moving to www.telecom-tariffs.co.uk/codelook.htm
Please start using the new CodeLook page as soon as possible, it should be far more reliable than this old page.

30th June 2009 - The UK Telecom Tariff Cost Comparisons web site is moving from the Magenta Systems Ltd domain, to it's own http://www.telecom-tariffs.co.uk/ domain.  Both sites are currently duplicated with the same content, the old site will be dropped in a couple of weeks.  The new site uses a different back end server, which will ease many improvements planned for the next three months.  The only obvious difference at the moment is all pages with ASP URLs are now HTM instead.  For members, the login system has been improved so you will be remembered between visits and will only need to login once instead of separately for different parts of the site.  The main index pages now show if you are logged-in and allow log-off if the PC is shared. Logged-in members now have unrestricted access to Online CodeLook bypassing the daily usage restriction.


CodeLook has two main functions, looking up partial telephone numbers to find the locality and tariff band, and looking up localities tofind the code. It effectively replaces the BT Phone Book Companion that serves the same purpose in book format. The CodeLook database is updated approximately every one or two weeks.

This web site is duplicated at different hosting facilities for redundancy: Main Site CodeLook - Alternate Site CodeLook  Please bookmark the alternate in case the main site becomes unavailable. If both pages fail, please email Magenta Systems.

The partial telephone number can be national, international. mobile, premium, a service or indirect code. It may be a combined indirect code and partial number. For UK geographic telephone numbers, CodeLook can distinguish whether calls between two areas are local or national tariff band, if you specify your own telephone code. Once a telephone code has been found, next and previous buttons allow scrolling through the database. To protect the web server, the number of lookups is limited in each session. The Windows version available to members does not have any limit.

Operator: this is operator to whom the number range is allocated by Ofcom, but due to porting of numbers between operators, it is not necessarily the operator to whom the user pays their bill. 

Tariff Band/Tariff Code: this indicates the tariff band to which this number range has been allocated for end user billing purposes by BT.  The actual cost of calling this tariff band from a BT, Virgin Media (Telewest or NTL) residential line can be checked at Residential Telephone Tariffs - Part 1.  If you using a different operator to make calls, you need to look them up on the Residential Index page. Some non-geographic tariff bands show an indicative cost in pence per minute, this is what BT charges residential users for calls to this band and includes VAT at 15%, but note that other operators may charge more than BT, sometimes up to double.  If two or three prices are shown, these are usually the weekend/cheap/peak charge bands, but directory enquiries (DQ) numbers have a lot of charging permutations, more details of which can be found in the full tariff comparison tables.
