Where USPS Intelligent Mail is used
US mail automation, combining routing and tracking into a single four-state barcode.
Printing USPS Intelligent Mail on a thermal printer
A generated image is fine for a one-off. For a production run you want the barcode rendered by the printer at its own resolution, sized in whole dots so the narrow bar lands on an exact dot boundary. LabelInn does that on Zebra, TSC, Toshiba and Epson hardware, and it can drive one label per row straight from your data.
Frequently asked questions
Is this USPS Intelligent Mail generator really free?
Yes. The generator runs entirely in your browser, there is no signup, and the downloads carry no watermark.
Does my data get uploaded anywhere?
No. The symbol is encoded locally in your browser. Nothing you type is sent to a server.
What can USPS Intelligent Mail encode?
numeric. Length: 20 or 25 digits, rendered as 65 four-state bars. Check digit: built into the 4-state encoding.
Can I print USPS Intelligent Mail labels in bulk from a spreadsheet?
Not from this page — this tool makes one symbol at a time. LabelInn binds a spreadsheet column to the barcode field and prints one label per row on a thermal printer.
Printing USPS Intelligent Mail labels in production?
This generator makes one symbol. When you need a batch — one label per row from a spreadsheet, a database or your API — LabelInn renders USPS Intelligent Mail natively on the printer at its own resolution.
