The Correct Format For A Postal Address In Britain
Here’s a simplified guide to addressing mail in the UK:
Name of Recipient
House number, Street
Locality (if needed)
Town (ALL CAPS)
Full postcode (ALL CAPS)
One easy example is:
Mr John Smith
123 High Street
Little Village
LONDON SW1A 1AA
Follow these tips to address mail the UK way:
- Ditch full stops and commas
- Start each line to the left
- Write the town and country in caps
- Always add a return address
For international mail, don’t forget to add the country name (in English) as the last line of the address. Here’s how:
Ms Jane Doe
456 Main Street
Big City
ONTARIO L4B 1C2
CANADA
UK postal code
Understanding the UK postal code system is simpler than it seems!
It’s made up of two parts:
- The first part, with 2 to 4 alphanumeric characters.
- The second part, always with 3 digits.
The code starts with a letter or two for the postal area. After that, you’ll see some numbers indicating a location within that area. A space comes next, then a number for another sector within the previous area, and finally two letters related to the nearby streets and walkways.
Take this as an example:
GL51 0EX – The ”GL51” is the postal code for Cheltenham in Gloucestershire.
Compass directions (such as C, S, N, W, E, NE, NW, SE, SW) can represent locations too.
For instance:
SW15 5PU – This pinpoints to the University of Roehampton in the Southwest.
