This is the Ukarumpa Post Office. It is located centrally in Ukarumpa across from the directors and finance offices. Through the first door you will find friendly ladies who can help you buy stamps, aerograms or send packages within PNG as well as internationally. They also keep all the larger boxes or packages behind the counter because they will not fit in the small PO boxes.
In the next room there are row after row of PO boxes. Mail gets flown in from Port Moresby three times a week and then is separated into the correct boxes. There is also a place to put mail to be distributed within Ukarumpa. This is handy in a community as large as Ukarumpa. When you need to borrow or return things it is often easier just to send it to a PO box instead of trying to catch someone at their home on the other side of the center.
This is my much mentioned mail box. Box 339 which opens with the amazing key pictured below.
