- The 0500 range is used for some freephone services which were originally provided by Mercury Communications Ltd (now Cable & Wireless).
- Individual mobile phone companies are allocated different ranges within the 071 to 075,
07624 and 077 to 079 bands, but since the advent of mobile number portability,
mobile prefixes can no longer be relied on to determine the current operator of a particular mobile number - only the original operator.
- Many UK businesses employ numbers in the 03 and 08 range because of the benefits they can provide, such as fax to email
and virtual office applications. Also they are portable and don't depend on the business location.
- Revenue share was removed from 0870 numbers in 2009. Under Ofcom's "unbundled tariff" plans,
revenue share will be re-applied to 0870 in late 2014.
- Numbers beginning 084, 087 (except 0870 until late 2014), 090, 091 and 098
impose a Service Charge on all callers, to the benefit of the called party. The caller pays an Access Charge to
their own phone network as well as the Service Charge.
- All users of 084, 087 and 09 numbers must declare the Service Charge wherever their number is advertised.
- All phone networks must advertise a single Access Charge per tariff covering all 084, 087 and 09 numbers.
- Companies that can no longer justify revenue share or who fall under the restrictions listed in the Bill
on Consumer Rights are required to move from 084, 087 and 09 numbers to 01, 02, 03 or 080 numbers.
All numbers within the 034 and 037 ranges are already reserved for users to directly migrate from
the matching 084 and 087 numbers.
