Each area code has 7,920,000 different usable phone numbers. (Although there are technically 10 million seven-digit phone number combinations available in each area code, some numbers aren't available, such as 911, 411, and numbers starting with 0 or 1.)
Facing a shortage of telephone numbers -- ''number exhaustion'' to use the industry term -- regulators are adding area codes at a furious pace. Since 1995, 138 area codes have been added around the country, raising the national total to 344. Between 1984 and 1994, the nation made do by adding only nine. In certain populous areas, including metropolitan New York and Boston, new area codes are often interspersed among existing ones.
