Are Product and variant id's unique

in Development
Currently I'm developing an application using the eCom API which stores all variant and product id's in one key value dictionary. Can I assume there will never be a duplicate id if I store both variant and product id in one dictionary? In other words are variant and product id's always unique even combined?
Thank you for your time.

Hi @dmizrahi,
Product_ID's and Variant_ID's are indeed unique, even combined.
