Which of the following refers to the expanded access channels?

The correct choice highlights the variety of ways customers can access postal services beyond traditional locations. Specifically, referring to SSK (Self-Service Kiosk), ATMs, and methods like Stamps by Mail and USPS.COM illustrates how expanded access channels enhance convenience for users.

By incorporating digital and self-service options, this range of access points allows customers to engage with postal services in a manner that fits their individual needs and schedules, reducing reliance on in-person visits to Post Offices. This expansion is crucial in today's fast-paced, technology-driven environment, where customers often prefer to conduct transactions online or via self-service options for ease and efficiency. These channels also cater to diverse preferences, ensuring that all customers have the means to access necessary postal services regardless of their circumstances.
