the 900 area code was completely restructured by AT&T to be the premium-rate special area code which it remains today.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.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.
Numbers with the 900 area code were those which were expected to have a huge number of potential callers, and the 900 area code was screened at the local level to allow only a certain number of the callers in each area to access the nationwide long distance network for reaching the destination number.
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.
Diplomatic services, such as the US Embassy in London or the UK Embassy in Washington, have also charged premium rates for calls from the general public.
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.
A call to either one of these numbers can result in a high per-minute or per-call charge.
