Say you're planning a bicycle trip across the United States, a three-month summer excursion or a similar long trip. You know what you like to eat while pedaling, what clothes you'll want in different climates and what supplies you'll need during the various stages of your trip. The U.S. Postal Service general delivery option, according to spokesman Norm Scherstrom, could be your answer. It was designed to provide services to people in transit.
Every ZIP code provides general delivery receiving in at least one post office.
It's a particularly helpful service if you're sending yourself specialty bike part items or diet-specific food in a relatively remote area not likely to have a sporting goods store, for example. You should allow the same amount of time to mail your package as you would for any package, but not too much time. As you plot out your route, you'll need to know the ZIP codes of any towns to which you'll be mailing items to yourself. You'll need to provide ID to pick up your package. So you'll need to research the requirements in the countries you plan to visit.
