Hi,
Do you have a previous employee code, or are you going to create one for the first time? If you are setting it up for the first time, you can start with a 4-digit number. For example, EC1001, where EC represents the employee code. If you prefer to assign numbers only, you can do so as well, ranging from 1001 to 1027 (for 26 employees).
Alternatively, you can begin with the initials of your company's name followed by a 4-digit number. This approach may provide you with some ideas on how to proceed.
Thanks & Regards,
A Renu
