Color Coding and File Folders
Terminal Digit Filing
Terminal digit is a means of filing consecutively numbered folders in a different sequence. The file number is divided into groups of two digits called primary, secondary, and tertiary terminals. For example, take the file number 607458. The number is broken into groups of two-60-74-58-with the group 58 becoming the primary terminal, 74 the secondary terminal, and 60 the tertiary terminal. This method comes closest to a perfect distribution of records. Two consecutively numbered folders would be located in different sections in the system. Responsibilities can be assigned to personnel by terminals thus eliminating traffic jams. Little backshifting is required when blocks of numbers are retired as they are evenly distributed throughout the system. The same exists for new numbers assigned. It is also easier to recall a number broken into groups rather than remembering a straight six-digit number.
