How does confirm service work?
The system applies what they call a PLANET code, or a special type of barcode, above the address in which the package is being mailed. Periodically, the bar code will be scanned while being processed on sorting equipment. The scan is then sent to our database servers via USPS. It is then outputted in a raw form which we process and display to you in an organized electronic report through our website.
We also have our own PLANET code algorithm that enables us to track each package separately. This is very helpful in a situation where you have multiple recipients at the exact same location.
