If there is no return address on a domestic item which could not be delivered, the item will be sent to the National Returned Letter Centre
The National Returned Letter Centre will open the item and return it if the name and address of the sender is inside, as long as it is not a newspaper, magazine or advertising.
If there is no return address inside the item, and the contents appear to be of sentimental, legal or financial value, we will hold it at the National Returned Letter Centre for three calendar months, after which time we will dispose of it.
Items from abroad are returned to postal services in the country of origin.
