Free tools for mailing letters
Each of these tools answers one question about a letter before or after you mail it, and none of them needs a PigeonTrail account. They follow USPS's own rules and prices, and each tool's page shows the date we last checked them.
Will my envelope go as a letter?
The letter checker runs USPS's size, thickness, weight and stiffness rules on a mailer and tells you whether it goes as a letter, whether it is machinable and how many stamps it needs. It starts from the setups card sellers mail most, such as one card in a toploader in a #10 envelope, which goes for one Forever stamp. Check a mailer with the letter checker
How long will my letter take?
The delivery time tool asks USPS's service standards how many delivery days a First Class letter gets between two ZIP codes, then counts them out on the calendar, skipping Sundays and postal holidays, to show the day to expect it. Find a letter's delivery time
How long does mail take from one state to another?
The mail time map shades every state by the number of days USPS most often gives a First Class letter from the state you pick, and each state has its own page with the usual days to all 50 states and Washington, DC. The numbers come from USPS's own service standard directory, weighted by where people live. See mail time by state
How do I print an address on an envelope?
The envelope template prints a #10, A7, 6 x 9 or custom envelope from your browser, with the address where USPS's machines read it and the barcode strip left clear. Nothing you type is sent to us, and the template remembers your return address in your own browser. Print an envelope with the template
What does the barcode on this envelope say?
The barcode decoder reads the bars of a USPS Intelligent Mail barcode, or the digits printed with it, and shows its barcode ID, service type, Mailer ID, serial number and ZIP Code with a plain explanation of each. It runs in your browser and never makes a barcode. Decode an Intelligent Mail barcode
