What are the three methods to initiate a domestic insurance claim?

The correct answer specifies three methods for initiating a domestic insurance claim: online, by mail, and at a postal retail unit.

Initiating a claim online allows customers to quickly submit their information without needing to visit a physical location, enhancing convenience and efficiency. The option to submit a claim by mail provides an alternative for those who may prefer to complete and send a physical form rather than using digital methods. Additionally, visiting a postal retail unit allows customers to receive in-person assistance, ensuring any questions or concerns regarding the claim process can be addressed gently.

These methods are standardized within USPS procedures to ensure that customers have flexible options based on their preferences and needs.
