Barcode on mail in window
You're referring to the barcode that appears on the window of a mail-in envelope!
The barcode on the window of a mail-in envelope is called a "mailing label barcode" or " Intelligent Mail barcode" (IMb). It's a unique identifier that helps the United States Postal Service (USPS) track and sort mail more efficiently.
Here's what you need to know about this barcode:
- Purpose: The barcode helps the USPS to quickly and accurately identify the sender, recipient, and contents of the mailpiece.
- Format: The barcode is a 65-character code that includes the sender's and recipient's addresses, the mailpiece's weight, and other relevant information.
- Placement: The barcode is typically printed on the top-right corner of the envelope's window, which is the transparent area on the envelope that allows the USPS to scan the barcode.
- Benefits: The barcode helps to:
- Improve mail sorting and delivery efficiency
- Reduce errors and misdirected mail
- Provide real-time tracking and monitoring of mailpieces
- Enable the USPS to generate reports and analytics on mail volume and trends
- Requirements: The USPS requires that mailers use the Intelligent Mail barcode on certain types of mail, including:
- First-Class Mail
- Priority Mail
- Priority Mail Express
- Parcel Select
If you're a mailer, you can generate the Intelligent Mail barcode using a barcode font or a software application that supports the USPS's barcode format.
