How would insurance companies keep track of which homes had purchased insurance in the early days in America?

In the early days of America, insurance companies utilized fire marks as a primary means of indicating which homes were insured. A fire mark was a distinctive plaque that was affixed to the exterior of an insured building, typically near the front door or visible on the façade. This practice served a couple of important functions.

Firstly, it provided a visual cue to firefighters and passersby; when responding to a fire, firefighters could quickly identify which buildings were insured and thus prioritize their efforts accordingly. The presence of a fire mark indicated that the property owner had taken out a policy covering potential fire damage, and it communicated to fire crews the need for a specific response to protect that property.

Secondly, fire marks contributed to the broader insurance system and its trustworthiness. This system worked well in a time when record-keeping was less sophisticated; the physical mark on the building served as a straightforward symbol of the financial backing provided by the insurance company. Consequently, it reinforced the concept of risk management and the importance of fire safety in a rapidly urbanizing society.

The other options, while creative, did not serve the practical and effective purpose that fire marks did in communicating insurance status to both homeowners and firefighters.
