What should CCAs know about package sizes and shipping costs?

The understanding that larger packages usually incur higher shipping fees is based on the shipping industry's standard pricing structure. Shipping costs are generally calculated using several factors, including size, weight, and distance. When a package exceeds certain dimensions or weight thresholds, it often results in a higher cost. This is because larger packages require more space and resources for handling and transportation.

Moreover, shipping carriers often have tiered pricing systems where costs incrementally increase with size and weight. As a result, it is essential for City Carrier Assistants (CCAs) to recognize that shipping fees are typically proportional to the size of the package being shipped. By knowing this, CCAs can better inform customers and help them select appropriate shipping options based on their needs and budget.

In contrast, other options misrepresent how shipping fees are structured. Larger packages do not generally have lower fees, costs are not solely distance-based, and it is incorrect to say all packages cost the same regardless of size or weight. Understanding the correlation between package size and shipping costs is crucial for CCAs in their role.
