About Oklahoma Philatelic Society
The Oklahoma Philatelic Society is the largest, nonprofit stamp collector organization in the State of Oklahoma. Whether you are a beginning collector or have years of philatelic experience, the OPS offers you a number of services and educational opportunities to broaden your personal collection and enhance your special collecting interest!
OPS is supported entirely by membership dues, gifts, and the sale of its publications and services. Founded in 1932, the OPS is now in its 81st year of service to stamp collectors and postal historians.
No matter what you collect, OPS membership will help you find a willing group of collectors to share your particular collecting interests.
