Why my Tracking No. is Invalid, I can't track it online?

---

This situation happens maybe for the following points:

1. The Express company hasn’t updated the recent delivery information on their website. Sometimes, it will have about 1 day delay.

2. The tracking code was not correct. Please contact our customer service to check the tracking No.

3. The parcel has been delivered a long time ago. Some shipping companies will remove the tracking code history. 

If you are not sure, please contact us, we will check with the express company for you.
