Although postcard collecting is quite popular in America and Europe, it's hardly so in Japan. Which means there aren't really any postcard collector's clubs here. So it is quite a relief to find such a group.

Wildlife postcard exchange. Also a site with free email greeting cards, news and links.

Collecting and exchanging with online auctions.

Social group to exchange and discuss postcards.

All deltiologists (postcard collectors) are welcome to attend. The goal of the club is to promote the hobby of postcard collecting in Hawaii - and elsewhere

Postcard exchange club at Yahoo.

Group who scan and then send postcards to each other from around the world.

Hilary sends postcards to those who ask for them. When you get a postcard send a photo to the group showing it off.

Make a postcard, send a postcard. The recipient does the same. Scan the postcard and post it on this group.

This group is set up for postcard collectors. Exchange postcards with others and share scans of the cards in your collection.
