DO — Dominican Republic

The Dominican Republic occupies the eastern two-thirds of Hispaniola island, which it shares with Haiti. Santo Domingo, the capital, is the oldest continuously inhabited European settlement in the Americas. The Dominican Republic has the largest economy in the Caribbean and Central American region. The Dominican Peso (DOP) uses the RD$ symbol. For developers, the DO country code must be distinguished from DM (Dominica). The .do domain has been used for domain hacking with words ending in 'do.' The +1-809 code (also +1-829 and +1-849) follows the North American Numbering Plan — the DR is notable for having three NANP area codes. The es-DO locale handles Dominican Spanish, which has distinctive features. The multiple NANP area codes (+1-809, +1-829, +1-849) complicate phone number validation since all three must be recognized as Dominican Republic numbers. The country's large diaspora, especially in New York, makes Dominican locale support important in US-based applications.
