Minnesota area codes
Minnesota uses 8 area codes. The oldest is 218, in service since 1947; the newest is 924, from 2024. Across them 3,757 of 6,288 possible number blocks are allocated, 59.7% of capacity. 507 is at or past 95%, which is why new numbers there come from overlays rather than the original code. Lumen holds 28.3% of the 3,757 assigned blocks across the state, ahead of Verizon at 12.7%; a further 18.4% sits with CLEC and VoIP holders outside the national carriers. In the 33 days to 30 October 2026, FTC complaints named a Minnesota caller ID 1,915 times – 0.8% of all complaints in the window, most often 651 with 377 (258th of 422 nationally). NANPA records 639 rate centers across the state's codes.

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.
How full Minnesota’s codes are
A code holds at most 786 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
924 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 from every assigned block in the state: 3,757 blocks, each with the holder NANPA recorded for it. Percentages are measured, not estimated.
| Holder | Blocks | Share of Minnesota | Largest in |
|---|---|---|---|
| Lumen | 1,064 | 28.3% | 4 codes |
| Other CLEC / VoIP | 691 | 18.4% | 3 codes |
| Verizon | 477 | 12.7% | – |
| T-Mobile | 343 | 9.1% | – |
| Onvoy | 325 | 8.7% | – |
| AT&T | 281 | 7.5% | – |

“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 Minnesota codes
FTC Do Not Call complaints where the caller ID shown was a Minnesota 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.
