The anticipation for the total solar eclipse is building, and for 29 Post Offices in Idaho, that excitement will be celebrated with special local postmarks available on Monday, Aug. 21, the date of this once-in-a-lifetime celestial event.

The commemorative postmarks will be applied to envelopes, cards or any other items bearing First-Class postage stamps, including the Postal Service’s Total Eclipse Forever Stamp issued last month – the stamps themselves are the first of their kind, with the depiction of the eclipse revealing a photo of the moon when the heat from your finger touches the stamp.

Here are the Idaho Post Offices issuing special postmarks celebrating next Monday’s eclipse: Arco, Ashton, Cambridge, Cascade, Donnelly, Driggs, Dubois, Hamer, Howe, Idaho City, Idaho Falls, Idaho Falls - Eagle Rock Station, Ketchum, MacKay, Menan, Midvale, Moore, Payette, Rexburg, Rigby, Ririe, Roberts, Shelley, Stanley, Sun Valley, Terreton, Tetonia, Victor and Weiser.

The Special Postmarks all share the same design with the exception of the City and ZIP Code, and will be available at the 29 Post Offices on Aug. 21, or at a temporary Post Office at a local Total Eclipse Event. Check with your local Post Office for information on where the special postmark will be available on Aug. 21. 

Postal customers may also obtain a postmark from any of the locations via the mail by sending a self-addressed stamped envelope inside another, larger envelope, to any of the 29 Post Offices on the list above using the following address format:

Mailed self-addressed, stamped envelopes will be postmarked at the appropriate city and then returned via regular mail. Postmark requests must be mailed to each Post Office individually to obtain that city’s postmark. Mailed requests for postmarks must be sent no later than Sept. 21, 2017, in order to be fulfilled.

The Postal Service receives no tax dollars for operating expenses and relies on the sale of postage, products and services to fund its operations.
