At nearly all of the American National Park units (and many of the National Park Service's affiliated areas), one or more National Park Passport Stamps (cancellation stamps) can be acquired at no cost. The Passport program is run by Eastern National, a non-profit organization. The program began in the middle of 1986. Over 1,300,000 Passport books have been sold. In 2006, for the program's 20th anniversary, the "Passport Explorer" was released ^*, featuring a binder and larger pages.

Passport stamp ink comes in various colors depending on which of the 9 passport regions one obtains the stamp. The regions (and their colors) are:

• North Atlantic (brown)
• Mid Atlantic (light blue)
• National Capital (red)
• Midwest (orange)
• Southeast (purple)
• Southwest (gray)
• West (green)
• Rocky Mountain (gold)
• Pacific Northwest and Alaska (blue)

In addition to the cancellation stamps, one can also buy adhesive stamps to affix to the Passport book. These stamps are issued each year. They feature a photo and description of one park per region, with the parks changing each year.
