I purchased an item through Amazon from a third party and the tracking number says china post but the beginning is LS#########CN. What type of mail is LS?

yes, thank you, must be still stuck in customs because it doesn't show yet

Yeah, I've had a couple of things shipped from Hong Kong and was surprised that they came so quickly, less than 2 weeks. This person is fairly new and this is the first time for me getting something from China. A little nervous, but willing to wait it out. I actually got the tracking number on the 10th, and the last email communication I had was that they thought the package was still in customs, I was just wondering how long it would stay there and when the number would show. I'm assuming when it come out of customs, but just seemed strange that it doesn't show in the system at all.

LS952107418CN

1, The tracking number LS952107418CN does not show up anywhere. Did you pay extra money to have your parcel E packet to your home in US?
If not then possibly that was a mistake of the seller.

2. If the new number you just gave me appear into your account in Amazon!
This number can be track only in China. It's call China Post Small Packet Plus, (also Pay Pall Package) it's the most economical way to send a parcel Overseas but you can not track the parcel in any country in the World.

3. This is the tracking I have for your parcel:

4. As the seller told you, it's possibly at the US Customs Office getting clear.

Hope the above information will help you.
