I was almost dizzy trying to figure the postal system in Italy! It seems the trick is to buy your postcard, your postage stamp and know which mailbox you are dropping it all into before you leave the vendor.

Poste Italiane- stamps are not available in souvenir shops, and not always available at tabaccherias (local smoke shops). Drop this stamped card only in a red mailbox!

Globe Postal Service (GPS) – more expensive than one above, stamps are available at souvenir shops and some smoke shops, but you MUST drop this stamped card in their mailbox! QR code on the stamp so recipient can confirm receipt.

Friendpost- never found this option; supposedly available.

I used TouchNote app, chose my photo for the card and wrote my message. My order was shipped within 2 days and 6 days delivered from Italy to Arizona, USA. I saw the delivered card. It is sturdy and good quality. Message and photo all clear. Yes, I paid for this service, but it was worth it! My photo, my message, no finding the right stamp and mailbox, and so easy! I’ll use TouchNote for other personal postcard needs… and I think more products are available with this TouchNote app! Check it out! It may be helpful for you when on the road traveling!
