Most U.S. mobile phone users will not pay roaming charges in Puerto Rico; confirm with your company. Area codes are 787 and 939. Toll-free numbers (prefix 800, 888, or 877) are widely used, and many can be accessed from North America (and vice versa). For North Americans, dialing Puerto Rico is the same as dialing another U.S. state or a Canadian province. To make a local call in Puerto Rico you must dial 1, the area code, and the seven-digit number. For international calls, dial 011, the country code, the city code, and the number. Dial 00 for an international long-distance operator. Phone cards are widely available (most drugstores carry them).
