Should I Generate a Different Bar Code in this scenario?

I have a product currently in production stand up pouches with no variations and will be sold as a pack of 100 (100 pouches in a clear bag). I already purchased a bar code for it and it is included on the back of the pouch design.

The clear bag is just an ordinary clear bag that is big enough to accommodate all 100 pouches and now, I am trying to get a sticker that will be on the clear bag.

My question now:

Do I need a different bar code for the clear bag that will house each pack of 100 pouches?

In the event that I choose to sell a pack of 50 using my discretion, would I need to get a new bar code for that?

PS: I checked the GS1 description for the generated bar code and it does not reference the number of pouches/per pack.
