Pitney Bowes DM125 User Manual

This is an administrative application used to establish mail-
ers in the confirmation services database. This form is 
required of any customer who wishes to use Delivery Con-
firmation, Signature Confirmation or Certified Mail. Mailers 
applying to use these services complete the application 
and fax it to the number provided on the form or mail the 
form to the address listed. A key element of the application 
is the Mailer ID (MID) number for the company applying.

Customers use this form to register for the Certified Elec-
tronic Return Receipt (ERR) service. Customers must 
enter their 9-digit Mailer ID (MID) provided to them from 
the USPS online tool (see previous page). This same MID 
must also be entered into their postage meter to complete 
the process.

This is required only for those customers who wish to re-
ceive daily detail extract files from the USPS 16 times a 
day. Such customers can update their own systems with 
this tracking data.

IMPORTANT! The application process cannot be completed 
without Forms 5053 and 1357. 

This form allows the USPS to verify your Mailer ID (MID) 
number and check that your barcode printing software is 
certified. This is for customers who want to print their own 
certified labels. This form is required in addition to PS Form 
5051.
