I recently found these vintage postage stamps, but noticed each was printed with "United Nations". I wasn't sure if these were regular postage stamps so I did a little digging.
Turns out the United Nations issues their own postage stamps. Did you guys know this?! The United Nations Postal Administration is the only organization in the world that isn't a country / territory that can issue postage stamps. The very first UN stamps in dollar denominations were issued in 1951.
There is one catch though, and it's a pretty big one. United Nations issued postage stamps cannot be used outside of UN offices. That means if you want to use these postage stamps to send mail, the mail must be sent from UN offices in either New York City, Geneva, or Vienna. Because of this constraint, UN postage stamps are more of a collector's item.
You might be lucky and find some vintage UN postage stamps at a local flea market or antique store, and you can buy current UN postage stamps either in person at a UN headquarters or online. It's even fun to just browse the catalog - so many different designs.
If you're able to visit the UN headquarters in New York you're in for a treat. You can have your photo taken and printed on personalized postage stamps. These are valid postage, but again have to be mailed directly from a UN headquarters. You can read about one visitor's experience here.
Pretty awesome, right? Did you know about UN postage already? Has anyone been to the stamp shop at the UN in New York? It will definitely be on my itinerary the next time I visit New York.
