Non-Geographic Numbers (NGNs)

Non-geographic, or 'marketing' numbers are those prefixed with 0800, 0844, 0845, 0870 and 0871. Each prefix has an associated per minute rate which is either fixed or tied to a BT local/national rate.

There are a number of reasons for using marketing numbers:

• They provide a national, rather than local feel to a business
• The numbers are independent of location
• There are no line rental or connection fees
• Calls to these numbers may be forwarded to the office closest to the location of the caller
• Numbers need not be changed in the event of an office move
• Some prefixes offer a per-minute revenue share
• Unique numbers can be assigned to different marketing/advertising campaigns, meaning that campaign success can be tracked
