Join PayPal if you have not done so and fill in the required application. Choose what type of account you will need, whether it's a Personal, Premier or Business account.
Log into your PayPal account, under the "My account" tab, then click profile. Click on the "Add or edit bank account" link until another screen pops up, asking you whether or not this is a checking account or savings account.
Choose "Checking account" and enter your bank routing number. Enter your bank checking account number, then select continue.
PayPal will make two small deposits into your account. Check your bank statement after three days and find those two deposit amounts.
Log into your PayPal account, then select "Bank accounts" and confirm those deposits. You just opened a checking account using PayPal.
