WordPress plug-in that assigns a unique reference id and attach it to every post

I’m working for a realty brokerage firm who have a requirement of generating a unique reference ID and attaches it to every property/post listed by individual agents. Such that when a customer likes a property they can only refer to it by the unique reference ID rather than the entire property name which could possibly lead to confusion. Is there an existing plug-in that does the same or any other beginner friendly way to do this on WordPress?
