Populating the Mail.dat field code MPA-1110 Customer Reference ID using MailStream Plus

Product Affected:  MailStream Plus™, All platforms

 
How do you populate the Mail.dat field code MPA-1110 which is the Customer Reference ID using MailStream Plus™?

This is populated with the PA INF parameter using the subkeyword 'MDMFCR' or subkeywords 'MDMFCR' and 'MDMFC2'.  
Add a PA INF indicating the piece id code starting in position 14 and the Customer Reference ID starting in position 35, it would look like this:

PA INF       PID1          MDMFCR 12345
....+....1....+....2....+....3....+....4....+.

 
  • The MPA-1110 field code is a 40 byte field.
  • The subkeyword MDMFCR is 30 bytes. 
  • If the value for the Customer Reference ID is over 30 bytes, the PA INF with MDMFC2 can be used to populate the last 10 bytes.
 
PA INF       PID1          MDMFCR 123456789012345678901234567890
PA INF       PID1          MDMFC2 12345
....5...10...15...20...25...30...35...40...45...50...55...60...65...

Note:  The MDMFCR will also populate the 'CAPS Cust. Ref. No.' on the USPS statements. 

Refer to the MailStream Plus Guide for a full explanation of all parameters.
