4 digit Ids
All ids should be segregated into 2 digit chunks so it's easy to recite/recall. With respect to IT systems, when the unique id surpasses the 4 digit mark, the current set should be migrated to a archive branch and the main active set/trunk should be truncated for a new id namespace. Of course, this can't be done for a customer id base (assuming your company has millions of names), so 2 digit chunks should be the format.
