1st class mail 可以投到郵筒 英國

😊

In the UK, Royal Mail's 1st Class mail can be posted in a postbox, but there are some conditions to keep in mind:

  1. Postbox size and shape: The postbox must be a standard Royal Mail postbox, and the item must fit through the slot. If the item is too large or irregularly shaped, you may need to take it to a post office or a larger postbox.
  2. Weight and size limits: 1st Class mail has a maximum weight limit of 100g (3.5 oz) and a maximum size of 240mm x 165mm x 15mm (9.4 in x 6.5 in x 0.6 in).
  3. Postage cost: Make sure you have the correct postage. You can use a postage stamp or a postage label. If you're unsure, you can check the Royal Mail website or ask at a post office.
  4. Postbox location: Not all postboxes are 1st Class mail-enabled. Look for a postbox with a 1st Class mail symbol (a red circle with a white "1st Class" logo) or a postbox with a "1st Class" label.

If you're unsure about posting your item in a postbox, you can always take it to a post office or a larger postbox. The staff will be happy to help you with your mail. 📨
