Do you need to put air mail on letter uk

In the United Kingdom, you don't need to put "Air Mail" on a letter to indicate that it's being sent by air. The Royal Mail, the UK's postal service, uses a system of barcodes and tracking numbers to identify and prioritize mail, regardless of whether it's being sent by air or surface mail.

However, there are a few situations where you might want to use an "Air Mail" sticker or label:

  1. International mail: If you're sending a letter to a country outside the UK, you may want to use an "Air Mail" sticker or label to indicate that it's being sent by air. This can help ensure that your letter is prioritized and delivered more quickly.
  2. Priority delivery: If you need to send a letter quickly and want to ensure it's delivered as soon as possible, you can use a Royal Mail "Special Delivery" service, which includes an "Air Mail" label.
  3. Customs forms: If you're sending a letter that contains goods or merchandise, you may need to complete a customs form. In this case, you may need to use an "Air Mail" label to indicate that the item is being sent by air.

In general, if you're sending a standard letter within the UK, you don't need to use an "Air Mail" sticker or label. The Royal Mail will automatically prioritize and deliver your letter using the most efficient method available.
