SMPTE 301:
quote: Head leader (see figure 1) 5.1 Protective section (head) The protective section of the leader shall consist of a minimum of 8 linear feet (2.44 m) of transparent or raw stock. When the protective leader has been reduced to a length of 6 linear feet (1.83 m), it shall be restored to its original length. Logos, trademarks, part titles, or other extraneous materials, if absolutely necessary, should be placed in this section.

The labs often use stickers with numbers and bar codes to help track prints and individual reels through lab operations. Usually put on at the wind-up end of the print processing machines. If you have a print problem, the information on this label can often pinpoint all the machines and people that handled the reel to aid in diagnosing the problem.
Note, Kodak's magenta-colored edgeprint serves the same function for Kodak's manufacturing process:

quote: A description of the identifying codes on tape, can label, and film appears under FILM IDENTIFICATION.
http://www.kodak.com/US/en/motion/support/h1/identification.shtml#unprocessed
quote: The twelve-digit code on the label in Figure 45 (5289-489-02101) identifies the film type (5289), the emulsion batch number (489), the roll number and the part of the roll (02101) from which this strip of KODAK VISION 800T Color Negative Film was cut. When an emulsion batch is put together, it is quite large -- too large to be coated onto only one roll of film base. Therefore, it is necessary to coat more than one roll, and all subsequent rolls are numbered in sequential order. So, in this case, the first three digits identify the roll number of this particular emulsion batch. The last two digits identify the roll part. If one roll is coated onto a 6000-foot master roll, each strip can be cut into many individual parts. As an example, the 6000 feet can be cut into three 2,000-foot rolls--part 1, 2, and 3.
