Posting Franked Mail – How to find your nearest post box
You can drop your franked mail off at your local post office, or alternatively you can drop it in to one of Royal Mail’s Business Posting Boxes, known as a franked mail post box. Franked mail should not be posted in an ordinary post box due to Royal Mail’s sorting system and doing so will likely cause delays to the delivery of your mail.
Unfortunately, Royal Mail do not provide an online post box locator, so to find your nearest franked mail post box contact the Royal Mail Business Advice line on 0845 6050767
If you want to drop your mail off at your local Post Office, find your nearest branch and its opening hours using Royal Mail’s branch finder
Most Post Office branches have a separate business window for you to quickly drop off your franked mail pouches for delivery.
Royal Mail also provide a pick up service where your franked mail can be picked up from your office. There is an additional charge for this service, unless your business spends more than £15,000 a year.
