Is myUKmailbox a P.O. Box or a real physical address?

It's a real physical address. Not a P.O. Box.

Your parcels are delivered to our warehouse in Sheffield, where our team signs for them.

We accept deliveries Monday to Friday, 8:00am to 4:30pm UK time.

Courier turns up outside those hours? They'll try again on the next working day. The major couriers know our hours.
