Getting receipt
I purchased an iPhone for my wife but was never emailed the receipt. How do I get a copy?
iPhone SE (3rd generation)
If you bought that iPhone at Apple Online Shop, contact Apple directly using this link:--> Contact Apple for support and service.
In all other circumstances (Apple phisycal Stores, Authorized Resellers, who have their own accounting system) contact the seller and ask for a copy of that document.
