Help How to get IMEI number from invoice?

[Android Question]

I have lost my Samsung Galaxy grand phone. I have bills, and box intact.

I want to know how to get IMEI number? In the invoice it is mentioned TIN number.
On the box only barcodes and 4 numbers below ending with *.

I wouldn't expect an invoice to have the IMEI. In my experience it is usually on a sticker on the box (just checked my phone box and it's there). But if it is on either it should be labelled "IMEI", so there shouldn't be any doubt about whether it's there or not. It's a 15 digit number (no letters) in case that helps.

It will almost always begin with the numbers 3 and 5 too.
