.NET PLANET Generator for .NET, ASP.NET, C#, VB.NET

USPS Confirm service allows mailers to uniquely identify and track mail by placing an additional barcode, known as a PLANET Code, on the front of letter and flat mailpieces. The PLANET Code is a 12 -or 14- digit barcode - a ?wo-state?barcode similar in structure to the POSTNET Code address barcode used by mail processing equipment to sort the mail.

PLANET Codes consist of a series of tall and short bars. PLANET Code digit Symbology is the inverse of POSTNET Code digit Symbology; each POSTNET Code digit uses a combination of two tall and three short bars; each PLANET Code digit uses three tall and two short bars. PLANET Codes must begin and end with one long "framing bar".

All PLANET Codes include a check-sum digit or correction character. This digit must always be the single-digit number (i.e., 0?) which, when added to the sum of the other digits in the barcode, results in a whole number that is a multiple of 10.

Depending on the type of Confirm mail, mailers must choose the appropriate PLANET Code format:

Destination Confirm to track outgoing mailings. PLANET Codes can be used to identify mail sent to customers
Origin Confirm to track incoming mail. PLANET Codes can be used to identify reply mail that customers send back

The Destination Confirm PLANET Code consists of the following elements:

Service Type ID: The first 2 digits represent the service (i.e., Destination Confirm) and the class/shape of the mail. Destination Confirm Service Type IDs are listed below
Subscriber ID: The next 5 digits identify the subscriber (assigned by the Postal Service)
Mailing ID: The next 4 or 6 digits are available to the mailer to use for their own identification purposes (e.g., mailings, clients, etc.)
Check-Sum Digit: The 12th or 14th digit is a check-sum digit that helps the Postal Service to detect errors

Service Type IDs for Destination Confirm service:

40 - First-Class Mail letters
41 - First-Class Mail flats
42 - Standard Mail letters

The Origin Confirm PLANET Code consists of the following elements:

Service Type ID: The first 2 digits represent the service (i.e., Origin Confirm) and the class/shape of the mail. Origin Confirm Service Type IDs are listed below
Customer ID: The next 9 or 11 digits are available to the subscriber to help identify the customer (i.e., mailer of reply mailpiece) or the reply mailpiece itself
Check-Sum Digit: The 12th or 14th digit is a check-sum digit that helps the Postal Service to detect errors
