Are you the buyer? Is this to pick up a click and collect item from a designated store?
If the code is not with your order details or eBay messages, emails, then contact eBay Customer Services they will provide that essential code for you.
Once you are notified your item is in store, you have 7 days to collect your item.
This is the easiest and quicket way to contact eBay Customer Services, for a Call Back option.

Lines open between 8 a.m. to 10 p.m. on weekdays.
9 a.m. to 6 p.m. on weekends.
I recommend contacting CS very first thing in the morning, when the lines first open, as there's more chance of Dublin answering.
