Dmm 601 mailability score

The DMM 601 Mailability Score!

The DMM 601 is a widely used mailability scoring system developed by the United States Postal Service (USPS). It's a numerical score that assesses the ease of mailing a package based on its size, shape, weight, and other factors.

Here's a breakdown of the DMM 601 Mailability Score:

Score Range: 0-601

Factors Considered:

1. Length (up to 36 inches)
2. Width (up to 12 inches)
3. Height (up to 12 inches)
4. Weight (in pounds)
5. Shape (e.g., rectangular, irregular, cylindrical)
6. Surface Area (in square inches)

Interpretation:

• 0-100: Not Mailable (e.g., oversized, irregular shapes)
• 101-200: Special Handling Required (e.g., fragile, oversized)
• 201-400: Standard Mailing (e.g., rectangular packages)
• 401-601: Priority Mailing (e.g., small, lightweight packages)

Example:

Let's say you have a package with the following dimensions:

• Length: 24 inches
• Width: 8 inches
• Height: 6 inches
• Weight: 5 pounds

Using the DMM 601 formula, you'd calculate the score as follows:

• Length: 24/36 = 0.67
• Width: 8/12 = 0.67
• Height: 6/12 = 0.50
• Weight: 5/1 = 5 (since weight is in pounds)
• Shape: assume rectangular (0.5)
• Surface Area: approximately 144 square inches (0.144)

Add up the scores: 0.67 + 0.67 + 0.50 + 5 + 0.5 + 0.144 = 407.21

Round down to the nearest whole number: 407

In this example, the package would have a DMM 601 Mailability Score of 407, which falls within the "Standard Mailing" range (201-400).

Keep in mind that this is a simplified example, and actual calculations may vary depending on the specific package dimensions and USPS regulations.
