How to get my USPS track number?

I come from China, and I bought LPU pack two months ago.
But I haven’t received it yet.
I don’t know the USPS track number, so I can’t check the mailing information./(ㄒoㄒ)/~~
Who can help me?

The shipment number is GC7IPYT13T

Tracking number isn’t included if you chose the standard shipping. If you have issues just contact support and they’ll help you.

If you can give the office where you sent the item the date and an approximate time that it was sent, the clerk who handled the transaction and the total amount of the receipt, it’s not difficult to look up and print a copy of it. That would have the tracking number on it. You can also get the help from Lite Blue portal.

Thanks.
