The PLANET Generator creates a scannable PLANET barcode image from any text or number you enter, ready to download and use in USPS outbound mail tracking.
PLANET (Postal Alpha Numeric Encoding Technique) is a USPS barcode used on outbound mail pieces to enable real-time mail tracking services.
Developers, warehouse operators, and businesses use this generator to produce real, standards-compliant barcode images without needing dedicated barcode software.
Different barcode symbologies exist because different industries have different requirements — data density, character support, error tolerance, and printing space all vary by use case. PLANET was designed and adopted specifically for USPS outbound mail tracking, which is why it remains the standard choice in that context.
Choosing the right barcode format for your application matters, since scanning equipment and industry standards are often built around a specific symbology.
