The International Society of
World Wide Stamp Collectors

Welcome to the ISWSC

The International Society of Worldwide Stamp Collectors serves the interests of all worldwide collectors. It strives to promote the fun and fascination of worldwide stamp collecting to young and old alike, and has an active outreach program serving youth, their leaders and beginners of all ages.

Look at the benefits we have to offer. We'd like to hear from you!

Officer Elections

All three society officers have been re-elected for the 2018-2019 term, according to executive director Joanne Berkowitz. They ran unopposed. Returning are John Seidl as our president, Bob Armstrong as our vice-president and Mike Clark as our secretary. Officers are elected for two-year terms beginning in the even years. Kudos to our mighty triumvirate, and thanks for serving!

About Us

Responding to a letter by Society founder Aubrey Dunne published in Linn's Stamp News, seasoned worldwide collectors let it be known that they were tired of the "amateur" image given them as non-specialists. The foundations were laid in 1980 for what is now the International Society of Worldwide Stamp Collectors.
