What:

On Thursday, Sept. 21, the Serra Mesa Post Office will commemorate a once-a-century alignment of the date on the calendar--9.21.23--with its ZIP Code--92123.

The alignment of calendar dates with ZIP Codes occurs only once a century and in relatively few locations nationwide.

The alignment will be marked by the sale of special commemorative envelopes at the Serra Mesa Post Office that feature a “92123 Date Meets ZIP” postmark, as depicted above. The special postmark will also be available at that office to cancel mailable items presented by customers.

Serra Mesa residents are invited to visit their Post Office to enjoy refreshments, obtain the commemorative cancellation and purchase the special envelopes, which will be available while supplies last.

“We’re excited and honored to host this rare event,” said Serra Mesa Post Office Manager Francisco Avila. “It recognizes the unique ties between USPS and our community. As outlined in USPS’s Delivering for America plan, we are committed to serving the changing needs of our customers nationwide, from Syracuse to Serra Mesa.”
