  • CO1
    • 9-digit Mailer ID
    • 9-digit zip code
  • CO2
    • 9-digit Mailer ID
    • 5-digit zip code
  • CO3
    • 9-digit Mailer ID
    • 5-digit zip code
  • CO5
    • 6-digit Mailer ID
    • 9-digit zip code
  • CO6
    • 6-digit Mailer ID
    • 5-digit zip code
  • CO7
    • 6-digit mailer ID

The software has been designed to generate only types CO1 and CO5, but it can read all 6 types listed above.  The other 4 types have been excluded because they do not include a zip code.
