Customer Name Ranges

This section contains an overview table of customer name ranges. This table shows:

·        the name lengths

·        a description of the standard naming conventions

The initial characters “Y” and “Z” are reserved for customers. The following recommendation applies to companies that develop at several locations within the group:

·        Z for a branch office

·        Y for the head office

If no group exists and you do not need to distinguish between branch and head office developments, you can use both reserved characters without restriction.

You can only use special characters in names if these are explicitly allowed.
