The labyrinthine streets of London and the charming villages of the Cotswolds all share one thing in common: a reliance on the efficient British postal code system. These seemingly cryptic strings of letters and numbers, known as British postal codes, play a vital role in ensuring your mail reaches its intended destination. But what exactly do these codes represent, and how do they work?
british postal codes
British postal codes, introduced nationally between 1959 and 1974, are alphanumeric codes consisting of two parts: the outcode and the incode. The outcode, typically the first two or four characters, identifies a broader geographic area and postcode district. Think of it as a sorting area for your mail. The incode, the following three characters, further narrows down the delivery area to a specific street or even a single large building.
For instance, the code SW1A 1AA might designate Buckingham Palace within the larger St. James’s district (SW1A). The outcode (SW1A) directs the mail to the right part of London, while the incode (1AA) pinpoints the exact palace location.
Understanding these components is just the first step. British postal codes can get even more interesting with additional details:
-
Postcode areas:
The outcode’s initial one or two letters represent a vaster postcode area. For example, the code “EH” signifies Edinburgh.
-
Postcode sectors:
These are formed by combining the outcode, a space, and the first character of the incode. They offer a more granular level of sorting within a postcode district.
-
Non-standard codes:
Keep an eye out for unique codes like BR for “British Forces” mail or the single letter “X” for confidential government deliveries.
