I have had multiple packages coming from China with tracking numbers starting with AM, these packages do not show as valid in the destination country. I have been told all international tracking codes start with either U, L, C or E. Are the tracking numbers fake?

I need a USPS tracking number for my package that they said was delivered today. can't check with Post Office without a tracking number.. The tracking number I have is from China - it is AQ017387734CN. I also called the phone # listed on website ( +86 10 11185 and also tried calling +86 20 11185 )-- neither number would go through states is an invalid number.
