After more than 20 years at the post office counter, i've seen a lot of people in the envelope asking, "did i send this letter on time?" the answer is often hidden in the little stamp in the corner of the envelope。Postmark dateThe six words look simple and really understand what they mean and how they are used. It means, frankly, that all the decisions related to the "time of sending" don't look at the time you write your own date, you don't look at the time you fill out the delivery sheet, you just look at the moment that the steel stamp goes down。
What does postmark mean
You turn an envelope over and look at the back, the round roll or square stamp, except for the place names, the most important is the date and clock. Beijing 2026. 10. 16 09:30 -- this is postmark time. It represents the moment when this letter was officially incorporated into the network by the postal systemLegal effectsTime anchor. Whether the list you filled out at the express delivery station the previous night was dated october 15th, the time was not counted as long as the machine was not stamped。
I met a client who had to fight the counter with a phone screenshot and said she dropped a letter at the door at 8:00 p. M. On october 14th, and we were counting on number 15. I showed her that jab, and the box clearly says "10. 15 08:15." she was like, "oh, it's when it's stamped."Postmark dateThe point at the core -- the moment of physical stamping is the starting point, it has nothing to do with what the sender subjectively thinks is "i sent."。
How do you count the postmark
It is understood that the date on which the postmark is posted is the date of dispatch, which is time-barred and overdue. International e-mails are slightly rounded up, while stamping in the port of departure is the time of dispatch, arriving in the cover is the time of receipt, and those in the intermediate trans-shipment are merely recording the logistics trajectory and are not involved in the time limitation. A lot of people mixed up a bunch of jabs out of them。
And there's an easy pit: some postmarks areManual coverYeah. The next small post office in the village, which did not have time to cover that day, went to the district office the next day to fill in one, but the stamp was still on the date of the previous day. What day should this be? According to the postal law, the date indicated on the stamp does not depend on the actual date of operation. So just look at the stamp itself, don't guess, don't speculate, it's a day。
I used to say the same thing to the new intern: don't believe in the date of the brain. The moment the "single" fell, the moment the postal system recognized your letter. For more than 20 years, that phrase has not changed。
