For decades, most of the United States and Canada has used 4-1-1 as the telephone number for local directory assistance. One notable exception is the Pacific Northwest used 1-1-3 until the mid-1980s. In recent years, 4-1-1 has been used for long distance directory assistance in most areas in the United States. The traditional long distance directory number is 1-area code-555-1212. 411 is also used as a slang term meaning "information".
Since deregulation, the price of using 411 has increased to about $1.25 USD in the U.S., compared to $0.50 CAD in most of Canada. Many payphones still have the most basic form of local 411 free of charge, presumably because the customer will pay to call any numbers provided.
Three new services provide customers with a free alternative to the local-provider 411 service within the United States. 1-800-FREE-411 (1-800-3733-411) is the largest free provider of directory assistance and has captured approximately two percent of the directory assistance market*. Other free services include 1-800-411-METRO and 1-800-411-SAVE (1-800-411-7283). Each of these services are sponsored by local businesses and feature a brief recorded tag to identify the sponsor and its offerings.
