3. Can I distribute redemption codes to employees who are not located in my country?
No. Apps can only be distributed to employees with Apple IDs located in the same country where the apps were purchased. To distribute redemption codes in other countries, you must enroll your business in the Volume Purchase Program for every eligible country in which you wish to purchase and distribute apps.
