How about we add a new feature so that we can differentiate between different customers and vendors using there unique ID. We are able to do this somehow using the custom fields but is really not helpful for existing customers.

So if we add an additional feature that would help us find the customers/vendors using unique ID that would show up in customer portal as well as the contacts to identify that particular user or vendor with different prefixes i.e. a different prefix for a vendor and a different prefix for a customer should add a great value.
