Dominica

Dominica uses the +1 country calling code as part of the North American Numbering Plan, so international callers dial +1 followed by the local number. Its ISO 3166 codes are DM (alpha-2) and DMA (alpha-3), used in international shipping, data systems, and legal documentation. The country-code top-level domain (ccTLD) is .dm, available for website registration. The official currency is the East Caribbean dollar (XCD), shared with other OECS members, and is essential for pricing, banking, and trade within Dominica. These identifiers are vital for telecommunications, online presence, and financial transactions involving the island nation.
