Although the substantive content is largely similar, some states have made structural modifications to conform to local customs. For example, Louisiana jurisprudence refers to the major subdivisions of the UCC as "chapters" instead of articles, since the term "articles" is used in that state to refer to provisions of the Louisiana Civil Code. Arkansas has a similar arrangement as the term "article" in that state's law generally refers to a subdivision of the Arkansas Constitution. In California, they are titled "divisions" instead of articles, because in California, articles are a third- or fourth-level subdivision of a code, while divisions or parts are always the first-level subdivision. Also, California does not allow the use of hyphens in section numbers because they are reserved for referring to ranges of sections; therefore, the hyphens used in the official UCC section numbers are dropped in the California implementation.
