HOW TO POSTNET BARCODE DIFFERENT FROM OTHER BARCODE TYPES? Postnet barcode employs a unique encoding scheme optimized for mail processing, ensuring reliability, accuracy, and correct delivery of mail to the correct address. Postnet barcode uses a binary code to encode data, representing each digit as a series of five bars and spaces, with two possible states: tall or short, unlike other barcode types like UPC and Code 128. Postnet barcode is exclusively used by USPS for mail sorting and delivery, making it less widely recognized outside USPS operations. Postnet barcode is limited to encoding zip codes, zip+4 codes, and delivery point codes, making it unsuitable for encoding product information, prices, and descriptions. Postnet barcode, despite its unique encoding scheme, specialized use, and limitations, is familiar to barcode professionals due to its similar structure and decoding process. POSTNET, or Postal Numeric Encoding Technique, is a postal barcode developed in 1960s by the US Postal Service for mail sorting, tracking, and identification. POSTNET BARCODE READ AND DECODE SYSTEM: -POSTNET barcode, used for US postal services, encodes zip codes and delivery information. Scanner is required to read and decode this specific format. Postnet barcodes are decoded using specialized scanners, which capture pattern of bars and spaces in barcode, and decode it into series of numbers and letters. Postnet barcodes are read and decoded by aligning them with scanner, ensuring they are not tilted or at an angle, and then emitting light to illuminate the barcode. Scanner detects barcode pattern, decodes it into numbers and letters, and sends the data to a computer for interpretation. Barcode’s reading and decoding process requires clear, accurate printing, avoiding defects like smudging or fading, and correct size and resolution to prevent interference with scanning.
