    A bad address can cost a business time and money. Endicia verifies addresses against the USPS database and then automatically corrects and standardizes the address for you.

    Sometimes you just need an occasional stamp instead of a full shipping label. DYMO Stamps allows you to print stamps with exact, no-expiration postage for addresses on the label.

  • Stealth Postage™

    Stealth Postage helps you avoid upsetting customers by replacing the dollar amount of postage with the words "U.S. Postage and Fees Paid." Customers won’t be confused by the shipping and handling fees you charge vs. the amount you paid for postage.
