Cardzilla is an international community for people who love real postcards, handwritten messages, and connections with people around the world.
In a world where almost everything has become digital—emails, messengers, social media, and AI-generated content—receiving something real has become truly special. A paper postcard travels thousands of kilometers before reaching your mailbox. Someone chooses it, writes a personal message by hand, puts a stamp on it, and sends it especially for you.
A real postcard is much more than just a picture. It is a small piece of another country, another culture, and another person's life. You can hold it in your hands, read the handwritten message, keep it in your collection, and remember the person who sent it for years to come.
Cardzilla was created for exchanging real physical postcards, not digital images or virtual greetings. Every postcard on Cardzilla is meant to be printed on paper, written by hand, stamped, and delivered through regular mail.
Whether you enjoy surprises or prefer choosing exactly which postcards you exchange, Cardzilla gives you both options.
Cardzilla offers two different exchange modes. You can use either one—or both at the same time.
Love surprises? This mode lets you exchange postcards with completely random people from around the world.
Step 1. Complete your profile
Create your account and fill in your profile. Don't forget to add your postal address so other members can send postcards to you.
Step 2. Request a random address
Click the button to receive a selection of other Cardzilla members. The system will offer you several people who are currently waiting for a postcard, and you can choose the one you would like to send your postcard to.
Step 3. Send your postcard
Choose a postcard, write a friendly handwritten message, add stamps, and mail it to your new postcard friend.
Step 4. Wait for your own surprise!
Sooner or later another random member will receive your address and send a postcard to you. Every trip to your mailbox becomes a little adventure—you never know which country your next postcard will come from. When you receive a postcard, make sure to register it on Cardzilla so the sender gets a notification that it has been successfully delivered.
Have postcards you would like to exchange with specific collectors? Direct Swaps are perfect for you.
Step 1. Upload your postcards
Add photos of the postcards you are willing to trade to your personal gallery. Other collectors can browse your collection and find cards they would love to receive.
Step 2. Send or receive swap offers
You can browse other members' galleries and propose exchanges yourself, or simply wait until someone contacts you.
Step 3. Agree on the exchange
Discuss which postcards each of you will send. Once both sides agree, confirm the swap on Cardzilla.
Step 4. Mail your postcard
Write a personal message, prepare the postcard, and send it through regular mail.
Step 5. Receive your swap!
After your partner sends their postcard, all that's left is to wait for it to arrive. Once it reaches your mailbox, register it on Cardzilla and enjoy adding another beautiful postcard to your collection.
Whether you're sending your very first postcard or already have hundreds in your collection, Cardzilla makes international postcard exchanging simple, friendly, and enjoyable.
