Which of the following is NOT a valid method for giving personal notice as required by the insurance code?

The correct choice is the one that identifies a method that does not conform to the requirements for giving personal notice as stipulated by the insurance code. Personal notice, in the context of insurance, generally requires direct communication with the individual involved, ensuring that the party receives the information personally.

Notifying through a third party does not fulfill this requirement because it bypasses the direct engagement necessary for a personal notice. Personal notice is meant to ensure that the individual is fully aware of the information being communicated, and relying on a third party can lead to misunderstandings or a lack of receipt of the information by the intended party.

In contrast, the methods that involve mailing notice or using prepaid postage adhere to formal communication standards within the insurance framework, ensuring that the notice is sent directly to the individual. Additionally, delivering notice at the individual’s residence or principal place of business directly reaches the person involved, which aligns with the purpose of personal notice.
