'09' number call costs
The cost of calling an '09' number includes a service charge, which can be up to £3.60 per minute and/or £6.00 per call which is used to fund the service provided, and a standard access charge made by the caller's phone company. A wide range of charges is in operation and many numbers operate much lower charges than the maximums quoted above. By law, whenever an '09' premium rate service number is advertised, the service charge that applies must be clearly shown.

Adult content numbers in the ranges '0908' and '0909' are no longer being issued, but existing services can retain them.
History of '09' numbers
Premium rate numbers beginning with '09' were introduced in 1998 and eventually replaced a variety of older premium rate prefixes such as '0331', '0660', '0891', '0898' and '0991'. The first prefixes issued in 1998 were '0900', '0901', '0906', '0907' and '0909'. Adult services with sexual content were originally confined to the '0909' prefix and later expanded into '0908'. However, since 2005, all new services of this type use numbers beginning with '098', to aid recognition.
