Will anything I mail to a post office box be accepted by the post office and held for the recipient?

Question

I want to send about 18 very medium sized boxes through the mail, probably 15 pounds each. If I do, will he post office be cool about holding them there under the post box name for my friend?

This is in the US- AZ. I am shipping within state.

I had no idea where to put this...so sorry if it's in the wrong catagory.

Answer 1

The post office should hold these packages.  You would have a much smoother transaction if you were to send UPS or FEDEX.  Call your local USPS for the most accurate answer.  I used to send and receive medium size boxes all over the US via USPS with no problems.
