If ebay have advised  you that you will be paid into your bank account that appears to show that you have gone through the managed payments process with them.  Ebay only quote the last 4 digits of your bank account for your security. If you go to your account settings you will still only see those same 4 digits. When you supplied your account details to ebay they would have verified the account at the time.

It can take up to 30 days for payments to appear in an account when a seller hasn't sold for a while. I suggest you check your bank account balance. Don't know if your bank offers the option to send an email advising of any deposits, but if they do, it is a good idea to authorise this feature to save having to keep logging into your bank to check the balance. When my bank advises me of a deposit their email tells me the amount deposited into my account ending in the last 4 digits of my account number.  Employing the same precaution as ebay did in their email to you.
