If it's not with your order details , eBay messages , emails or Spam, contact Customer Services for this essential code, as you know you have 7 days to pick up your item from when you were notified it's in store.
I strongly recommend contacting CS 8 a.m. on a weekday when the lines open for ' live agents' as then, there's more chance of Dublin answering.
This is the easiest and quickest way to contact eBay Customer Services, for a Call Back option.

Lines open 8 a.m. - 10 p.m. on weekdays
9 a.m. - 6 p.m. on weekends.
Automated agents will be available on chat outside of the above hours.
It's not easy to get through to CS, you just have to have perseverance! Instead of a quick option, 'Contact Us' which put you direct to a CS agent, you have to scroll past ' How Can We Help you today, to the very bottom and click on the Contact Us below Need More Help?
That takes you to an annoying AI bot but if you persevere keep asking questions it cannot answer and Insist on an agent, they do finally put you through and say .... waiting time ** minutes!
