Colorado Phone Numbers and Area Codes

Phone numbers in Colorado consist of a three-digit area code followed by a seven-digit local number. The area codes used in Colorado include 303, 720, 983, 719, and 970. These area codes help in identifying the specific geographic region or city associated with the phone number. For example, the 303 and 720 area codes are primarily assigned to the Denver Metropolitan Area, while the 970 area code covers the northern and western parts of the state, including cities like Fort Collins and Grand Junction. The 719 area code is used for the southeastern part of the state, including cities like Colorado Springs and Pueblo. The 983 area code is a future area code reserved for when the existing codes are exhausted.
