The area codes 809, 829 and 849 are telephone area codes solely for the Dominican Republic. Following Saint Vincent and the Grenadines' leaving 809 in 1999, no other countries use the legacy 809 area code.When in the Dominican Republic, the 3-digit area code followed by the 7-digit phone number must be dialed. When calling the Dominican Republic from the United States or Canada, this must be prefixed by the digit "1". From other countries the international prefix used in the originating country must be dialled before the "1".
