A business I am dealing with has asked me (online) to send them some information by freepost. Do I just write 'Freepost' before the address they gave me or is there more to it than that?
Freepost™ Standard Handwritten
You provide the Freepost address and licence number and the customer writes it on their own envelope or postcard. You can also choose to provide the customer with a pre-printed envelope. The finalised address format must be approved by Royal Mail.
