Example: serial 098600840P decodes to September 1986.

Trap: 098600840P = Sept 1986; some serials end with a letter. Century ambiguous; shape collides with Rheem MMYY.

Where the data plate is on a water heater

The rating plate is a large label on the side of the tank near the top or beside the control. The serial is printed on it, often beside the model number and the ANSI standard line.

General guidance, not brand-specific: the owner's manual or the installer can point to the exact spot. See the data plate guide.

For scale only: the InterNACHI Standard Estimated Life Expectancy Chart for Homes lists Water Heater (conventional) at 6 to 12 years of expected service (nachi.org). That chart is a guideline, not a prediction for your unit.

Official lookup

No online serial lookup was found for Vaughn in our research. The manufacturer's customer service line, the installer's invoice, or a printed date on the plate are the remaining authorities.
