In general... don't give out information that's not needed... and give out fake information when not needed, but required by stupid webforms. So yeah, I'll give actual information to government, insurance, bank etc, but mostly bullshit (even name, DoB, etc) to (web)shops. Besides the address a shop doesn't need anything from me, so they usually get a throwaway e-mail, no phone-number or 0123456789 and only a postal-address if buying physical goods for delivery. For mail-addresses where I need them later, always just customize them (like with gmail using youraccount+webshopname@gmail.com or with self-hosted using postfix's + or - address seperator).
