Some legacy identifiers come in fixed length fields, insufficient for contemporary usage. I know a company where some identifier should have been lengthened long ago, but that would impact a couple hundred systems (and by system I mean whole applications, front and back) - so they keep plodding on with what they have and yes, it is a drag on operations and it causes endless hacks.
