Postal codes in the United Kingdom facts for kids
In the UK, special codes called postcodes help deliver mail to the right place. These codes are like unique addresses for every building or area. They use a mix of letters and numbers. For example, the postcode for the British Prime Minister's home at 10 Downing Street is SW1A 2AA.

What Are UK Postcodes?
UK postcodes are short codes that help sort and deliver mail. They are also used for many other things today. Each postcode points to a specific area, street, or even a single building. This makes it easy to find locations across the country.
How Postcodes Were Created
The idea for postcodes came from the Royal Mail, which is the UK's postal service. They started creating these codes in 1959. It took them 15 years to finish the whole system, finally completing it in 1974. The main reason for creating postcodes was to make sorting mail faster and more accurate, especially with machines.
The Postcode Address File
Today, all the UK postcodes are stored in a huge electronic list called the Postcode Address File. The Royal Mail keeps this file updated. It contains millions of addresses and their matching postcodes. This digital file helps businesses and services use postcodes easily.
More Than Just Mail
Even though postcodes were first made for mail, they are now used for many other important things.
- Finding Places: When you use a sat nav (like a GPS device) in a car, you can often type in a postcode to find your way. It's a very precise way to locate places.
- Insurance: Companies that offer insurance sometimes use postcodes to figure out prices. For example, car insurance might be different depending on the postcode where you live.
- Planning Services: Local councils and emergency services use postcodes to plan where to put things like schools, hospitals, or fire stations. They can see where people live and what services are needed in different areas.
- Business and Research: Businesses use postcodes to understand where their customers are. Researchers also use them to study populations and trends across the UK.
