if you just wanted a number, could use something like:
Math.floor(Math.random() * 1000000) 

You could set a property to be the counter and increment from there. There would technically be a race condition where two threads could read the same value and come up with the same result but it would be very difficult to produce that issue.

or use a GlideRecord lookup for existing non-employee profiles to get the max value and increment that

GlideRecord setValue

setValue(String name, Object value) Sets the specified field to the specified value. Normally a script would do a direct assignment, for example,  gr.category = value . However, if in a script the element name is a variable, then  gr.setValue(elementName, value)  can be used. When setting a value, ensure the data type of the field matches the data type of the value you enter. This method cannot be used on journal fields. If the value parameter is null, the record is not updated, and an error is not thrown!/api_doc?v=madrid&id=r_GlideRecord-setValue_String_Object
