How to know if my iPhone is original

Hello eyalo,

Welcome to Apple Support Communities. It sounds like you would like to make sure that your iPhone is a genuine Apple product. Right?

The best way to make sure that you receive a genuine Apple product is to purchase directly from an Apple Authorized Reseller. You can find those from Find Locations - Apple. You may need to change the country location from that page to see local results. From that same link, you can also find service locations who can inspect your iPhone if you have reason to believe it may not be genuine.

Take care.
