Higher error correction lets the code survive damage and logos, but makes it denser. Auto uses H when a logo is added.

Getting your IMb numbers

The tracking code includes your Mailer ID from the USPS Business Customer Gateway. Postage discounts require meeting USPS automation standards; this tool creates the barcode image only.

Frequently asked questions
