Does product code need to be unique?

magento 1.9.3.7

Do product code need to be unique on magento? I assume they need or else I don't see any purpose with it. Just asking anyway as I'm converting a old shop over to magento and there product code is not unique... If product code need to be unique I need to add some logic that make them unique while I import them...

Yes the product code, the "SKU" in Magento must be unique.
