A new area code is coming to the Denver metro area starting in April 2022, when available phone numbers starting with 303 and 720 are expected to run out.
The new 983 area code won’t be assigned until available phone numbers are exhausted, which the state expects to happen in the last quarter of 2022, according to Colorado’s Public Utilities Commission.
All current phone customers can keep their existing phone numbers and area codes. Starting in April 2022, people requesting new telephone service, or to move their service, may be assigned the new area code.
The change comes as Colorado’s population has exploded, with the state adding 1.5 million people over the last two decades. Most of that growth has been along the Front Range.
The 983 area code is expected to provide new phone numbers for about 25 years, according to the PUC.
This brings to five the number of Colorado area codes. The 303 and 720 area codes cover north-central Colorado, including the Denver metro area.
Colorado hasn’t had a new area code since 1998, when the 720 area code was introduced. The 303 area code served the entire state from 1947 to 1988.
