Introduction

From desktop to doorstep, the Postal Service offers several online services that combine the speed of the Internet with the effectiveness of traditional mail. Online postage provides convenient alternatives for mailing at retail and offers lower prices.

Calculate Postage
Whether you’re sending a letter, large envelope, or package, our online calculators give you a convenient tool to find what your postage will cost.  You determine the shape of your item and in a couple of clicks—you’re ready to go. Mail domestically or internationally.  It’s convenient right from your home or office.

Retail/Single-Piece Calculator
Easily calculates single-piece domestic and international postage and provides estimated delivery times.

Domestic:
• Select a Shape – the question marks offer explanations of the each shape.
• Enter Weight
• Enter ZIP Code
• Click “Continue”

Results will include available pricing options, giving you a chance to compare the value of purchasing your postage online or taking your item to the Post Office. When you have to have it delivered in a certain time-frame, estimated delivery times are shown for each class of mail.  Express Mail is a guaranteed 1- to 2-day service. Add any extra services such a Delivery Confirmation or insurance and click “Continue.”  That’s it!

International:
• Choose one of over 190 countries in the drop-down box under “Select a Destination.”
• Select a Shape
• Enter Weight
• Click “Continue”

Results will be similar to domestic results in that you can view the difference in prices between printing an online postage label and taking your item to the retail counter at your Post Office.
Choose the class of mail that best suits your needs, add any extra services and click “Continue.”

A Customs form may be required for your international mailing. These are available, without charge, at your local Post Office or by ordering supplies from the Postal Store at http://shop.usps.com and then entering “customs” into the search tool.  Additional information about international mailings and customs forms can be found in the International Mail Manual (IMM®) located on Postal Explorer at http://pe.usps.com.

Locate a Post Office
The locate a Post Office tool enables you to find Post Offices or alternate Post Office locations such as Contract Post Offices (CPU) and other retail facilities that only sell postage stamps.

Track and Confirm
Tracking services provide detailed information. You will see the item scanned at acceptance, as it travels, and when it is delivered. Tracking information is available for Express Mail® mailpieces only (including Global Express Guaranteed and Express Mail International).

Services that confirm delivery are designed to be a low cost alternative to full tracking. Instead of seeing the acceptance information and updated scans as the item is enroute, confirmation services provide assurance of delivery or of attempted delivery. This service is available with the purchase of the following:

• Delivery Confirmation™ service.
• Signature Confirmation® service.
• Certified Mail™ service.
• Registered Mail™ service.
• International Registered Mail™ service.
