I was wondering, is it possible to change or delete business info from a paypal account?

Its a US verified Business Account

Give PayPal support a call and they will update your business info immediately.

Sorry for the drag, but i found out how to change a business name, here is the procedure:

Go to paypal
Click Help
Type "how to change business name"
Click the first link there
Use the "secure form"
Poof
Business name changed :)
