Alphabetization

Terms are alphabetized letter by letter. This style is standard for most dictionaries. It continues across spaces or symbols such as hyphens, slashes, and periods that occur between words (e.g., five-digit ZIP Code, Delivery Bar Code Sorter/Output Subsystem, and U.S. Postal Service). In addition, terms with numerals are alphabetized as though spelled out (e.g., 5D for five-digit and 7:01 rule for seven zero one rule).
