Organized October 8, 1886, continuing the Chicago Stamp Collectors Union, which was organized December, 1884. The CPS is APS Chapter No.1, and one of the two organizations with the longest uninterrupted service to philately in the United States.

The Chicago Philatelic Society holds monthly stamp meetings (on the third Thursday of each month) in Downtown Chicago at the Harold Washington Library (400 S State St); the meeting room is posted at the entrance. Meetings run from 7:00 to 9:00pm, and usually include a philatelic presentation and some society business. All are welcome. Many of our speakers are advanced collectors, so be prepared to see exciting stamp and postal history subjects. Many of the members have an informal dinner before the meeting at the Berghoff Restaurant (17 W. Adams St.) at about 5:30pm. 

Each year in November we host CHICAGOPEX — one of the four largest stamp shows in the country — that attracts dealers, exhibitors and stamp enthusiasts from around the nation and the world. Click on either CHICAGOPEX selection (at left) to see information about this year's and future stamp shows.

We invite you to visit us or attend a meeting. Our members are more than happy to answer any questions you may have about the organization and how you can join.
