The answer to this question is a little complicated, as both DHL Express and USPS do use each other’s services from time to time. However, in general, DHL Express does use USPS more frequently than USPS uses DHL Express.
In general, DHL Express uses USPS for shipping smaller packages that don’t require a signature. USPS, on the other hand, uses DHL Express to ship packages that are too large or too heavy to be shipped through the mail.
However, both services sometimes use the other’s services when they are better suited for the task at hand. For example, USPS uses DHL Express to ship packages to international destinations, while DHL Express uses USPS to ship packages within the United States.
In conclusion, it is true that both DHL Express and USPS use each other’s services from time to time. However, overall, DHL Express uses USPS more frequently than USPS uses DHL Express.
