. One exception is the Pacific Northwest, which used 1-1-3 until the mid-1980s. Until the early 1980s, 4-1-1 calls were free in most states.

4-1-1 has also been used for long-distance directory assistance in most areas in the United States and all of Canada. The traditional long-distance directory assistance number is 1-area code-555-1212.

4-1-1 is also commonly referred to as "D.A.", "Directory Assistance", or "Information". Prior to the introduction of Direct Distance Dialing (DDD) in the 1950s, which required dialing "1" to initiate a DDD call, the number for "Information" was 1-1-3 ("Repair" was 1-1-4). All existing local numbers beginning with 1 had to be changed, so "Information" and "Repair" (and others) changed to 411 and 611, respectively. Outside North America, "1-1-N" numbers are still in use, for these and other services.

Approximately 6 billion calls are made to 4-1-1 within the United States every year.

Some mobile carriers have tended to charge a lot for directory assistance calls placed to 411. Given this, competitive carriers have started to providing free service as long as the customer will listen to an ad played over the phone before receiving his or her requested number (e.g. 1-800-FREE-411
