Non-postal Uses and Economic Aspects
| This section requires expansion. |
While postcodes were introduced to expedite the delivery of mail, they are very useful tools for several other purposes, particularly because codes are very fine-grained and identify just a few addresses. Among uses are:
- Finding the nearest branch of an organisation to a given address. A computer program uses the postcodes of the target address and the branches to list the closest branches in order of distance as the crow flies (or, if used in conjunction with streetmap software, road distance). This can be used by companies to inform potential customers where to go, by job centres to find jobs for job-seekers, to alert people of town planning applications in their area, and a great many other applications.
- Postcodes can be used with satellite navigation systems to navigate to an address by street number and postcode.
- Postcodes are used by non-life insurance companies to assess premiums for motoring/business/domestic policy premiums.
- Postcodes are used by life insurance companies and pension funds to assess longevity for pricing and reserving.

Famous quotes containing the words economic and/or aspects:
“Our country has deliberately undertaken a great social and economic experiment, noble in motive and far- reaching in purpose.”
—Herbert Hoover (1874–1964)
“All the aspects of this desert are beautiful, whether you behold it in fair weather or foul, or when the sun is just breaking out after a storm, and shining on its moist surface in the distance, it is so white, and pure, and level, and each slight inequality and track is so distinctly revealed; and when your eyes slide off this, they fall on the ocean.”
—Henry David Thoreau (1817–1862)
