Which Stamp Is Best for Your Mail: Global or Regular Forever?
The best stamps depend on where you want to send the package or mail. If you want to send an international package, then the Global Forever Stamp is a superior choice. If you are mailing within the US, then domestic Forever stamps take the edge.
Common Mistakes When Choosing Between Global and Forever Stamps
These are some common silly mistakes many people make while choosing between Global and Forever Stamps:
- Using Forever stamps for international mail without calculating: Some people may use two stamps and call it a day. However, doing the math, you need exactly 3 Forever stamps to send an international 1-ounce letter.
- Buying counterfeit stamps because of the discount: If you find stamps with an extraordinary discount, it would be best to pass that offer because the chances of them being counterfeit are really high.
- Not recognizing non-machinable mail: Make sure your mail is evenly thick and doesn’t meet USPS’s required dimensions: a letter 5-11.5 inches long, 3.5-61/8 inches wide, 0.007-0.016 inches thick, with an aspect ratio of 1.3-2.5, according to USPS.
- Letters not meeting these criteria are considered non-machinable, and you have to pay extra postage, because their automated sorting system can’t sort them.
How Postal Rates Affect Global Forever and Forever Stamps
Postal rates directly affect the current price of Forever stamps; however, they don’t affect their usability. Since the value of Forever stamps remains the same, they can be used to send a 1-oz letter. However, the value of other stamps depends on postal rates.
