An alternative to Panama’s national postal service, which is not the World’s fastest, nor its most reliable, is a P.O. Box in Miami with a forwarding service to Panama.
There are a few private companies who make this process a very simple one, pricey, but simple. Aerocasillas and Mail Boxes Etcetera are the leading providers of this mail service. Sending and receiving mail through these companies generally takes about 3 to 5 days longer than it would if mailed within the United States and costs about 30-40 percent more.
As a rule these mail forwarding services are fairly, reliable and quick, and although a little expensive, currently the best substitute for FedEx, DHL and Panama’s national postal service.
