About 983 Area Code
Area code 983 serves Denver and north-central Colorado. Introduced in June 2022 as an overlay to 303 and 720, the code covers major population centers including Denver, Aurora, Boulder, Lakewood, Westminster and Thornton, spanning Denver, Boulder, Jefferson, Arapahoe, Adams and Douglas counties. The code supports local voice and SMS-capable numbers used by businesses, tech firms, healthcare providers and service organizations across urban and suburban communities.
The 983 region combines tech innovation (Google, Amazon, Twitter), aerospace manufacturing, energy research, and a booming financial services sector. Local businesses use 983 numbers for customer support, tech helpdesks, scheduling, sales outreach and field service coordination. These local numbers deliver higher answer rates than toll-free alternatives because they signal a regional presence and match customer expectations in one of the fastest-growing metro areas in the U.S.
FoneSwift lists live 983 inventory and capabilities on this page. Search numbers to see which ones support Voice, SMS and MMS. Because 983 is a newer overlay, availability can vary. If a local 983 number is not available immediately, similar results in overlays 303 or 720 serve the same geographic area and deliver equivalent local presence for metro Denver audiences.
If your business targets Denver or the Front Range, publish numbers in both local and E.164 formats (e.g., (983) 555-1234 and +1 983 555 1234) and register messaging traffic if you plan A2P campaigns. For porting, see our porting guide. Many businesses keep the same number to preserve customer familiarity and brand continuity in this competitive market.

How Does Local 983 Phone Numbers Work?
A local business number is a structured telephone identifier that tells networks where to route calls and messages. When you use a 983 number in Denver and Colorado, the digits signal the international gateway, the geographic region, the local exchange and the specific subscriber, so calls reach the right destination quickly and reliably.
The typical parts of a United States local number are:
- Country code (+1): identifies United States for international routing.
- Area code (983): directs the call to the Denver / Colorado region.
- Central office / exchange (eg. 555): narrows the call to a local switching area or rate center.
- Subscriber number (eg. 1234): the unique line assigned to a person, extension, or device.
