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 information
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! Click on the image for a larger version.

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.
