Items purchased as an eBay Guest:
Look for the confirmation email from eBay. You will be able to see your order details (i.e., purchased items, shipping status, tracking numbers) by following the link in the confirmation email. There will also be information about returning an item or reporting that you didn’t receive an item.
Once you find your eBay guest order confirmation email (the subject line starts with “Guest Order”) select View order details in the email. Enter your email address and access code to sign in as a guest user. You can choose to contact the seller, leave feedback, or return the item.
If you already have your Access Code, click on the link below. You should see the eBay sign in page. Click on the arrow next to Guest User and enter your email address and access code (see screenshot below the link):
