The Postal History Foundation

We measure the value of stamps, not in cents, but in smiles.

Our services

The Postal History Foundation serves the community with a museum, library, philatelic store, contract post office, and learning materials.

Education & Outreach

The Stamp Discovery Education Program supports educators, parents, students, scouts, organizations, and the community through several free or nominally-priced services and resources.

Library & Archives

Our premiere Slusser Library holds over 30,000 titles, primarily related to stamp collecting and postal history. We also have an archives with hundreds of boxes and dozens of feet of research material.

Philatelic Store

Our philatelic store supports collectors, strengthens the hobby of philately, and provides part of our funding that keeps us going.

Cultural Exhibits

The Foundation teaches on-site and virtual visitors through our physical and digital exhibits, which range from Arizona Territorial postal history to modern-day postage stamps.

On-site experience

Guided tours of the facility include not only our cultural exhibits, but also a behind-the-scenes look at our volunteer workforce processing thousands of postage stamps!

Contract Post Office

There’s rarely a line at our post office! Our post office is the only philatelic sales facility in all of Arizona, and we’re also the only postal outlet in the state with most new stamp issues.

We can’t do it without you.

The Postal History Foundation is a non-profit 501(3)(c) organization dedicated to promoting stamp collecting and postal history. We specialize in using postage stamps to educate youth in all subjects.

We rely on gifts, donations, and memberships to carry out our mission.

The Foundation provides classroom support with lessons, stamps, field trips, and guest speakers. Organizations from all over the country order lessons and stamps to share with children. Your donations help us continue this important work.


What is my stamp worth?

(And other important questions!)

We’ve compiled a list of our Frequently Asked Questions to help you navigate the world of philately.

Including how to pronounce philately.

And what philately means.

Who are the Arizona Philatelic Rangers?

Founded in 1960 alongside the Postal History Foundation (then known as the Western Postal History Museum), the Arizona Philatelic Rangers was organized as an independent sponsoring society to finance and staff the museum.

The accomplishments of the museum were also the successes of the Rangers. There’s no doubt that the early efforts of the Rangers’ support and fundraising activities were the most significant element in the growth, stability and success of the Western Postal History Museum.

The Rangers remain an important philatelic organization and meet frequently at stamp shows around the nation.
