The way Puerto Rico got its area codes

For 5 years, 787 served Puerto Rico on its own, until 939 opened in 2001.

1996: 787 came into service as a new area code, covering Adjuntas, Aguada and Aguadilla.
2001: 939 was introduced as an overlay of 787, serving the same area.

How dialling works in Puerto Rico

In 787 and 939, a local call uses 10-digit dialling and a long-distance call uses 1 + the 10-digit number.
