To start buying postage online, all you need is a printer and a subscription to a PC Postage service such as Stamps.com. Here’s how it works:

  1. Connect to Stamps.com to buy postage online
    Our free software (download here) will connect you via the Internet to your Stamps.com Postage Account. When you print postage, the postage amount will be deducted from your account.
  2. Input or choose an address from your address book
    Stamps.com imports delivery addresses automatically from your MS Outlook, QuickBooks and many other popular address book and contact management software. You can add or edit addresses anytime. You can even print postage directly from MS Word, Outlook and Corel WordPerfect.
  3. Weigh your package using your free 5 lb. digital scale
    Use the free Stamps.com 5 lb. digital scale (just pay shipping and handling) to accurately weigh your envelopes or packages — you’ll never overpay or underpay for postage again! The scale connects directly to your PC and integrates seamlessly with the Stamps.com software. If you need to weigh heavier packages you can upgrade to our 35 lb. scale anytime.
  4. Instantly calculate and print your exact postage
    Stamps.com allows you to buy the exact postage amount you need for your letter or package. You can print your postage on standard labels, envelopes or plain paper. In addition, Stamps.com will give you an estimate of the delivery time of all available USPS services, so you can choose the most cost-effective mail class based on your needs. Stamps.com uses the USPS database to validate your delivery address, ensuring fast, accurate delivery. Stamps.com can even send an email to the recipient to inform them that the package is on its way.
  5. Send it off
    Simply apply your Stamps.com postage to your mailpiece and either hand your letters and packages to your Postal Carrier, schedule a USPS pick up, drop them at the Post Office (without standing in line) or put them in a mail collection box. Plus, when a package of 13 oz. or more displays postage printed from Stamps.com, the USPS allows you to bypass the 13 oz. limit restriction and drop it right in a mail collection box!
  6. Track packages and view history
    Stamps.com automatically keeps a detailed record of the postage you print. This makes it easy for you to review your postage spending or to print a report for your files. And, with Stamps.com “one-click package tracking,” there is no need to type long tracking numbers to verify your package delivery.
