Has it really been 20 years? The mind boggles at the number… that’s two whole decades spent thinking about this wild idea of connecting the world through postcards. 7,671 days of postcards, stamps, addresses, smiles, and stories. No one could have predicted this adventure would last this long… and yet, here we are. We’re so grateful for all these years, and especially grateful to the over 800,000 of you who joined us for the ride! THANK YOU! 💙

When I reflect on this milestone, I think a lot about creation versus maintenance. Putting something new in the world — whether it’s a project, a community, or even a child — is one thing. But caring for it and keeping it going year after year takes a very different kind of energy. There are countless hours behind the scenes (and the screens) filled with routine, repetition, and sometimes quite a bit of drudgery, just to keep things running smoothly.

But then, there are the stories. The unexpected postcards that bring someone to tears. The joy of discovering a new place or culture. The child learning geography from a map full of colorful cards. The grandma feeling less alone because someone, somewhere, thought of them. All these small and simple connections often make a very big difference in someone’s day, in their understanding of the world, or sometimes even in their sense of belonging. They’re the quiet proof that connection, even through something as analog as a postcard, still matters very much today — perhaps even more.

To everyone who has helped Postcrossing thrive, a very special thank you. Whether you’ve spread the word, hosted a meetup, helped out on the forum, sent feedback or helped support the project financially: you’ve helped keep this idea alive. ❤️ Your enthusiasm and generosity make all the difference.

Now it’s time for celebrations, and you guys have really come through! Our anniversary gallery is also brimming with nice photos of postcrossers and their 20 postcards, which is just a delight to see! If you haven’t posted your photo yet, we invite you to do so today. We’re all a community here, and seeing other people from all over the world who have this one thing in common with us feels really special.

There are an astonishing 179 meetups happening around the world marking the occasion, and so we hope many of you will have (or had) the chance to join to meet old friends or make new ones. 😍 In Germany, in the USA and in Poland (at the Warsaw Post Office 1's Philatelic Shop), special cancellation postmarks have been made for the occasion, so look out for those!

And if you didn’t get the chance to join a meetup, we invite you to join us in the Postcard Lounge today, for a relaxing moment of postcard writing! It’s a silent streaming room and an experiment in connection — a place where we sit down to write postcards together (but apart). Put some music on, grab your favorite drink and some postcards, and take a seat at our virtual table! ☺️

And last but not least, we also have exciting news for postcrossers in the Netherlands: PostNL is launching a celebratory stamp for this very special occasion! Hoera! 🎉

They should be available on PostNL’s shop from today, and we’re going to tell you more about this stamp in an upcoming interview with its designer… but for now, we leave you with a small introduction to the stamp:

"The Postcrossing stamp sheet, designed by Sandra Smulders, visualises the global exchange of postcards through bold geometric shapes and zigzagging lines. Inspired by the idea of connection and reciprocity, the design features triangles and rectangles symbolising people, postcards, and the world.

A red-white-blue colour scheme subtly forms the Dutch flag, while dynamic lines represent the movement of mail across borders. The central layout and repeating elements create balance and unity, capturing the spirit of Postcrossing—sharing, receiving, and connecting through mail."


So that’s it! Whether you’re joining a meetup, writing a card, or just quietly smiling at your mailbox, we hope you’ll find a little moment to celebrate this milestone in your own way. Eat some cake, raise a glass, dig into your postcard stash, or do a little happy dance — whatever feels most festive to you! And if you do something special to mark the occasion, we’d love to see it: feel free to share your celebration with us and the community on the forum or on social media, using the hashtag #postcrossing20.

Thanks for being part of this journey. Here’s to postcards, to people, and to the power of small things. And here’s to the next 20 years, come what may! 🎉

Oh, happy day — today is the day lucky postcard number 80 million has been received! Woohoo!

Whether you’ve sent just one postcard or many thousands of them, you’ve played a part in this achievement. Bravo, everyone! 👏 Also, we’re celebrating this milestone almost exactly 2 years after the last big milestone (70 million), so it looks like our trajectory is still very stable, with an average of 5 million postcards per year. Which is just brilliant!

Two Playmobil figures celebrate near a wooden mailbox and a yellow postal box filled with postcards. The text reads 80 million postcards! with Hurray! in smaller text near one figure.

80 million postcards is a lot of postcards though, and my mind is not quite able to visualize that many postcards… but this is where math comes in! Calculating the area of all these postcards, we know that they would be enough to carpet the Vatican with postcards two times and a half, or the area of the Forbidden City in Beijing over 1.5 times! Also, assuming each postcard weighs about 5 grams (0.17 ounces), all these postcards would weigh as much as 67 fully grown African elephants! 🐘

Now, we know what you’re really curious about: which postcard was the lucky 80 millionth, and who got the closest guess in our celebration contest? Without further ado…

Postcard number 80,000,000 was NL-5891077, sent by turtle_lover in the Netherlands on 23 December 2024 and registered on 07 January 2025 at 02:32:25 UTC by Flicki, in Germany!

And the sharpest guesser in our milestone contest? That honor goes to jennyfleur! You will receive a bonanza of papersisters prizes, including postcards, rolls of tape, stickers, a rubberstamp and more. But that’s not all! Runners-up dessie82, Emicho, Viiliaaa, Yunling, dhe and xxxxyyyyzzzz were just minutes off the mark and will also receive sets of lovely postcards and stickers to celebrate as well. Enjoy all these gifts, generously offered by papersisters!

No matter how many postcards you’ve sent or how long you’ve been a postcrosser, we hope you’ll take a moment to celebrate this milestone with us. Do a little happy dance, send an extra postcard, or share some Postcrossing joy with friends! This community thrives because of you — your love of connecting, sharing stories, and spreading a bit of kindness to mailboxes everywhere. 💌

And now, a brand new year unfolds ahead of us, with plenty of postcards waiting to be written. Let’s brighten mailboxes worldwide and come back to celebrate 90 million postcards in a couple of years!

If you’ve been following the numbers on the homepage, you know the 80,000,000 postcard will be registered soon… and if you’ve been around for awhile, you know what that means: it’s time to open the guessing game for this big Postcrossing milestone. Here is how it works:

Two Playmobil figures, a mail carrier and a seated person, are next to a wooden mailbox with letters. Text reads: 'Can you guess when postcard 80,000,000 will arrive?' and 'Place your best bet!'
Every member has a chance to submit a bet for the day and time on which they think the postcard number 80 million will be registered.
The bets need to be submitted on the contest page.

It should be easy: just choose a slot for the date and the minute you think postcard number 80,000,000 will be registered! You can have a look through Postcrossing’s statistics page if that helps… or maybe throw a dart at a calendar, or interpret some tea leaves — anything goes!

And naturally, we have some prizes as well, and this year it’s a veritable prize extravaganza! The 80 million guessing game is being sponsored by papersisters, who have very generously donated a bounty of stationery treasures for our winners:

Here are some rules we need to mention: each time slot can only be chosen by one single person, so the first postcrosser to pick that slot gets to keep it. You can change it at a later stage if you’d like, but only from the available time slots left. The bets will be automatically closed when there are 1000 postcards left to postcard 80,000,000. Check the contest page for more details.

Keep sending postcards and refining your guesses, and keep an eye on the counter on the frontpage of the website to know how many postcards still need to be registered. Good luck, everyone!

What a way to start the year in style, with 70 million postcards in the hands of postcrossers all around the world! 🎉🎉🎉

It’s been almost two years since we last celebrated one of these milestones (10 million postcards ago), so if you do the math, this means we’re averaging about five million postcards per year here in Postcrossing… which is pretty impressive! Well done, everyone! Whether you’ve sent one single postcard or 10 thousand of them, you’ve contributed to this milestone too!

Can you guess how far we’d get if we made a little path with these 70 million postcards, all put together side by side? It’s a line that stretches aaaaaaall the way from London to Sydney down under! Or from New York to Melbourne!

I guess what you really want to know is which postcard was the lucky one, and who guessed the correct time at which postcard 70 million was registered. So, without further ado…

Postcard number 70,000,000 (US-9001590) was sent by jmorris in the USA on 26 December 2022, and registered on 04 January 2023 23:36 (UTC) by BowieGirl, also in the USA!

The postcrosser with the best aim on our guessing game was henna168, whose bet was spot on! Keep an eye on your mailbox for your new box of 100 postcards, which will be on its way soon!

The other lucky postcrossers who came super close to the correct second were _Vika_, serenji14, Larch, LeviEng, sharkee and Mirunka! You will each receive a set of nice postcards as well. We hope you like it!

No matter where you are, or how many postcards you’ve sent, we hope you take a moment today to do a little dance and celebrate this nice milestone! This community is made of so many different people, and we’re thankful for each and every one of you. Your passion for happy mail and for connecting the world is the reason this project exists!

Ok, enough sappiness… let’s go brighten some mailboxes, and see if we can make it to 80,000,000 postcards before January 2025! 💪

It’s almost time! The 70,000,000 postcard might already be on its way to the lucky recipient, so now is the perfect moment to open the guessing game for this big Postcrossing milestone. Here is how it works:

Two small toy mail carriers stand in front of stacks of postcard books.
Every member has a chance to submit a bet for the day and time on which they think the postcard number 70 million will be registered.
The bets need to be submitted on the contest page.

Pretty straightforward, right? Just choose a slot for the date and the minute you think lucky postcard number 70,000,000 will be registered according to your gut feelings. Feel free to have a look through Postcrossing’s statistics page if that helps, or maybe ask your local fortune-teller for a hint!

And as has become tradition in these events, we have some nice prizes too! The postcrosser whose bet is the closest to the exact minute when postcard number 70 million is registered will win a box set of 100 postcards, and the 6 next best guesses (before or after the registering time) will receive a pack of 20–30 postcards each. 🎉 Hurray!

Here are some ground rules: each time slot can only be chosen by one single person, so the first person to pick that slot gets to keep it. You can change it at a later stage if you’d like, but only from the available time slots left. The bets will be automatically closed when there are 1000 postcards left to postcard 70,000,000. Check the contest page for more details.

Good luck, everyone! Keep sending postcards and refining your guesses, and keep an eye on the counter on the frontpage of the website, to know how many postcards still need to be registered… any day now!
