Mobile vs landline in Puerto Rico

Puerto Rico sits inside the North American Numbering Plan and shares the +1 country code with the United States and Canada, so a Puerto Rico number looks and dials exactly like a US one. Two area codes, 787 and 939, overlay the entire island rather than splitting it geographically — 939 was added when 787 ran short of numbers, so neither one tells you where on the island a number is. Unlike most countries, Puerto Rico does not separate mobile and landline into distinct number ranges; both sit under the same two area codes, and the only reliable way to tell them apart is by carrier lookup. For callers in the United States and Canada, Puerto Rico is normally billed as a domestic call rather than an international one.

Saving money on calls to Puerto Rico

Puerto Rico runs on Atlantic Standard Time (UTC-4) year round and does not observe daylight saving, so it matches US Eastern time in summer and runs one hour ahead in winter — worth checking before scheduling a call from the mainland. Business hours are typically 9 AM to 5 PM AST, Monday to Friday. Because Puerto Rico is inside the NANP, calls from the US and Canada usually carry domestic rather than international rates; from elsewhere, dialing over the internet avoids the international surcharge most carriers apply to +1 destinations.
