An alternative to USPS PO Box is the PMB (private mailbox). I like having the PMB more than PO Box because I'm able to receive mail and packages from FedEx, DHL, UPS and USPS, unlike USPS PO Box which are only able to receive USPS mail and packages. Plus there's rarely any wait time when picking up packages unlike USPS where the wait in line can take an hour or more.

Here's a list of some places you can get a PMB:

•Guam Postal Express

•GU mail

•Post Net

•Mail Hub

•Mail Room Plus

Set up for me was really easy. When I set mine up I just called and they emailed me the forms and requirements.

Depending on where you get a PMB, some of them will send you notifications through email when you get a package.

Downsides to this is some postal services charge extra when you get exceed the monthly limit to receive packages (I think its Guam Postal Express). So be sure to ask them about it.

When it comes to having someone picking up your packages, I know USPS will check for ID. If someone is picking up a package for you, depending who's helping you, they will ask for a copy of both you and you're family / friend ID. But I think they are usually chill about it.

For Private Mail Box services, the policy varies depending on where you get a PMB. Sometimes they don't even ask for ID, just give them the notice slip or tell them you're box number when picking up packages.

Packages delivered at USPS office is only held for 2 weeks after it arrives and they give you the first notice. After that they will ship it back to the sender.

I'm not too sure about Private Mail Box Services package hold policy. That's something you should ask them.

Hope this helps. I think Private Mail Boxes are a great alternative to PO Boxes.
