Linking your PayPal account to your eBay account
If you're already PayPal Verified, you can link your PayPal account to your eBay account to confirm your identity. Identity verification keeps eBay a safe place to buy and sell.
You can also link your PayPal and eBay accounts to make buying on eBay even easier. When you have linked accounts, and your seller accepts PayPal, you can use eBay's Checkout process to quickly pay for your item and have it shipped to your preferred address – all with a few clicks of your mouse.
To link your eBay account to your PayPal account:
Click My eBay at the top of most eBay pages.
Under the Account section, click the PayPal Account link.
Click the Link My PayPal Account button. You'll be asked to log in to PayPal to finish linking your accounts.
