UC153784461YP is not China Post tracking number. it is Yanwen parcel number. There is an actual china post ordinary tracking number associated with this yanwen parcel number, but Yanwen does not tell you the real China Post tracking number. So you can not use UC153784461YP to track the status in China Post website.

Actually Yanwen not only use China Post ordinary parcel to ship goods. It also use Vietnam Post, Malaysia Post, Netherlands Post ordinary parcel to ship the goods. Normally Yanwen won't tell you what is the real tracking number and real post service they are using. When you use Yanwen number to track the parcel, Yanwen software will automatically lookup its real tracking number from original post office and then return the result to you in Yanwen website.

you no need to know which post. it can be Vietnam Post, Malaysia Post....Yanwen does not tell you.

Different post companies offer different discount price to Yanwen every hour depending on their shipping space situation, goods type and many other factors. Yanwen uses the cheapest service for each specific parcel based on its condition.

So every parcel can be different post. You can not know.

Unfortunately, you can NOT track these U parcel update. i don't think the result of "arrive at your country" from Yanwen is true. Yanwen can not know if it has arrived your country.
