When you join DX Document Exchange, you’ll be given your own unique DX number and a secure mailbox at your local Exchange. Alternatively, you may wish to speak to us about hosting your own Exchange.

Sending business mail

You can start sending your mail through Document Exchange right away, following these simple steps:

1. Find the DX address of the company you want to send your item(s) to. You can look it up using the DX Directory Online, or through a number of other DX Directory Services. Our system uses a unique 3-line address format instead of a postcode address:
   
   
   • Company name
   • DX number
   • Exchange name

    

2. Prepare your mail, adding the recipient’s name and 3-line DX address. There is no need to weigh or frank your Document Exchange mail. Please ensure you put your own DX address details in the top left hand corner of each item.

    

3. Take your mail to your local Exchange, and post it into the Outgoing Mail Box before 5pm. If you want to send mail to DX Members within your own Exchange, you can simply deliver mail directly to their DX postboxes at any time.
   

Receiving mail

Our delivery team will post all your incoming DX mail into your private, lockable mailbox at your local Exchange before 9am.
