A code (PIN) number is an integer value. That is, a whole number. In our case, the code size can be any value greater than zero (0) and less than 2,147,483,647.

NRC Codes Vs. Tenant Codes:
It is a good idea to use different length codes for NRC and Tenants. This will help prevent unintended duplication. If all Tenants have 8 digit code, then make the NRC's have 6 digit. If all Tenants have 6 digits, make NRC's have 8.
Length of Code:
The longer the code, the harder to randomly guess the code. However, too long of a code can be difficult for some people. Please judge the code length by your local demographics, and individual preferences.
