Next to the DOT letters is an alpha/numeric serial number, commonly referred to as the DOT Code, with up to 12 digits
This code provides manufacturer detail and the last 5 numbers indicate the week and year that the tire was made
For example, "1501" indicates that the tire was manufactured during the 15th week of year 2001

Color code to indicate values of electronic components
An electronic color code or electronic colour code is used to indicate the values or ratings of electronic components, usually for resistors, but also for capacitors, inductors, diodes and others. A separate code, the 25-pair color code, is used to identify wires in some telecommunications cables. Different codes are used for wire leads on devices such as transformers or in building wiring.
Recycling codes are used to identify the materials
Code identifying material, for recycling
Recycling codes are used to identify the materials out of which the item is made, to facilitate easier recycling process. The presence on an item of a recycling code, a chasing arrows logo, or a resin code, is not an automatic indicator that a material is recyclable; it is an explanation of what the item is made of. Codes have been developed for batteries, biomatter/organic material, glass, metals, paper, and plastics. Various countries have adopted different codes. For example, the table below shows the polymer resin (plastic) codes. In the United States there are fewer, because ABS is placed with others in group 7.
