The country code for the United States is 1. The area code for Pittsburgh is 412. Two additional area codes—814 or 724—are prevalent in the suburbs.All U.S. telephone numbers consist of 10 digits—the three-digit area code, followed by a seven-digit local number. If you're calling a number from another area-code region, dial "1" then all 10 digits. If you're calling from a distance but within the same area code, dial "1" then the last seven digits. For calls within the same local calling area, just dial the seven-digit number. A map of U.S. area codes is printed in the front of most local telephone directories.Four special prefixes, "800," "888," "877," and "900," are not area codes but indicators of particular kinds of service. "800," "888," and "877" numbers can be dialed free from anywhere in the country—usually they are prepaid commercial lines that make it easier for consumers to obtain information, products, or services. The "900" numbers charge you for making the call and generally offer some kind of entertainment, such as horoscope readings, sports scores, or sexually suggestive conversations. These services can be very expensive, so know what you're getting into before you dial a "900" number.
Directory & Operator Information
For assistance from an operator, dial "0". To get a local or national telephone number, dial 411; in a few places it is necessary to dial 555-1212. If you want to charge a long-distance call to the person you're calling, call collect by dialing "0" instead of "1" before the 10-digit number, and an operator will come on the line to assist you (the party you're calling, however, has the right to refuse the call).
International calls can be direct-dialed from most phones; dial 011, followed by the country code and then the local number (the front pages of many local telephone directories include a list of overseas country codes). To have an operator assist you, dial "0" and ask for the overseas operator. The country code for Australia is 61; New Zealand, 64; and the United Kingdom, 44. To reach Canada, dial 1 + area code + number.
