Who Controls Colorado Area Codes?
Colorado area codes identify the areas, in the state, where incoming calls originate. These areas are represented by area codes and each location has its own unique code. A good way of filtering suspicious phone numbers that call your phone is to learn the various area codes in the state. That way, you can identify and ignore calls that are from areas you do not know. You can also use reverse phone lookup to identify unknown callers.
There are four area codes in Colorado, listed below:
The Colorado Public Utilities Commission controls area codes allocated to the state and makes all decisions related to the implementation and maintenance of area codes. It creates new area codes when current ones are almost exhausted by assigned phone numbers. Currently, there are three distinct area codes and one overlay code in Colorado.
