PR — Puerto Rico

Puerto Rico is an unincorporated territory of the United States in the Caribbean. San Juan, the capital, is one of the oldest European-established cities in the Americas. Puerto Rico has a unique political status — its residents are US citizens but cannot vote in presidential elections. Puerto Rico uses the US Dollar. For developers, the PR country code creates interesting classification challenges — it has its own ISO 3166-1 code despite being a US territory. The .pr domain supplements .com/.us usage. The +1-787 and +1-939 dialing codes follow the North American Numbering Plan. The es-PR locale handles Puerto Rican Spanish, which has distinct characteristics from other Latin American variants. Puerto Rico's status means it sometimes appears in country lists and sometimes doesn't, depending on whether the list includes territories. This inconsistency in country databases is a common source of bugs. Puerto Rico's Act 60 tax incentives have attracted many tech entrepreneurs, making it an important jurisdiction for US-based tech companies.
