/** imd Intelligent Mail Barcode - Onecode - USPS-B-3200
 * Intelligent Mail barcode is a 65-bar code for use on mail in the United States.
 * The fields are described as follows:
 * 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 90–94.
 *
 * The Service Type Identifier shall be assigned by USPS for any combination of services
 * requested on the mailpiece. The allowable encoding range shall be 000
 * 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.
 *
 * 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- 899999, while the allowable encoding range for the 9 digit
 * Mailer ID shall be 900000000-999999999.
 *
 * The Serial or Sequence Number shall be assigned by the mailer for uniquely identifying and
 * tracking mailpieces. The allowable encoding range shall be 000000000–999999999 when used with a
 * 6 digit Mailer ID and 000000-999999 when used with a 9 digit Mailer ID. e.
 * The Delivery Point ZIP Code shall be assigned by the mailer for routing the mailpiece.
 * This shall replace POSTNET for routing the mailpiece to its final delivery point.
 * The length may be 0, 5, 9, or 11 digits.
 * The allowable encoding ranges shall be no ZIP Code, 00000–99999,
 * 000000000–999999999, and 00000000000–99999999999.
