Puerto Rico area codes
Puerto Rico uses 2 area codes. The oldest is 787, in service since 1996; the newest is 939, from 2001. Across them 1,136 of 1,572 possible number blocks are allocated, 72.3% of capacity. 787 is at or past 95%, which is why new numbers there come from overlays rather than the original code. Across the territory no single national carrier holds the most blocks: 48.4% sits with CLEC and VoIP holders counted together, ahead of Liberty at 26.4%. In the 33 days to 30 October 2026, FTC complaints named a Puerto Rico caller ID 47 times, most often 787 with 31 (395th of 422 nationally). NANPA records 159 rate centers across the territory's codes, and local calls take all ten digits.
All 2 codes
| Code | In service | Blocks used | Largest holder | Complaints | Shares area with |
|---|---|---|---|---|---|
| 787 | 1996 | 777/786 | Other CLEC / VoIP 53.2% | 31 | 939 |
| 939 | 2001 | 359/786 | Other CLEC / VoIP 38.2% | 16 | 787 |
Block share is share of allocated number blocks, not of subscribers. Complaint counts cover 28 Sep – 30 Oct 2026 and reflect spoofed caller IDs as much as real calls.
How full Puerto Rico’s codes are
A code holds at most 786 blocks of 10,000 numbers each. When a code fills up, the administrator does not reclaim numbers – it adds an overlay, and from then on new numbers in the same area come from the new code.

“Other CLEC / VoIP” is not one company: it is every holder outside the national carriers counted together, which is what resellers and app-based numbers look like in the records. This is allocation, not subscribers.
Spam complaints naming Puerto Rico codes
FTC Do Not Call complaints where the caller ID shown was a Puerto Rico number, 28 Sep – 30 Oct 2026 (33 days). Caller IDs on spam calls are routinely faked, so these are complaints about the code, not calls proven to come from it.

Which Puerto Rico area code gets the most spam complaints?
787 – 31 FTC complaints in the 33 days to 30 October 2026, 395th of 422 codes nationally. Those are complaints about the caller ID shown, and spam callers routinely fake a local-looking number, so this says the code is imitated often, not that the calls come from there.
Which carrier holds the most Puerto Rico numbers?
No one carrier does. 48.4% of the 1,136 number blocks assigned across Puerto Rico are held by CLEC and VoIP providers outside the national carriers – resellers and app-based numbers look like this in the records. The largest named carrier is Liberty with 26.4%. This is allocation of blocks by the numbering administrator, not a count of subscribers – people keep their numbers when they switch carriers.
Do you have to dial 10 digits in Puerto Rico?
Yes. Every code in the territory is in an overlay or ten-digit dialing area, so a local call needs the area code too. Dialing seven digits reaches a recording, not a wrong number.
