Puerto Rico Country Code

How do I dial mobiles vs landlines in Puerto Rico

Puerto Rico is part of the North American Numbering Plan (NANP), so it uses country code +1 and the area codes 787 and 939. Practically, that means calling Puerto Rico looks like calling any US-style number: +1 787 XXX XXXX or +1 939 XXX XXXX. The important thing for users is that 787 and 939 cover the same territory (an “overlay”), so you may see either area code for the same city or neighborhood. Because of this overlay, 10-digit dialing (area code + 7 digits) is standard, even for many local calls. 

There’s also no special “mobile format” vs “landline format” in Puerto Rico—both follow the same +1 + area code + 7-digit number structure. So the difference between mobiles and landlines is mostly about which carrier provides service, not how you dial. For the most reliable calling and messaging (especially when traveling), save contacts in E.164 format as +1 787… or +1 939… so your phone routes the call correctly from anywhere. 

What are the mobile operators in Puerto Rico

Because Puerto Rico follows NANP rules and supports number porting practices, you generally can’t identify the current mobile operator from the number alone. For users, the best rule is simple: always store and dial the number as +1 787… or +1 939… and let the network route it. Major mobile operators are:

• Claro Puerto Rico

• Liberty Puerto Rico

• T-Mobile (Puerto Rico)
