Area code 748

Where area code 748 is

748 is one of 6 geographic area codes serving Colorado; NANPA records its in-service date as July 7, 2025. It is an overlay: 748 and 970 cover the same territory, so neighbors on the same street can have different area codes. It is in the Mountain time zone.

Dialing 748 numbers

According to NANPA's dialing-plan data, local calls within 748 are dialed as ten digits (area code plus number) and toll calls as 1 plus ten digits. Because local calls need the area code, business cards, signage and website copy should always show the full ten-digit number. NANPA's dialing-plan note for this code reads: "1+10 digit permissible at service provider discretion."

A new code in an overlay

NANPA's utilized-code file dated 10/01/2026 lists no central office codes assigned in 748 yet. NANPA assigned the code on December 18, 2023 and put it in service on July 7, 2025. In an overlay, numbers for the shared territory keep coming from the older code (970) until carriers start drawing codes from 748, so a business phone number requested here today will most likely carry 970.

970 has been in service since April 2, 1995 and has 775 assigned codes held by 60 carriers across 120 rate centers. Its largest code holders are Qwest Corporation (189), Onvoy, LLC - CO (88), and Cellco Partnership d/b/a Verizon Wireless - CO (77). Its most populous matched places are Fort Collins (171,000), Greeley (114,000), Loveland (81,102), and Grand Junction (70,554).

Adding an overlay leaves existing numbers unchanged: nobody has to switch numbers, but local calls need all ten digits, and new lines can start with either code.
