What Is Upsm

What does the post say UPSM? what's this? 3

Is it just UPS or USPS? I never heard of it either. But my package says it is being sent via UPSM. Can anyone be angry? This is important because I provide my shipping address by mail. Box hahaha I need to know if it needs to be changed or not because USPS sends it to voicemail and not UPS.

ups united post service M means courier service used for courier and I would like to ask Best Buy who can tell you which shipping service they use and provide a tracking number.

Both UPS and FedEx have agreements with the postal service. It is shipped with independent carriers and then transferred to USPS. W delivers the package to the destination.
