What is one method to purchase insurance at USPS?

Purchasing insurance for mail services at USPS primarily involves direct interaction with postal services, and the most common method is at the retail counter. This is where customers can purchase various mail services, including insurance, by interacting with a postal employee who can assist with the process.

While ATMs may be used for various banking functions, they do not facilitate the purchase of postal products such as insurance. Similarly, online banking is not specifically designed to handle USPS transactions, nor does it provide a platform for purchasing postal insurance. Lastly, making a phone call may provide information about insurance options, but it does not allow for the purchase of insurance directly, as payment must typically be completed at the postal counter or through designated online services.

Thus, the retail counter stands out as an accessible and straightforward method for purchasing insurance, ensuring that customers can obtain the service they need with assistance available on-site.
