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.
