One Forever stamp can be placed on an envelope weighing nor more than one ounce. For each additional ounce you would need an additional $0.21 of postage. You technically can just put multiple Forever stamps on an envelope, but you would most likely be over paying for postage if for example your envelope only weighed two ounces.
A Forever Stamp is non-denominational first class stamp that guarantees its usage no matter what the current price of postage is. For example if you bought one 2013 for $0.41, you can still use it in 2017 despite the fact they now cost $0.49. If you only are using one to mail a letter, the total weight of the letter, envelope, and stamp, cannot exceed one ounce. If you want an idea of how much one ounce is, its equivalent to a pair of standard dice.
The three most popular forever stamp products are the American flag, the purple heart, and Love (a must have for wedding invites). You can find other pictures on them such as fireworks, flowers, the Statue of Liberty, the Liberty Bell, and some seasonal choices like a snowflake. These stamps are of course available at your local post office, but there are other retail locations that sell Forever stamps.
Forever Stamps at Costco
One of the most popular places to buy them besides USPS is in the business service center of a Costco. They are sold, by the book so you can get several of them at once. They also sell envelopes and other mailing supplies that you can load up on, while you are picking up your stamps.
Do Greeting Cars Weighing More Than Ounce Need More Than One Forever Stamp?
Yes. The weight cannot be more than ounce. If it is you are subject to pay additional postage. My best advice is to have it weighed at the postal service so that you don’t overpay for postage. For some throwing on two stamps and eating the couple extra cents you will pay is probably no big deal. For others you’ll want to all pay for the weight you are sending.
What is the Maximum Size of an Envelope for First Class Mail?
The max size is 11 ½ inches x 6 1/8 inches x 1/4 inch thick. Something this size would be considered a standard envelope. If you that go over these dimensions or it weighs more than 3.5 ounces, it gets a rate as a flat (costs a little more).
Do First Class Flats Have to Be Flexible?
Yes. Large envelopes need to have some flexibility to them and cannot be more than 3/4 of an inch thick. This is because it needs to run through a AFSM Flat sorter machine, which only allows for a certain thickness. If your large envelope exceeds 15 inches x 12 inches x 3/4 inch thick it is considered a parcel and priced accordingly (cost a little more).
How Much Weight Can a Package Be For a Book of Forever Stamps
There are 20 stamps in a book. So technically you could mail a package up to 20 ounces with an entire book of stamps. If you have the ability to weigh the package on your own, then that is not a bad option. I caution you on guessing, because if you mail it with insufficient postage, it will be returned back to you.
Can You Get Forever Stamps at a Discount
Finding stamps on sale is difficult, but not impossible. Normally grocery stores will offer occasional discounts on them. The savings isn’t huge, but if you are buying multiple books it can add up. The normal discount you can find is about 4% savings.
Can a Forever Stamp Be Used on International Mail?
International mail is subject to different rates. a ounce letter being sent internationally costs $1.15. Your normal Forever stamp does not cover enough postage for the shipping. USPS however does offer the Global Forever stamp. These cost $1.15 a piece and work the same way the regular ones do. If the price goes up two years from now, the Global stamp you purchased is still accepted as long as your envelope doesn’t exceed one ounce.
