Area code 787 covers 84 rate centers across Puerto Rico. Communities served include Adjuntas, Aguada, Aguadilla, Aguas Buenas, Aguirre, and 79 more localities.

All numbers in the 787 area code observe Atlantic Time (IANA timezone: America/Halifax). Atlantic Time is UTC−4 in winter (AST) and UTC−3 in summer (ADT). When placing a call to a 787 number from a different time zone, check the current local time above to avoid calling outside of business hours.
From within Puerto Rico, dial the 7-digit local number directly if calling within the same rate center, or dial 1 + 787 + 7-digit number for long-distance calls within North America. From outside the US or Canada, dial your country's international exit code followed by 1 787 XXX XXXX. The country code for both the United States and Canada in NANP is +1.
Format 787 numbers using E.164 notation as required by RFC 3966: prefix with +1 and omit dashes and parentheses (e.g., +17875550100). This format ensures tel: links work correctly on all mobile browsers and VoIP apps. See the tel: URI formatting guide for complete examples.
