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.Unlike a normal call, part of the call charge is paid to the service provider, thus enabling businesses to be funded via the calls.The industry still suffers from the stigma attached to the early days of the industry when adult entertainment lines were heavily advertised on late-night television commercials.

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.

These telephone numbers are usually allocated from a national telephone numbering plan in such a way that they are easily distinguished from other numbers.

Earlier, 976 numbers used 976 as a local prefix (970 or 540 in some markets like New York state), though it was not assigned to a specific telephone exchange like other prefixes.

These numbers were dialed as any other number, such as 976-1234.

Computer criminals have used premium-rate numbers to defraud unsuspecting Internet users.

One scheme involved inducing users to download a program known as a dialer that surreptitiously dialed a premium-rate number, accumulating charges on the user's phone bill without their knowledge.

Telephone companies typically offer blocking services to allow telephone customers to prevent access to these number ranges from their telephones.

In some jurisdictions, telephone companies are required by law to offer such blocking.

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.

the 900 area code was completely restructured by AT&T to be the premium-rate special area code which it remains today.

Another now-uncommon premium-rate scam involves television programming that induces young children to dial the number, banking on the notion that they will be unaware of the charges that will be incurred.
