Why use a postcode finder?

A letter or package to be delivered to someone’s home must have a postcode. But what exactly is a postcode and what is the easiest way to find it? The postcode was adopted in the UK between October 1959 and 1974 and is a series of two alphanumeric codes. The first part exists of two to four characters and the second one always has three characters. This special combination of characters ensures that the automatic sorting machines can process the mail correctly and that your mail is sent to the right province.

Without the correct postcode, the mail you send will be delivered too late. In the worst case, your mail may never arrive. In addition, the postcode is increasingly used by companies conducting marketing research. By asking customers for their postcode, they know in which areas their customers live.

How to find the right postcode

Nowadays, finding the right postcode for the letter you want to send is a lot easier than it was a few years ago. It was and is almost impossible to guess the correct postal code without help, and if the postal code is indeed given incorrectly then there is a chance that your letter or parcel simply will not be delivered by the postman.

That is why you can now use the postcode finder on the Royal Mail site. The automated system quickly finds the right postcode for the address and house number you enter. Do you have the postcode and house number but not the street name? Then you can also use Royal Mail search function. This way, you will quickly have the correct information and you can give your postal items to the postman without fear of delay.

Other ways to find the right postcode

Apart from the Royal Mail postcode search, you can also use other websites. Some of these sites use maps where you can look up the street of the recipient. This function shows all postcodes of a street, so in order to find the correct postcode you will need to have the correct house number. Some of these sites go a step further and show not only the postcode of an address, but also the types of houses that are there and when they were built.
