Repair for a friend’s iPhone who lives outside the US
So I have a friend who lives in Venezuela he bought an iPhone 11 PRO Max with Apple Care. The screen got damaged. He can’t travel from Venezuela to the US. I live in the US. So the question is if he sends me his phone via International Courier so I can take it to an Apple Store for repair (either fix the screen or get a new one depending on the extent of the damage) would that be possible? If so, what would I need to bring to the store to get it fixed? I’d assume the Apple Care proof, the phone, the receipt if available and is an authorization is required? What else? Thank you
