Where can I post franked mail?

For the full guide, see our main article: Can you put franked mail in a post box?

You can’t drop loose franked mail into a standard red post box – it can be delayed. The three correct options are: a Royal Mail-approved meter posting envelope (which can go in a post box), a Business Posting Box, or by handing it in at a Post Office, Enquiry Office or Mail Centre.

1. Meter posting envelopes

If you want to use a standard post box, place your franked items inside a Royal Mail-approved meter posting envelope first. You can fit up to 30 franked items in one, and the envelope must show your serial / meter number.

2. Business Posting Box

You can place franked mail directly into a Business Posting Box. Royal Mail can tell you where your nearest one is.

3. Post Office, Enquiry Office or Mail Centre

You can also hand your franked mail in at your local Post Office, Royal Mail Enquiry Office or Mail Centre.
