How to assign unique ID for each item under product?

[hfixexpert]

I sell phones and need a way to track IMEI (unique phone ID thats different for each phone). 

For example, my product is Iphone 12 Pro.  Variants could be color and storage.  I could have several units of each varying by type.  However, each phone has a unique IMEI that i need to input into the inventory system to keep track of each phone.

So for example if I have (10 quantity) Iphone 12Pro 128Gb in blue, then a unique identifier (IMEI) has to be assigned to each phone for accurate tracking.  I cannot use SKU or create a new product for each IMEI as that would lead to inaccurate inventory.

Is there a way to add an additional detail to assign a unique (identifier) to each phone and still manage proper inventory?

I suggest using an app like Bold product options to manage hidden variants and provide for customization on your product page.  You can then set your individual variants to be inventoried for proper inventory management.
