Hello Priyanka

Unique means that regardless how many ID's you generate you will never get a duplicate ID.

There also is another function module you can use to achieve this. It provides ID's of different length:


You usually use this function to generate ID's when you have to make sure that there won't be any duplicates.

Hope that helps,
