What is Postal Explorer?
Postal Explorer is a virtual library of postal information and tools designed for US Postal Service customers, business mailers, and employees. It puts a wealth of postal information for mailing and shipping Domestically, Internationally, and to APO/FPO/DPO destinations, at your fingertips in an easy-to-use format.

It's almost like having a full shelf of these publications - only better. Better because you only have to enter a word or phrase in the powerful search feature which lets you quickly find information in a single publication or across a range of publications. You can also view an individual publication by clicking on the publication title.

Postal Explorer is more than a reference guide. It's a mailer's toolbox that gives you the tools to design a mailing program that best suits your needs. This exciting information tool is part of the Postal Service's continuing effort to make using the mail system easier and simpler for all customers. It was developed in direct response to what you have told us, both informally and through customer surveys, about your postal information needs. It affords an unprecedented opportunity for mailers to draw on the same information used by postal employees - - with ease, speed, and convenience.

Postal Zone Charts
Postal Zone Charts display and print postal zone information specific to the first 3-digits of a ZIP Code or you may enter two five-digit ZIP Codes for specific origin and destination zone information.

Customs Forms Indicator
By entering information such as destination, weight of package, and mail service, this tool will provide you the number of the Customs Declaration Form needed for the item you are mailing, based on the customs rules relevant to your shipment. From your results, you can link directly to the necessary customs forms, enter your information electronically, and submit, all from the comfort of your computer.

Conversion Calculator
You know kilograms and centimeters, but to mail in the United States, the US Postal Service uses pounds and inches. The Conversion Calculator can quickly and easily convert your weights and measurements into American Standard.
