Opening a P.O. Box

To my knowledge, in HCMC you can't open a P.O. Box online.

In Thailand check these links.

But I don't  anymore know whether you can open up these P.O. Boxes online.
Maybe possible at PhuketPostbox. But the "open your box online" page is under construction for longer time. 

I live in Thailand and Vietnam................you have to be in-country and have a valid Visa before you can open a PO Box..........you can't do it on line, - I have three PO Boxes and a Condo mailbox  -  all had to be done in person, with passport and proof of residency.  Think of it this way - whats to stop you from mailing contraband to them and giving someone else your key to pick it up??   I don't know anywhere in the world where you can open a PO Box and not live there, that would be an accident waiting to happen.

You can however, mail things to yourself to the Bu Dien in your own name General Delivery, but you have to pick it up................so why d you need this PO Box..........just curious.

Would a virtual postal address with scan and forwarding also be an option for you?
