* on the mailpiece. The allowable encoding range shall be 000http://it2.php.net/manual/en/function.dechex.php999.
* 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
