Caguas, PR utilizes an area code overlay in which area codes 787 and 939 serve the same geographic area. Ten digit dialing (area code + seven digit number) is necessary because two different homes in the same geographic area can have the same seven digit phone number but each would have a different area code. The area code overlay which is in use today was put into service in 2001 when area codes 787 was overlaid with area code 939.
In addition to Caguas, PR area codes 787 and 939 serve all of Puerto Rico.
