How does the barcode system works?

Like how is there no overlap of barcodes at all? There’s are millions if not, billions of items around the world that have unique barcodes. Are they differentiated per country or something?

There is a company that sells domains, you can buy a single number for a few cents, or the last four digits with the rest fixed,
you can have it point to a company or country and decide the last numbers in house,

Although there are super markets that made their own system and have to cover everything in stickers for it to be compatible
