A Postcard Collection App for Postcrossers
If you postcross, you know the joy of the mailbox — and the growing stack of cards on the shelf. Stamp Atlas is adding postcards: scan both sides, see every card on a map and keep the stamps they arrived with.
Sound familiar?
The shoebox keeps growing
Hundreds of cards, and finding the one from Finland with the lighthouse means emptying the lot.
Stamps you can’t name
You asked for nice stamps and got them — but what are they, and are any new to you?
Swaps in a notebook
Direct swaps, round robins and pen friends are tracked on scraps of paper, if at all.
How Stamp Atlas helps
Both sides, kept together
Photograph the picture side and the message side. The card, the handwriting and the stamps stay together as one record.
A map of your mailbox
See every country your cards have come from and gone to, and how far each one travelled to reach its new home.
Stamps you can actually look up
The stamps on your cards are identified and can join your stamp collection, so a postcard habit quietly becomes a stamp collection too.
Swaps beyond the platform
Log direct swaps, round robins and cards from pen friends alongside your official exchanges — and find new swap partners through public profiles and messages.

Questions
- Is Stamp Atlas part of Postcrossing?
- No. Stamp Atlas is an independent project and is not affiliated with or endorsed by Postcrossing. Keep sending and receiving cards there as usual — Stamp Atlas is a personal archive for the cards themselves.
- Can I record my Postcrossing postcard IDs?
- Yes. Each card has a field for its postcard ID (for example DE-1234567), so you can always match a card in your archive to its exchange.
- When will postcard features be available?
- Postcards are next on our roadmap after stamp cataloguing. Join the early-access list from this page and we’ll invite you as soon as postcard features are ready to try.
- Are my postcards and messages private?
- Yes. Your postcards — and especially the messages written on them — are private by default. Nothing is shared unless you choose to.
