In mail processing, what is the primary role of quality control?

The primary role of quality control in mail processing is to ensure compliance with postal regulations. This includes checking that all mail items adhere to the standards set by postal authorities regarding size, weight, format, and labeling. Compliance is essential for the efficient operation of postal services, as it helps prevent delays, minimizes errors during processing, and ensures that all mail meets the safety and security criteria required for delivery.

While checking the weight of packages, guaranteeing timely delivery, and verifying financial transactions are important aspects of mail processing, they fall under broader operational tasks rather than being specifically tied to the quality control function. Quality control focuses on maintaining standards that uphold the integrity of the mail system and enhance customer satisfaction by ensuring that all mail meets necessary guidelines before it moves forward in the processing chain.
