Recently, USPS intentionally made a change to the Preview label. The Preview on Step 3 of the Single Label process is intended to show the cost of the label with the mail options chosen on Step 3 and to test your printer. This Preview label is not intended to show if you typed the address information correctly. You can see the information that was typed on Step 1 and Step 2. You can go back to Step 1 and Step 2 as many times as you need. USPS is in control of the label layouts; unfortunately we have no control over their format.
