These numbers were dialed as any other number, such as 976-1234.
A call to either one of these numbers can result in a high per-minute or per-call charge.
Also, the early incarnation of 900 was not billed at premium-rate charges, but rather at regular long distance charges based on the time of day and day of week that the call was placed.
The number used for the radio program was one that was specially arranged by AT&T Corporation, CBS Radio, and the White House, to be free to the calling party.
Unlike a normal call, part of the call charge is paid to the service provider, thus enabling businesses to be funded via the calls.
While the billing is different, calls are usually routed the same way they are for a toll-free telephone number, being anywhere despite the area code used.
Area Code 900 went into service January 1, 1971, but the first known to have been used in the United States for the "Ask President Carter" program in March 1977, for incoming calls to a nationwide talk radio broadcast featuring the newly elected President Jimmy Carter, hosted by anchorman Walter Cronkite.For free, you can sign up, upload hot photos and videos (and share them with those who catch your eye), and chat in various ways.Premium-rate telephone numbers are telephone numbers for telephone calls during which certain services are provided, and for which prices higher than normal are charged.One variant, targeted at children too young to dial a number, enticed children to hold the phone up to the television set while the DTMF tones of the number were played.This type of scam was especially popular in the late '80s to early '90s in the United States before tougher regulations on the 900 number business forced many of these businesses to close.At that time, the intent for area code 900 was as a choke exchange—a code that blocked large numbers of simultaneous callers from jamming up the long distance network.
