USPS Transition From Uspod

I know the United States Postal Service replaced the Post Office Department in 1971, but I can't seem to find specific information on the transition. The government typically operates on a fiscal year, so October 1 would seem like a logical date, but I have not been able to locate the exact date.

Anyone here know?

Wikipedia says July 1

Thanks rlsny! I saw that page, but not see the block on the right side.

That is interesting. I have a first day program portfolio for the Wildlife Conservation Issue dated June 12, 1971 that has the USPS logo.

It was 7/1/71. The US Government fiscal your was July 1-June 30 back in those days.

Morning all,

The USPS was slow in issuing new postmarking devices (or folks just used what they had on hand) after July 1, 1971 that said "USPS" not "USPO". Is anyone aware if and when they said older "USPO" devices were declared obsolete and no longer valid for use? What is your earliest example of a circular dater device that says "USPS"?

Best regards,

Russ,

I think I misstated the item that I have. It appears to be a special portfolio that was provided to a dignitary, Myron A. Wright who was one of the original members of the Board of Governors of the USPS.

It contains a full sheet of the Wildlife issue along with the first day ceremony program from Avery Island and a public relations pamphlet from the Humble Oil and Refining Company in Houston, Texas. It was mailed from Avery Island using a plate block cancelled on the first day. Wright was a Chairman of the Board of that company.

My guess is that the portfolio was created after the USPS officially stood up and provided to Wright after June 12, 1971.
