Hello, @Crafter3. Thanks for taking the time to add your question here on the PayPal Community Forum. If you're adding a bank account or card to your PayPal account, you need only add your bank or card information. There's no PayPal Customer ID to add. When you have a bank account or card linked to your PayPal account, adding money is done via the Transfer option after clicking on Balance. Please check out https://www.paypal.com/uk/smarthelp/article/how-do-i-add-money-to-my-paypal-balance-faq1348 for more information. I hope this is helpful.
