i think the answer to that question is absolutly obvious. Because i have an acount. though i never used it i have an acount.
with my email adress and password, i didnt expect them not to use authentication, but i asked WHERE do i find my ID?
THere is your email address and password to log in. Once you are logged in, you will find your profile. Go there. there is no id as in a number, or whatever.
Your email address is your ID, if you've forgotten which email address you used to sign up for the account, you can still go to the PayPal login page and then follow the link for "Forgot your email address"
yes, most of these answers are answered in paypal site, also you can send mails to their customer support. Even though it is little complicated, they will respond to your query in couple of days.
