Alberta area codes
Alberta uses 4 area codes, with 1 more assigned but not yet in service. The oldest is 403, in service since 1947; the newest is 825, from 2016. Across them 3,111 of 3,986 possible number blocks are allocated, 78.0% of capacity. 403, 780, 587 and 825 are at or past 95%, which is why new numbers there come from overlays rather than the original code. No single national carrier dominates: in 2 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 an Alberta caller ID 1,312 times – 0.6% of all complaints in the window, most often 587 with 390 (254th of 422 nationally). NANPA has relief planning under way for 568, so another code is coming. The CNA records 777 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 5 codes
| Code | In service | Blocks used | Largest holder | Complaints | Shares area with |
|---|---|---|---|---|---|
| 403 | 1947 | 781/800 | – | 359 | 368, 568, 587, 780, 825 |
| 568 planned | 2028-06-10 | 0/786 | – | – | 368, 403, 587, 780, 825 |
| 587 | 2008 | 779/800 | Other CLEC / VoIP 16.6% | 390 | 368, 403, 568, 780, 825 |
| 780 | 1999 | 780/800 | – | 356 | 368, 403, 568, 587, 825 |
| 825 | 2016 | 771/800 | Other CLEC / VoIP 8.7% | 207 | 368, 403, 568, 587, 780 |
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 Alberta’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
Most room left
568 is in service with no blocks assigned at all, so nobody can hold a number there yet – a caller ID showing one is necessarily spoofed.
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 | 2 codes | 2 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 Alberta codes
FTC Do Not Call complaints where the caller ID shown was a Alberta 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.
What is coming next
One code is assigned to Alberta but not yet in service. Numbers in them cannot exist yet, so a call displaying one today is spoofed.
NANPA has relief planning open for 568 – the step that comes before a new overlay is announced. Watch this code if you need to know whether dialing or new-number availability is about to change.
How Alberta got its codes
1 in the 1940s, 1 in the 1990s, 1 in the 2000s, 1 in the 2010s. Each code after the first was split off from or overlaid on one already in service.
- 1947 403 goes into service.
- 1999 780 goes into service.
- 2008 587 goes into service, split from or overlaid on 780.
- 2016 825 goes into service, split from or overlaid on 780.
- 2028 568 is due to go into service, overlaying 825.

Frequently asked about Alberta area codes
How many area codes does Alberta have?
4 in service, plus 1 assigned for the future (568). They are 403, 587, 780 and 825.
What is the oldest area code in Alberta?
403, 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 Alberta?
825, from 2016, overlaying 780.
Is Alberta getting a new area code?
Yes. 568 is assigned but not yet in service; 568 is due 2028-06-10.
What time zone is Alberta in?
Mountain time.
Which Alberta area code gets the most spam complaints?
587 – 390 FTC complaints in the 33 days to 30 October 2026, 254th 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 Alberta numbers?
No one carrier does. In 2 of the province's 5 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 Alberta?
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 Alberta have their own area code pages?
35 exchange areas are covered, from Calgary, Edmonton and Red Deer down to single-exchange towns. The CNA publishes exchange areas by name, so these are real places.
