What service do USPS Mobile retail units provide?

USPS Mobile retail units are specifically designed to provide convenient postal services at special events and holidays. These mobile units allow USPS to reach customers who might not have easy access to a traditional post office, thereby enhancing customer service and ensuring that postal services are available in diverse locations during peak times. By operating in places such as fairs, festivals, or busy shopping seasons, these units can effectively cater to a larger audience, facilitating activities such as mailing packages, purchasing stamps, and providing information about USPS services.

The other options, while relevant to USPS services, do not accurately describe the primary role of these mobile retail units. For instance, delivery tracking, shipping insurance, and business account management are more typically handled at conventional post office locations or through online services rather than through mobile units.
