Many sellers are calling the support line this week as they cannot find the MPN numbers confusing!
So firstly MPN is the abbreviation for Manufacturer Part Number
Typically the MPN is to be found on the part or the packaging, or failing this you should be able to find it on the manufacturer’s web site.

So if I was looking to add an MPN for a candle product called
Bridgewater Candle Scented Wax Bar 2.6 Oz. – Sweet Grace
Example:
Firstly I would do the following search in Google “Bridgewater Candle Scented Wax Bar MPN“
Next I will check from the search results those MPN numbers that match as these customers will have done it correctly.
The last Step if it was required was finding the information on the website
This is an arduous task. I would be more inclined to ask your suppliers for this information and then bulk upload this information in a tool like Ad-Lister
