Premium Rate Service (PRS)
In the U.K., Premium Rate Service (PRS) is a telephone service that provides recorded information or live conversation for callers similar to 1-900 number service in the U.S. Callers are charged a higher rate on their phone bill, which is then split between the service provider and the network operator who leases the PRS number to the provider. PRS is a subcategory of Number Translation Service (NTS), and all PRS numbers begin with 090 with 0909 reserved exclusively for adult content services.
