Do you remember last year, when we mentioned there would be a special souvenir on Geocaching for official events taking place around World Postcard Day? Well, it was a huge success: 19,260 geocachers attended at least one event during that week, and the number of events nearly doubled compared to 2023. We were blown away by these numbers, and are thrilled that Geocaching is continuing this collaboration in 2025! 🎉
So here’s the scoop: from September 28 to October 4, 2025, if you attend any official Geocaching event and log your attendance, you’ll receive a special World Postcard Day souvenir on your Geocaching account. The dates line up perfectly this year, with October 1 (World Postcard Day) falling right in the middle of the week.
For those who might not be familiar with it, Geocaching is a global treasure-hunting game played outdoors with the help of a GPS or smartphone. Players search for hidden containers (called “caches”) all around the world, sign their logbooks, and then share their adventures online. Much like Postcrossing, the community meetups on Geocaching are all about connection around a common hobby.
And what better way to celebrate that than by combining the two hobbies? Geocaching events are a great opportunity to meet fellow geocachers, exchange stories, and maybe even write a postcard or two. Some groups even organized joint Postcrossing + Geocaching meetups last year, and we’d love to see more of those in 2025!
If you can’t find an event nearby, you can always organize one yourself. Just remember that events need to be submitted at least two weeks in advance and meet all of Geocaching’s guidelines.
For inspiration, check out Geocaching’s wrap-up post from last year, filled with photos (and postcards!) from events all over the world.
Whether you’re out hunting for caches or sending a postcard across the globe, mark your calendars for the last week of September. Grab your GPS, pack a few postcards, and join the fun!

This sounds like fun
What denotes an "official" event on this day. It is any event?? Wish there was such a thing as a virtual event as I am in Northern Canada and there are never any events here.
If you are in Tampa, Florida, USA there is a Post Card Day / Geocache event in Seminole on Oct 1.

I love geocaching! I have sent some geocaching "bugs" with my postcrossing cards, and have fun watching them travel from country to country. It's fun
I have never tried geocaching, but it sounds like a fun adventure!
As a geocacher and postcrosser, I'm really looking forward to these days! :)
I'm sure there's a suitable event in my region (which I'll look for right away).
Ich bin Postcrosser und schon seit Jahren Geocacher. Habe direkt nach einem GC Event in dem Zeitraum gesucht und auch gefunden. Werde daran teilnehmen und freue mich riesig....
I'm a postcrosser and have been a geocacher for years. I immediately looked for a geocaching event during that time and found one. I'm going to participate and I'm really looking forward to it...
Can't wait for another 2 in 1 day! My favorite hobbies getting together, a dream come true! :D
I have quick Geocaching and Postcrossing events booked in Seattle, at Geocaching HQ at lunch hour (sorry, it was the best I could do). The idea is a quick withdraw of postcards and sign a few, to writte them and deliver at the airport cause I'm coming back to Europe that afternoon.
Drop by for a quick hello! :)

In Switzerland it's pretty easy to attend a geocaching event, as several will pop up. Last year I joined an event where postcards were offered as give-away, and I was happy to grab a nice one. Let's wait which event I will join this year, I definately will in order to get the souvenir by geocaching.
Geocaching + postcrossing! Awesome!
Wow, this sounds like so FUN-FUN-SuperFUN!
I will try to find an event in Romania!
Nice idea!

It looks good! Malsehen!
Can't wait to attend this event!
unfortunately Geocaching is not common in Indonesia...
So awesome and fun!
A wonderful combination of passions. As I practice both, I'm going to create a geocaching event in Toulouse to get this souvenir.
It sounds wonderful but I keep it only with postcrossing.
Interesting! I'll give this a try.
Seit 14 Jahren mache ich Geocaching und seit 4 Jahren Postcrossing.
Wie letztes Jahr veranstalte ich am WPD ein Geocaching-Event in Tirschenreuth (Bayern), zu dem auch alle Postcrosser eingeladen sind.

I've been geocaching for 14 years and Postcrossing for four.
Like last year, I'm hosting a geocaching event at the WPD in Tirschenreuth (Bavaria), to which all Postcrossers are invited.
I've never done geocaching and I'm curious about it. But! I have participated in sending postcards on World Postcard Day. Can't wait!
How do you log an event on Postcrossing, after attending a Geocaching event?

Eine Woche wo meine beiden Hobbys zusammen treffen. Natürlich geht es zu einem Event am Wochenende! Und Postkarten kann man zum Glück von überall aus verschicken!
