I'm going by what the documentation says: that the CSR's know what the customer's id number is. The only validation I have is to check and make sure that the id is 8 digits long, not a digit more or less. I don't think we need to question whether 00000001 is valid or not, because we are assuming they know what it is. However, I would check for the 8 digit length though. Just my advice.

I know my documentation says the customer ID is an 8 digit number. Is the 8 digits a hard requirement? or can it be less than 8 digits? something like 123.

I would interpret it as 8 digits long. Not 3 or 4. But that's just my opinion.

Hi Lucy,

which assignment are you doing? Does your instruction say you have to deal with the customer number? As for my assignment, the instruction does tell how many digits the customer number has, but it clearly tells you that you don't have to deal with this field, the care should be taken by the customers themselves. My understanding is, I could just leave enough space for the digits somewhere when needed, but no verification in my program. How do others think?

Regards,
Ellen

Hi everyone,

Regarding the size of the customer ID, you might want to look at the topic "Questions about contractors answered by sun".

great thanks. Well, looks like smaller numbers are ok - however, I have already done validation to check is 8 digits (and an integer), so will leave that and justify my choice in the documentation.
