What do the numbers behind the name of the notebook mean?

I have a question for technical experts. I'm currently looking for a convertible notebook for my studies. (Tips are welcome. And I noticed that the last few numbers are different for many types of laptops at different retailers. For example, digitec sells the product: HP Envy x360 13-ar0205ng and MediaMarkt the HP ENVY x360 13-ar0604nz. (One of my favorites at the moment.) Do these different numbers have to do with a different series or is it just that the retailers can identify your product?

Ka, the Microsoft Surface models are great.

(If not cheap)

What would your budget be?

I would be willing to spend about 700 to 1000 francs.

Good question where the difference is.
Think there's no difference for the consumer, maybe a device was produced a few months later with minimal changes e.g. Another revision number of a hardware module (possibly WLAN) … Can only guess.
