787 area code — Santurce, PR geographic

Data: NANPA public reports, current as of July 28, 2026.

Phone numbers beginning 787 are registered to the Santurce area of Puerto Rico (Atlantic time zone). The code entered service on March 1, 1996. The same territory is also served by its overlay code (787/939 complex). Keep in mind the code identifies where the number was registered; the person calling may be elsewhere.

The code currently holds 777 working prefixes, held by 15 different carriers. Of these, 307 are pooled prefixes shared by multiple carriers. Numbers are anchored to 84 rate centers — billing localities that fix where each prefix belongs.

If a 787 call asks for money or personal data, treat the displayed number as unverified: hang up and reach the organization through its published number. Numbering data locates numbers, not callers.

The code was carved out of 809 (1996). As demand grew it in turn gave rise to 939 (2001).

The current NANPA exhaust forecast for the 787/939 complex is 2Q 2054.

Local calls inside 787 are dialed 10D.

FAQ

Why am I getting spam calls from 787 numbers?

Scammers spoof recognizable area codes so calls look local or familiar. A displayed 787 number does not prove the call originated there — see our guide to spotting spoofed calls.

Where is a 787 number from?

787 is assigned to Santurce and surrounding areas of Puerto Rico in the Atlantic time zone. The three digits after the area code (the prefix) narrow it down to a rate center.

Is 787 a toll-free number?

No. 787 is a geographic code; calls are billed like any other domestic call. Toll-free codes are 800, 833, 844, 855, 866, 877 and 888.
