Why do you need postcode data?

Postcode data can be a valuable asset to help expand your business. It can provide a variety of uses in many different aspects of business applications such as:

  • real estate
  • economic studies
  • location planning & analysis
  • address verifications

Postcode boundary data can be an essential tool for business in the UK today. Together with your own business statistics or other statistics such as census data, you can easily show spatial business trends.

The following example demonstrates how postcode regions can be used to evaluate sales regions of a company. Each sales region can be divided by postcode districts (noted by red boundaries & text). Sales statistics (purple text) within each postcode district can help identify and locate key sales figures for further evaluation. Automatically you can see which areas are performing well!

Adding census data as another layer, you can use postcode regions to determine which regions have more potential customers. For example, showing the number of people in each postcode region and the percentage of people earning over £30,000 per year can clearly identify target areas for sales.

The uses for postcode data in business are endless and it can be a valuable tool for marketing purposes.

Whatever you need in terms of UK postcodes, Global Mapping can provide it for you

What do you want to do?

Here is a list of questions asked by many of our customers along with the appropriate solution.

“I need a postcode map on paper”

We do postcode area maps of the UK on paper, encapsulated or as a Gif image. For District (e.g. NN13) or Sector maps (e.g. NN13 6) you can choose the part of the country, level of detail, paper size, scale and so forth through our Maps on Demand service. All maps can be previewed via the web before you confirm your order.

“I want a database list of postcodes for planning a direct mail campaign”

Order the PAF post office address file. This is a listing of the 2.1 million postcodes in the UK and the 26 million addresses that they cover. Typically provided as a comma separated (CSV) text file with all the various columns such as street, town, postcode and so forth. Most users have the listings by postcode, i.e. one record per postcode with a house number range, but by address is possible and more suitable for a mail merge.

“I want to use the Postcode database in my publicly accessible website”

You need the PAF file and/or PostZon files. but you also need a Royal Mail web use licence. This is charged either ‘per click’ or as a fixed annual fee. Per click means you need to submit a monthly statement of the number of postcode look-ups on your site. The fixed annual fee is more economic if you expect 400 000 or more look-ups in a year.

“I need a database of postcodes but with National Grid locations as I want to work out distances from one postcode to another”

Order the PostZon file, also PAF if you want full addresses. PostZon contains grid references to the nearest 100 metres for most postcodes other than P.O. Boxes. You also get details of the Ward, Health Authorities, etc that the postcode falls into.

“I want to map my sales territories and results using postcode sectors”

For this you need postcode geography in the form of objects that can be displayed in mapping software like MapInfo and ArcView. Postcode Area, District and Sector data in the form of polygons can be downloaded from our online shop. All objects are attributed, so can easily be joined to e.g. sales figures for each sector. As an optional extra we can provide counts of the number of addresses in each. This is ideal if you are building territories and want roughly the same number of prospects in each, or need to calculate the number of leaflets needed for a marketing campaign.

To order your data go to our online catalogue.
