In addition, intelligent mail barcodes are now supported. These barcodes serve the postal service by tracking and filtering shipped items and letters. Intelligent mail is becoming the new standard for USPS to organize their mailing practices.
Postnet has also been updated to meet printing standards. Postnet barcodes are generally found in a bar along the border of an envelope and are used by USPS to direct mail.
Barcode Generator offers PHP scripts to integrate barcode use into applications. They offer several standards of barcode (QRCode, PDF417, 1D, Datamatrix) to suit your needs. These barcodes can be used for ticketing, tracking, personal use, advertising, and much more.
