How to Get a 748 Phone Number
There are three ways to get a phone number with the 748 area code, each suited to a different need:
- Buy from a premium-number specialist. Companies that hold curated inventories of specific area codes can sell you a 748 number directly, often with a one-time fee and ownership transferred to you (no recurring carrier fees). This is the option for picking a specific memorable number, or for getting an area code that most carriers won’t let you request. Contact us about a 748 number.
- Sign up with a VoIP carrier. Voice-over-IP services (such as Google Voice, OpenPhone, Grasshopper, and many others) can typically provision a 748 number on request, especially for active overlay codes. You won’t usually get to pick the specific number, but you’ll get a working line in the area code. This is the cheapest option for anyone who doesn’t need a particular number.
- Port an existing 748 number. If you already have a 748 phone number with another carrier, you can transfer it (port it) to a new service provider while keeping the number. This works for landlines, cell phones, and VoIP services, though landlines outside of Colorado sometimes can’t accept inbound ports of 748 numbers due to 911 routing rules.

Can I get a 748 number if I don't live in Colorado?

Is 748 a scam area code?
No. 748 is a legitimate, active area code for Western and Northern Colorado, including the Western Slope, Northern Colorado plains, and mountain communities. Like any area code, scammers occasionally spoof 748 caller IDs, but the code itself is heavily used by real Colorado businesses, government offices, and residents.
What area does the 748 area code cover?
Area code 748 covers the same geographic territory as area code 970 — western and northern Colorado, including Fort Collins, Grand Junction, Greeley, Loveland, Durango, Vail, Steamboat Springs, Glenwood Springs, Breckenridge, Aspen, and many other communities.
When did area code 748 go into service?
Area code 748 was placed into service on July 7, 2025, as an all-services overlay of area code 970. It became Colorado’s sixth area code.
Why was area code 748 created?
The 748 area code was created because area code 970 was projected to exhaust its available phone numbers by 2026. Rather than splitting the territory, regulators chose an overlay so all existing 970 customers could keep their numbers.
Do I need to dial 10 digits in the 748 area code region?
Yes. Because 748 overlays 970, all local calls within the region require 10-digit dialing — the area code plus the seven-digit number. Three-digit services such as 911, 988, and 211 are unaffected.
