Manitoba area codes
Manitoba uses 3 area codes. The oldest is 204, in service since 1947; the newest is 584, from 2022. Across them 1,400 of 2,400 possible number blocks are allocated, 58.3% of capacity. 204 is at or past 95%, which is why new numbers there come from overlays rather than the original code. No single national carrier dominates: in 3 of them the largest share of blocks sits with smaller CLEC and VoIP providers taken together. In the 33 days to 30 October 2026, FTC complaints named a Manitoba caller ID 615 times – 0.3% of all complaints in the window, most often 204 with 357 (274th of 422 nationally). The CNA records 407 exchange areas across the province's codes. Canadian number blocks are administered by the CNA rather than NANPA, so block counts come from a separate file with a different maximum per code (800, not 786).
All 3 codes
| Code | In service | Blocks used | Largest holder | Complaints | Shares area with |
|---|---|---|---|---|---|
| 204 | 1947 | 781/800 | Other CLEC / VoIP 72.5% | 357 | 431, 584 |
| 431 | 2012 | 584/800 | Other CLEC / VoIP 28.1% | 258 | 204, 584 |
| 584 | 2022 | 35/800 | Other CLEC / VoIP 28.6% | – | 204, 431 |
Block share is share of allocated number blocks, not of subscribers. Complaint counts cover 28 Sep – 30 Oct 2026 and reflect spoofed caller IDs as much as real calls. Canadian blocks are administered by the CNA; the maximum per code is 800 rather than 786.
How full Manitoba’s codes are
A code holds at most 800 blocks of 10,000 numbers each. When a code fills up, the administrator does not reclaim numbers – it adds an overlay, and from then on new numbers in the same area come from the new code.
Full or nearly full
Who holds the number blocks
Counted as the number of the province’s codes in which each holder has the largest share. Block-level totals are not available for Canadian codes, so we do not add per-code percentages into a province-wide figure – that would be an estimate dressed up as a measurement.
| Holder | Largest in | Appears in |
|---|---|---|
| Other CLEC / VoIP | 3 codes | 3 codes |
“Other CLEC / VoIP” is not one company: it is every holder outside the national carriers counted together, which is what resellers and app-based numbers look like in the records. This is allocation, not subscribers.
Spam complaints naming Manitoba codes
FTC Do Not Call complaints where the caller ID shown was a Manitoba number, 28 Sep – 30 Oct 2026 (33 days). Caller IDs on spam calls are routinely faked, so these are complaints about the code, not calls proven to come from it.
How Manitoba got its codes
1 in the 1940s, 1 in the 2010s, 1 in the 2020s. Each code after the first was split off from or overlaid on one already in service.
- 1947 204 goes into service.
- 2012 431 goes into service, split from or overlaid on 204.
- 2022 584 goes into service, split from or overlaid on 204.

Frequently asked about Manitoba area codes
How many area codes does Manitoba have?
3 in service. They are 204, 431 and 584.
What is the oldest area code in Manitoba?
204, in service since 1947. Every later code in the province was split off from or overlaid on an existing one.
What is the newest area code in Manitoba?
584, from 2022, overlaying 204.
Is Manitoba running out of numbers?
204 is at or past 95% of capacity, but NANPA has not opened relief planning for it, so no new code is announced.
What time zone is Manitoba in?
Central time.
Which Manitoba area code gets the most spam complaints?
204 – 357 FTC complaints in the 33 days to 30 October 2026, 274th of 422 codes nationally. Those are complaints about the caller ID shown, and spam callers routinely fake a local-looking number, so this says the code is imitated often, not that the calls come from there.
Which carrier holds the most Manitoba numbers?
No one carrier does. In 3 of the province's 3 codes the largest share of number blocks is held not by a national carrier but by smaller CLEC and VoIP providers counted together – which is what resellers and app-based numbers look like in the records. This is allocation of blocks by the numbering administrator, not a count of subscribers – people keep their numbers when they switch carriers.
Do you have to dial 10 digits in Manitoba?
Yes. Every code in the province is in an overlay or ten-digit dialing area, so a local call needs the area code too. Dialing seven digits reaches a recording, not a wrong number.
Which cities in Manitoba have their own area code pages?
10 exchange areas are covered, from Winnipeg, Brandon and Portage La Prairie down to single-exchange towns. The CNA publishes exchange areas by name, so these are real places.
