A P.O. Box can be used as a mailing address but not as a domicile address. US trademark applications require both.

The mailing address is the address used for correspondence with the USPTO and is publicly visible in the TSDR database. The domicile address is your actual place of residence or business and is required to establish jurisdiction. It is not published publicly but must be provided in the application. A P.O. Box cannot satisfy the domicile address requirement.
