Do Stamps Expire? In short - NO, they do not ever expire as long as they can be validated as legitimate postage. Damaged or otherwise unrecognizable stamps will likely be rejected. But you have to be careful, as rate changes are happening and changing how postage itself is calculated.
Even mail that seems to be properly wrapped, addressed, with the correct postage may be brought right back to you. The post office reserves the right to refuse to ship what it considers non-mailable or improperly packaged items. This is a frustrating experience so here some tips on how to avoid that.
Why is Forever Crossed Out on Forever Stamps? Can I still use a forever stamp? How much does it cost for a Forever stamp? Everything about Forever Stamps is Here. We all are tired of Postage Rate increases and are quite unhappy with how the price creeps up over time. However, the Post Office came up with a solution to make our lives easier and less-math filled: Forever Stamps.
Chances are if you have been shipping packages for more than a few years, you might not even be aware of the changes to the pricing system for a parcel. In 1997, shape-based pricing was introduced. It used to be that all parcel shipping prices were assessed by a weight-based calculation system. It used to be that sending an oddly shaped parcel like a guitar case would cost the same amount as a small rectangular parcel carrying the same amount of weight. Since the concept of Dimensional weight has been adopted worldwide, you could pay a lot more for that area. The cost of shipping smaller lightweight parcels has increased dramatically as well.
The day-to-day concern with accepting parcels is that they must be packaged well enough to protect their contents and strong enough to prevent the package from breaking and causing injury to employees or damage to other mail. Most people send normal items: documents, clothing, toys, etc. There are times when questions might arise about what can be sent and how.
