IS there a method to retrieve serial numbers from old iphones through Apple?

Hello Jgg181.

Welcome to Apple Support Communities. We understand that you want to know if you can retrieve the serial numbers to your previous iPhone. We’re happy to help.

There’s no specific method to retrieve those serial numbers. If you have the receipt or the box, you can get the serial number from there. We also recommend checking your email for any receipts. You can go to the place of purchase to see if they are able to print past receipts. If your purchase was made at an Apple Store, please go here to locate the Apple Store where you made your purchase and contact them for the receipt: Apple Store - Find a Store - Apple

Let us know if you have further questions.

Take care.

Hello Jgg181.

We’re glad that you were able to get the serial numbers you needed.

Take care.
