Is it possible to get the barcode database of an online store?

Question

Database

There is an online store, for example, www.utkonos.ru
In free form they have: product name/description/picture/article
The question is, is it possible to somehow get, in addition to this information, barcodes that will match a specific item number? Or is this only possible if you work as a programmer in their store?
They have a very good product description, pictures. If we simply download their database, then we will not be able to match it with our products by name (this entails a lot of errors), the only thing that matches between us and them is the barcodes of the product. How can you do it? They don't give it freely.

Answer 1

If they do not have barcodes published on the page or it is impossible to understand from the URL of a particular product that this is a barcode, then there is no way without someone who has access to the site from the inside. Or try to negotiate with them for good.
Or find on some other site where they get the goods from (from their suppliers).
