Hi,
Does anyone know if Amazon can check the tracking number we put in is valid or not ? I have a usps tracking number file but it gets some errors and cannot check with the carrier website and I'm worried that put them in will affect the "Valid tracking rate" if they mark them as invalid.
I would be glad if anyone could advise me for this. Thank you in advance.
