Frequently Asked Questions

Common questions about the free online envelope address formatter.

Put the name on the first line, then the street, then the city, state and ZIP, and add the country only for international mail.
USPS asks for at least three lines and no more than six, with the delivery address block kept clear of other printing.
The stamp belongs in the top right corner, about 10 mm from each edge, which is why the preview marks that area.
The return address goes in the top left corner, in smaller text, so undeliverable mail can be sent back to you.
For international mail, write the destination country on its own last line in capital letters so sorting machines read it clearly.
A US ZIP code is five digits, or nine digits with a hyphen and four more for the extended delivery route.
No. The print stylesheet hides the header, footer, controls, advertising and other sections, leaving only the envelope preview.
Yes. The envelope address formatter is completely free, runs locally in your browser and stores none of your details.
