In some jurisdictions, telephone companies are required by law to offer such blocking.
Adult chat lines (phone sex) and tech support are a very common use of premium-rate numbers.
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.
In many European countries, for example France, Germany and the United Kingdom, it was common for organisations to operate customer service lines on premium-rate numbers using prefixes that fall outside the scope of the country's premium-rate number regulations.
Therefore, in contrast to North America where customer service numbers are typically free of charge to the caller, consumers in Europe often used to pay a premium above the cost of a normal telephone call.
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.These telephone numbers are usually allocated from a national telephone numbering plan in such a way that they are easily distinguished from other numbers.Telephone companies typically offer blocking services to allow telephone customers to prevent access to these number ranges from their telephones.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.
For example, a "psychic hotline" type of 1-900 number may charge .99 for the first minute and 99 cents for each additional minute.
