Numbers and letters in buyers addresses

[2gorgeousgirls8182]

I have noticed that there are a set of letters beginning "ebay4 " etc next to buyers addresses in the order details. Does anyone know what these are for and do I have to include them in the postage address when I send the items? Thanks.
