* The fields are described as follows:<ul><li>The Barcode Identifier shall be assigned by USPS to encode the
* presort identification that is currently printed in human readable form on the optional endorsement line (OEL)
* as well as for future USPS use. This shall be two digits, with the second digit in the range of 0–4. The
* allowable encoding ranges shall be 00–04, 10–14, 20–24, 30–34, 40–44, 50–54, 60–64, 70–74, 80–84, and

* on the mailpiece. The allowable encoding range shall be 000http://it2.php.net/manual/en/function.dechex.php–999.
* Each 3-digit value shall correspond to a particular mail class with a particular combination of service(s). Each
* service program, such as OneCode Confirm and OneCode ACS, shall provide the list of Service Type Identifier
* values.</li><li>The Mailer or Customer Identifier shall be assigned by USPS as a unique, 6 or 9 digit number
* that identifies a business entity. The allowable encoding range for the 6 digit Mailer ID shall be 000000-

* used with a 9 digit Mailer ID. e. The Delivery Point ZIP Code shall be assigned by the mailer for routing the
