Campaign ID Structure/Examples

We are looking to build out our Campaign ID's and we have a mix between Campaigns that are based on fiscal year, some that are for multiple years, and others that will be used year over year.

Our desire is to have a code convention that makes it easy for searching as the codes grow over the years.  So for fiscal year Campaigns we are thinking something like this: 2 digits for fiscal year, 4 digits for identifier, and G or R for general or restricted.  That structure doesn't work out for the multiple year campaigns or campaigns that are not confined to a time-frame.


Any recommendations to make it easy for users to search for campaigns during gift entry and doing analytics?
