What are NetStamps?

To print and use NetStamps, consider these key details:

How to create and print your NetStamps

We provide step-by-step instructions on how to get started with NetStamps for quick and easy printing at your fingertips. Learn how to print postage stamps online with our simple guide:

  1. Navigate to the “Mail” tab in the toolbar of your Stamps.com software.
  2. Select “NetStamps” from the “Print On” drop-down menu.
  3. Enter the NetStamps sheet or roll serial number into the “Serial #” field.
    • Tip: For sheets, the serial number is located on the top right corner of each sheet. For rolls, the serial number is included on each stamp of the roll. This number helps our software identify the style and format of your NetStamps, and the preview will update accordingly.
  4. Choose how to calculate the postage amount:
    • Calculate postage amount: Use this option if you want our software to calculate the amount for each stamp. The amount is determined based on the type and weight of your mailpiece and its destination (either domestic or international).
    • Specify postage amount: Use this option if you need to print a pre-determined amount for each stamp.
  5. Select “Mail From” address (if other than default) and “Destination Country” (if mailing to a country other than the U.S.).
  6. Enter the weight of your mailpiece. If using a connected postal scale, click “Weight.”
    • We set the default weight to 1 oz, which is approximately the weight of an envelope with five sheets of paper. If your mailpiece weighs more than 1 oz, be sure to update the weight to avoid having the mailpiece returned for insufficient postage. We recommend using a postal scale for accurate weights.
  7. Select your desired service from the “Service” drop-down menu.
  8. Select how many stamps you wish to print.
    • When printing a NetStamps sheet: If you do not print a full sheet, our software will remember which stamps were printed and select the next unused stamp as the starting point the next time you print NetStamps. You can also manually select which label to start with.
  9. Optionally, you can enter a Reference Number and/or select a Cost Code, which can be useful for tracking your postage expenses and optimizing your operations.

You’re now ready to print your NetStamps! Click “Print Postage” and you’re done.

Important notes about printing NetStamps

  • NetStamps do not expire after printing.
  • The “X” marking on NetStamp rolls signals the beginning and end of the roll. This marking helps when loading the roll and lets you know when to replace it. Do not use these stamps for mailing purposes. If you accidentally print a NetStamp with an “X” marking, you can request a refund for the print.
  • You cannot print USPS postage stamps on plain paper. You must use official NetStamps sheets or rolls, which are approved by USPS for printing postage stamps.
  • You can use NetStamps for both domestic and international postcards and letters.
  • You can use a combination of traditional stamps and NetStamps on the same mailpiece as long as it adds up to the correct postage amount. For optimal delivery speed, USPS recommends putting the largest denomination in the upper right corner.
  • You can use NetStamps on either plain or window envelopes or domestic First-Class Mail Flat/Large Envelopes. However, for packages, or Priority Mail® class shipments, you must instead create and print a shipping label to ensure proper handling.
  • You can print either a partial or full NetStamps sheet. A full sheet contains 25 NetStamps. If you choose not to print a full sheet, you can re-insert the sheet into your printer and select the first unused label on the sheet the next time you print.
  • You cannot print multiple NetStamps sheets at a time. You are currently limited to one sheet per print session. Consider using NetStamps Rolls with a 2″ thermal printer if you need to print in larger quantities and scale your operations.
