In this digital age, snail mail seems like a thing of the past but for those who still receive correspondence via postal service it's important to know how to format a uk address on an envelope correctly. Correct formatting makes it easy for post office staff and machines to read, transport and deliver your letter or package to the right person at the right address. It also helps avoid expensive and time-consuming reshipping of items to the wrong recipient.
The first line of an envelope should include the recipient's name, followed by their house number and street or road name, then the town or village (although this is often skipped) and the full post code in capital letters. It's also a good idea to add the county (although again this is often skipped) and the country in which they live, especially if they're a serving member of HM forces.
Lastly, if it is appropriate and relevant, you can write the department within the company if the recipient works there. However, it is never mandatory and may be left off if it is inconvenient for the recipient. If the recipient has a professional distinction or title such as 'Mr' or 'Ms', you should also include this on the envelope, though it is not always necessary.
