Postcrossing: Delivering surprises, one postcard at a time

On February 17, I wrote a blog post on how Denmark and India have adapted their postal services differently to the challenges of the modern digital age. The idea for that post came about when I was at the General Post Office in Bengaluru to send a few postcards.

I mentioned then, "Why I was sending postcards is a story for another blog post!" Well, here it is.

But before that, a short backstory.

POSTCROSSING

Several years ago, given my interest in listening to the radio, I was discussing QSL cards with a friend, Shiva. 

A QSL card is a written acknowledgement of radio communication between amateur radio operators or from radio broadcast stations. These cards are the same size and material as standard postcards and are most often sent through the mail.

He then told me about something called ‘Postcrossing’, which I had never heard of. He explained how it works. I was keen on trying it out, but work commitments left me with little time for it. Finally, a couple of months ago, on January 15, I signed up.

It is a simple hobby: you send a postcard to someone, somewhere in the world, and sooner or later, another postcard arrives for you from a completely different corner of the planet.

On February 16, I went to the General Post Office to send a few Postcrossing cards. So far, I have sent six postcards, and I received my first one the day before yesterday (22 March) from Bavaria, Germany.

(Sending my first Postcrossing postcard was an ordeal in itself — but that’s for another blog post!)

The more cards you send, the more you receive. But at the heart of it all is the serendipity and the joy of discovery.

HISTORY AND EVOLUTION

Postcrossing was created in 2005 by Portuguese software developer Paulo Magalhães. He loved the excitement of receiving real mail and wanted to recreate that sense of surprise for others.

The project officially launched on 14 July 2005. What began as a personal experiment soon spread rapidly through word of mouth and media attention. By April 2008, the community celebrated its first million exchanged postcards. By early 2026, more than 85 million postcards had been registered on the platform.

HOW POSTCROSSING WORKS

1. Create an account: Anyone can sign up for free on the Postcrossing website and create a personal profile.

2. Request an address: The system generates a random recipient from another country along with their postal address and a unique Postcard ID (for example: US-12345). You then send a postcard to this person.

3. Send the postcard: Write a short message, include the Postcard ID, attach stamps, and post it just as you would any other letter.

4. Receive one in return: Once the recipient receives your card, they register the ID on the website. You then become eligible to receive a postcard from a random Postcrossing member. In essence, every postcard you send eventually results in one arriving for you.

When you first sign up, you are eligible to send up to five postcards. As more people receive your cards, your limit increases, allowing you to send, and correspondingly receive, more and more mail.

WHY PEOPLE LOVE THIS HOBBY

Unlike receiving mail from someone you know, this is about receiving a message from a stranger. You never know whether the next card will come from Finland, Japan, Brazil, or a tiny island you have never heard of.

Postcards often contain brief personal notes about daily life, festivals, weather, or traditions. These small messages provide wonderful glimpses into cultures across the world.

A GLOBAL COMMUNITY

As of March 2026, Postcrossing includes more than 805,000 members across 207 countries and territories. Russia, Taiwan, and the United States have the largest number of registered members, while Germany leads the world in the total number of postcards sent.

India currently ranks 27th globally, with more than 11,500 active members. The community also celebrates World Postcard Day on 1 October, marked by exhibitions, writing events, and special postal cancellations.

MILESTONES AND CELEBRATIONS

On 19 January 2026, the 85-millionth postcard was registered. To mark the platform’s anniversary in 2025, bpost (the Belgian postal service) released a special sheet of stamps celebrating two decades of the initiative.

Several countries have also issued Postcrossing-themed postage stamps, including recent releases from New Zealand, Poland, and the Netherlands. Local meetups are another tradition; enthusiasts sometimes gather at post offices or community events to exchange cards and celebrate the hobby together.

SMALL CARD, BIG STORY

At its heart, Postcrossing is about rediscovering the charm of slow communication. A postcard travels thousands of kilometres to arrive with a handwritten message from someone you may never meet.

In a world where communication is often instant and fleeting, that small card becomes something rare: a tangible connection between strangers. Perhaps, that is the real magic of Postcrossing.
