Can you reuse product identifiers for in app purchase on iOS?

Question

When you pick a product identifier in iTunes Connect does it have to be unique throughout the app store, or just within your app? And if you delete a product with a given product identifier, can you then reuse it for a different product? I've been doing some testing in iTunes Connect but I don't want to sabotage the most logical ProductID's during my testing.

Answer 1

I've discovered, once you delete a product with a given product identifier, iTunes Connect does not let you reuse that ID again. However, I've found a workaround. The product identifiers are case-sensitive, so if you just change your capitalization when you reuse the product id, iTunes Connect won't stop you. (However, as il Malvagio Dottor Prosciutto states, that could be risky).

Also, with brief testing, it doesn't appear that your product identifiers have to be unique throughout the store. I tried some pretty common words that I thought others might have used for product ID's and they all worked.

Note that the products I did my testing on were various durations of a recurring subscription in the app store. I don't know if the rules differ for other types of products.
