This model works quite well for world wide enterprises, but with a little of creativity you can make it easier and fit to small shops too:
2 characters to country: "US", "BR"azil, "SP"ain, "CA"nada) 3 characters to city: SPO = Sao Paulo, HOU = Houston, VAN = Vancouver 3 characters to function: MSG = Exchange, SQL, WEB, APP = Applications, PRT = Printing 3 numbers to unique ID: 001, 099, 133, 899 Ex: BRSPOMSG001 = Exchange server #1 at Sao Paulo, Brazil USHOUSQL002 = Database server #2 at Houston, US CAVANWEB099 = Web server # 99 at Vancouver, Canada SPMADAPP133 = Application server # 133 at Madrid, Spain Depending on the number of servers you believe will accommodate the next 5 years growth, you can use 3 or even 2 numbers to designate the unique ID. If you shop is country wide "only" you can use the first two letters to designate the state.
