# Message Codes

Introduction

Error and information messages that are written in continuous text are much easier for human beings to read and understand, but it is considerably more difficult to have them processed by automated systems. Any change made in the texts of the messages inevitably causes extensive adjustments to the systems operated by all DENIC members. To relieve that situation, DENIC uses 11-character alphanumeric codes for the messages returned by its systems.

In this section, we describe the syntax and the structure of the 11-character alphanumeric message codes issued by the DENIC registration systems. This type of coding is applied to all newly created messages and is in consistent use in the registration system (for both .de and ENUM).
