To mail a 12 oz package using Forever stamps, you would typically need to use the postage rate for the package weight class. As of my last knowledge update, a 12 oz package falls under First-Class Package Service, which costs about $5.70. Since each Forever stamp is worth the current First-Class Mail letter rate (which is $0.66 as of 2023), you would need approximately 9 Forever stamps to cover the postage for a 12 oz package. Always check the latest postage rates for the most accurate calculation.
