Which Error Codes should I mail?

Which Error codes should I mail?   
This is a question that we hear a lot  in support.  It is one of those questions that is never easy to answer.  There is no yes or no answer to this question.  There are just suggestions and recommendations, or advice. 

The best Advice is to look at the mail piece.  That is the deciding factor on what codes you mail and what codes you do not mail.  For example if you are mailing bills then you should mail all of the mail pieces.  The letter may make it to the person who in turn may pay you.  If you are mailing a very inexpensive flyer then again mail almost all of the mail pieces.  If you are mailing an expensive catalog then start to trim back the error codes that you are sending out.  Here is the order that I would use to remove pieces from the mailing list. 

E601 Not a valid delivery point.  The DPV data is telling you that this address does not exist so most likely these pieces will not be delivered.

E600 According to the USPS no delivery to this address is possible.  The address is in the directories but is tagged as undeliverable by the USPS 

These are about the only ones I would not mail to.  However if I was short of pieces for the mailing then I would look at the rest of the codes on a case by case basis.  A list of the Error codes can be found in the help topics for each of the different SAP software packages.

      We ran into an interesting situation with E601 codes.  Some of the addresses coded E601 were actually actual deliverable locations. They were in a new development with newly named streets.  The addresses were not included in the latest database. Since the mailing was from the organization that built the development, it took some explaining to them as to what happened.  For the next mailings for them we had to be sure these addresses were mailed even though they were E601.

      We mail to addresses with E601 codes because we've also found that it's simply a matter of the USPS directories being incorrect or not updated.  At times, we have to ask our customers to contact the USPS to correct the situation. Since IMB, it seems more error-coded addresses are not getting delivered where, in the past, most got delivered.
