Frequently Asked Questions

Do I need to dial 011 to call Puerto Rico from the US?

No. Since Puerto Rico is part of the North American Numbering Plan (NANP), you just dial 1 + Area Code (787 or 939) + Number, exactly like a long-distance call within the US.

What is the difference between 787 and 939?

There is no geographic difference. 787 is the original area code, and 939 was added as an overlay when numbers ran out. Both codes cover the entire island.

Is calling Puerto Rico free with my US cell plan?

It depends on your carrier. Most major US carriers (Verizon, AT&T, T-Mobile) include Puerto Rico in domestic plans, but some prepaid or MVNO carriers might charge extra. StartACall is a great alternative if you are calling from outside the US or have a plan that charges for PR.

How do I call Puerto Rico from outside the US?

Dial your country's international exit code (e.g., 00 in Europe), then 1 (US country code), then the area code (787 or 939), and the number.

Puerto Rico's Place in the +1 System: 787, 939, and Who Dials What

In short

Puerto Rico is a full member of the North American Numbering Plan, which makes dialing simple from the US mainland and only slightly different from everywhere else. This guide covers how the island got its two codes, the mainland versus international dialing paths, time zone quirks, and cost expectations.

From 809 to Two Codes of Its Own

For decades Puerto Rico shared the 809 code with much of the Caribbean. In 1996 the island received its own code, 787, and demand grew quickly enough that 939 was overlaid across the same territory in 2001. Both codes cover the entire island, from San Juan to Mayaguez.

Because 939 is an overlay rather than a region, the two codes carry no geographic meaning. A business in Ponce and its neighbor can hold numbers in different codes, and both are dialed identically. The code reveals when a number was issued, not where.

Dialing from the Mainland Versus Abroad

From the US mainland or Canada, Puerto Rico dials like any domestic number: 1, then 787 or 939, then seven digits. No exit code, no international format. Most US mobile and landline plans also rate these calls as domestic, though prepaid plans occasionally differ, so a quick plan check is worthwhile.

From everywhere else, treat it as a call to the United States. Dial your country's exit code, then 1 787 or 1 939 and the local number. Spain, with its deep family ties to the island, uses exit code 00, so a San Juan call from Madrid begins 00 1 787.

Within the NANP Caribbean no exit code is needed at all, since the whole region shares +1. From the Dominican Republic, the US Virgin Islands, or Jamaica, Puerto Rico is dialed as 1 787 or 1 939 plus the number, exactly as if you were calling Florida.

Clocks, Rates, and Mobile Numbers

Puerto Rico keeps Atlantic Standard Time all year and does not observe daylight saving. That places it one hour ahead of US Eastern Time in winter and level with it in summer, and four to five hours behind Western Europe depending on the season.

Mobiles on the island use the same 787 and 939 codes as landlines, and international rates treat the island as a US destination. On a pay-as-you-go service such as StartACall, one per-minute rate covers any Puerto Rico number, with no connection fee and credits that never expire.

Habits That Trip Up Callers to the Island

Puerto Rican numbers are always ten digits after the 1, and locals share them in full because the 939 overlay made ten-digit dialing mandatory on the island years ago. If someone recites seven digits from memory, ask which code applies instead of guessing, since 787 and 939 numbers coexist on every street.

For the diaspora, inbound matters as much as outbound. A US virtual number, available through StartACall for $2.14 to $5 per month, gives island relatives a mainland number to dial, while your outbound browser calls to Puerto Rico run on pay-as-you-go per-minute credit with no subscription and no connection fee.

Hurricane season occasionally disrupts island telecoms, and calls that fail in the days after a major storm usually reflect infrastructure rather than dialing errors. Mobile networks tend to recover first, so retry cellular contacts before fixed lines while the island is restoring service.

Frequently asked questions

Do 787 and 939 cover different parts of the island?+

No. 939 is an overlay across the whole island, added in 2001 when 787 numbers ran short. Both codes serve every municipality, so the code says nothing about location. Both work identically from any country.

Does dialing Puerto Rico from New York need 011?+

No. Puerto Rico is inside the North American Numbering Plan, so from anywhere in the US or Canada you dial 1, the area code, and the number, exactly like a call to another state.

Why does Puerto Rico never change its clocks?+

The island stays on Atlantic Standard Time year round with no daylight saving. It matches US Eastern Time in summer and runs one hour ahead in winter, worth remembering for standing calls.

How do I call San Juan from Spain?+

Dial 00, Spain's exit code, then 1 787 or 1 939 and the seven-digit number. Spain runs five to six hours ahead of the island, so evening calls from Madrid reach San Juan in the afternoon.

Are calls to Puerto Rico priced like US calls?+

On most international services, yes. The island shares the +1 country code and is typically rated as a US destination, with mobiles and landlines at the same per-minute price. Check the listed rate to confirm.
