Delivery is not guaranteed by a definite time period, however, most locations can expect delivery within 3- 5 business days.
Some countries provide service to all points, while others have a restricted list of cities.
Unlike domestic express mail, if a given city is not serviced, the piece cannot be sent to the country at all. The country will return it to the sender. It is important to check with Mail Services about availability before filling out express forms. Mail Services keeps a supply of forms and international express envelopes. Return receipt service is available to some countries.
