SSN¶

The validation should only be executed for identified numbers.
The return string is called Normbyte and is two characters long. The Normbyte is there to encode validation and classification results.

Classification¶

As a requesting service, I want to get information about the state of the number if it is validated as correct, that I have more details about the product number.

The classification should only be executed for valid numbers.

The return string is called Normbyte and is max. two characters long. The Normbyte is there to encode validation and classification results.
