How many bundles are required for sorting a non-machinable USPS Marketing Mail letter sized mailing weighing 16 pieces to zip code 85008, 9 pieces to zip code 85213, 5 pieces to zip code 85201, and 13 pieces to zip code 85220?

To determine the number of bundles required for sorting a non-machinable USPS Marketing Mail letter sized mailing, it's essential to understand the bundling process based on ZIP codes. Each unique ZIP code typically requires a separate bundle due to the sorting and delivery process used by USPS.

In this scenario, the mailing consists of:

• 16 pieces to ZIP code 85008

• 9 pieces to ZIP code 85213

• 5 pieces to ZIP code 85201

• 13 pieces to ZIP code 85220

Each distinct ZIP code represents a different destination, and since non-machinable mail must be handled separately, it’s necessary to create one bundle for each of the four ZIP codes involved. Therefore, you will create bundles for:

1. ZIP code 85008

2. ZIP code 85213

3. ZIP code 85201

4. ZIP code 85220

This results in a total of four bundles being required. The answer falls in line with the bundling rules set forth by USPS for non-machinable marketing mail, confirming that four bundles are indeed necessary to properly sort and deliver the letters to their respective destinations.
