Dialing into Puerto Rico means working with an open numbering plan under country code +1-787: a 3-digit prefix plus a 7-digit subscriber number, 10 digits total. Locally, numbers usually carry a leading "0" that gets dropped when calling Puerto Rico from outside the country.
Carriers & language
With 77% internet penetration, Puerto Rico is covered by 3 major carriers — Liberty Puerto Rico, T-Mobile Puerto Rico, Claro Puerto Rico. VoIP is permitted and regulated by FCC (Federal Communications Commission). IVR prompts, SMS copy, and business hours here should account for the local language (Spanish, English) and currency (USD).
Americas context
Numbering across the Americas mixes the North American Numbering Plan (+1) with national E.164 plans, so mobile and fixed-line prefixes vary from country to country.
Skipping the exit code
Puerto Rico calls from the US need 011 first, then +1-787 — the exit code isn't optional.
Keeping the national trunk "0"
Puerto Rico numbers often show a domestic leading 0 — drop it once you've dialed the +1-787 country code from outside the country.
Ignoring the time difference
Puerto Rico runs on UTC-4. Check local hours before dialing so calls don't land outside business time.
