I have no problem with this. UPS and Fed Ex regularly cannot find my rural home. USPS finds it every day.
The USPS delivers mail to every street address on a near daily basis. The private carriers don’t, nor do they have carriers who walk routes and who often know the residents living on their routes quite well.
People like to complain about the bankrupt USPS, but their problems are entirely caused by congressional micro management in regards to unionization and forced payments to prepay their excessive medical and retirement plans (so congress can raid that piggy bank).
My experience is EXACTLY the opposite. USPS is worthless.
