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.
This practice continues, along with the use of these numbers for things such as software technical support, banking access, and stock tips.
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.
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.
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.
At that time, many evening news agencies conducted "pulse polls" for $.50 per call charges and displayed results on television.
