If you use a US iTunes account, and have a “fake” address, you may be getting an error that says you have an “Invalid Address” when trying to purchase or update apps. It looks like Apple has implemented address validation on your iTunes account, and I have had quite a few people contact me today about this issue.
The reason this is happening, is because your address is not in fact a valid physical address. You will need to update your details either through iTunes (iTunes Link) or using the App store app on your iPhone/iPad.
If you are getting an error using a Valid address, try changing “Street” or “Drive” to “St” or “Dr” or vice versa.
Make sure you your new address’s telephone number matches your new address as well.
Good luck :)
