delete them.^9,10
• Report it. Report fraud to the Canadian Anti-Fraud Centre at 1-888-495-8501 or to your local police, even if you didn't lose money.^8,10
• Cut down on telemarketing. Register your number on the National Do Not Call List and file a complaint about unwanted telemarketing calls.⁸

What people are saying

We read Reddit threads that mention 613 numbers. The busiest recent one asks whether the CRA calls from them.

• "I looked up the number and it shows it's from Ottawa-Hull and with Roger's Communication."

  Poster on r/canadarevenueagency, Jan. 14, 2026¹¹

  Ottawa-Hull is the administrator's name for Ottawa's exchange area. It tells you where the number was issued, not who's calling.¹

• "Never ever believe that the number showing up on your phone is the actual number they are calling from."

  Commenter on r/canadarevenueagency, Jan. 14, 2026¹¹

  The CRA's own advice: "Do not trust the phone number displayed on your caller ID."⁷

• "and 753 starting this year"

  Commenter on r/ottawa, June 18, 2022, replying that Ottawa's codes are 613 and 343¹²

  Correct. 753 went into service on March 26, 2022.²

• "When the area codes were first created 416 was from Oshawa to Windsor. 613 covered the rest of the province."

  Commenter on r/askTO, March 27, 2024¹³

  Partly confirmed. The administrator's history shows Ontario had only 416 and 613 in 1947, and that 519 and 705 were later carved partly out of 613. It doesn't map the 1947 boundary.³

Claims we checked

• Out of date
  Eastern Ontario uses 613 and 343.

  Dialaxy's 613 page says that after 343 was added, "both 613 and 343 are used interchangeably for local numbers."¹⁴ It leaves out 753, which has been in service across the same area since March 26, 2022.^2,3

Questions people ask

How we did this

We counted exchange areas in the Canadian Numbering Administrator's listing dated Oct. 7, 2026, and took the history from the administrator's relief history and the NANPA database. The forecast comes from the administrator's Sept. 29, 2026 status report, and the set-aside code from CRTC Telecom Decision 2025-113. Advice on calls comes only from the CRA, the CRTC, the Canadian Anti-Fraud Centre and the Government of Canada. Reddit quotes are verbatim, with usernames left out. The clock uses fixed offsets and Ontario's 2026 time rules, not your device's settings.

Area codes change slowly, but new codes, forecasts and time rules do move. Each change goes in the update log below.
