Phone numbers "from Denver" are, precisely speaking, numbers whose prefixes are anchored to the Denver rate center of Colorado, under 303, 720, 983.
NANPA records show 1,438 active prefixes here across 61 carriers. 768 prefixes participate in thousands-block pooling, so blocks of 1,000 numbers are shared between carriers.
The rate center belongs to the Denver-Aurora-Centennial, CO Metropolitan Statistical Area. Routing-wise it sits in LATA 656.
Multiple area codes over one rate center (303/720/983) is the overlay pattern: same geography, different first three digits.
At 1,438 prefixes — a ceiling of 14,380,000 numbers — Denver is one of Colorado's heavyweight rate centers.
As always with US numbering: a prefix anchored to Denver tells you where the block was issued. The person calling may have ported the number, moved away, or be spoofing it entirely — verify callers through independently found contact details.
