We receive a daily update from every UK telecom licensed operator that contains all listed white pages telephone numbers. Ex-directory listings are not included and few mobile numbers are listed. Also available is the Royal Mail Postal Addess Finder (PAF) data and the current edited Electoral Roll.
About 49% of residential numbers are ex-directory or unlisted.
Other reasons include:
The data is updated daily and includes such things as amendments to existing records, newly inserted records and the removal of no longer required records - If the number is listed, we have it.
You can enter text as uppercase or lowercase, this site is not case sensitive. It will also ignore any punctuation e.g. O'Neill will be treated as oneill, d'arcy will be treated as darcy.
We apply a method of 'fuzzy' matching which in most cases will ignore any obvious spelling mistakes etc, but don't type too much. Typing too much increases the chance of a difference in the spelling of a name. Just try the last name and town/village etc to start with. You can always refine the search further if too many are found.
A wildcard is a character that forces the search to ignore part of the input. Suppose you were looking for someone called John Martinson. If you were to enter:
Name: mart*
Initials: j
Location: manchester
The search would return the following names: Martin, Martindale, Martinez, Martini, Martins, Martinz, Martlew and Martyn.
We need a location for residential searches but not for most business searches. The location can be the city, town, village, postcode or dialling code of the person or business you are searching.
If you are looking for a business with an unusual name, it may be quicker to do a national search, i.e. leave the Location box blank.
Here are some worked examples of how best to enter the search information:
Name: airship ball*
Location: (none)
Click on 
You may be looking for the number of a national company, but you don't know their location. We will return their national enquiry numbers.
Name: AA insura*
Location: (none)
Click on
Another example:- A colleague has lost their Barclaycard; find the emergency number:
Name: barc* lost
Location: (none)
Click on
We will return a small selection of numbers, including the one required.
Some businesses are hard to find; so use key words. For example, a colleague is an O2 customer, and needs to speak with them:
Name: o2 cust*
Location: (none)
Click on
We will return a small selection of numbers, including the one required.
If you are unable to locate a person, try using fewer letters, with the wildcard.
We offer the edited UK electoral roll. You can search for a person or persons by entering their name or just their address.
You can search the whole of the UK by leaving the location blank:
