Underpaid Postage

Follow

Kidizen will make adjustments to accounts that purchase a label at a weight that is below the actual package weight. Under the USPS Automatic Package Verification Program, Kidizen is automatically charged for underpaid postage. We recognize that determining the cost of postage can often be confusing and that underpaid postage is not usually intentional. Here are some ways you can avoid underpaid postage:

  • Weigh your items after they are in their packaging. Packaging adds extra weight, especially boxes. Poly mailer bags will be the lightest option and only add a few ounces. 
  • Make sure your scale is accurate. This can be done by using the calibration feature or hand calibrating. 
  • Make sure to round up. For example, if your package weighs 8.1 ounces, you should purchase the 12-ounce label. 
  • Use non-carrier packaging. Priority packaging will incur a Priority shipping charge from USPS. 
  • Make sure not to use packaging from other carriers, such as USPS boxes. The only exception would be the USPS Flat Rate Padded Envelope which can be used with our Padded Flat Rate Envelope only. 

 

How adjustments will work:
If we receive a notification for underpaid postage, we’ll first check to make sure this claim is in line with the contents of your order and that the Post Office scan isn’t off. For instance, if you mailed a pair of infant shoes, these shouldn’t show up as 2 lbs when scanned. If your label does appear to be short the accurate postage, the overage will be taken out of your KidBucks account. If you do not have money to pay for the overage in your account, it will be taken out when you do and you will be notified at that time. Because you are not notified until we are able to charge your account, the charge may not come until months after you have sent the order.  

After 3 underpaid postage charges, a penalty fee of $2 will be added to each underpaid postage charge. 

 

Packages 5 pounds or over are subject to both weight AND volume limits.

Volume Limits

Packages are subject to BOTH weight and size (volume) restrictions so make sure to choose the appropriate size label that will cover both. 

Small: < 8 ounces (no dimmension requirement currently)

Medium: < 12 ounces (no dimmension requirement currently)

Large: < 16 ounces (no dimmension requirement currently)

Extra Large Label: < 5 Ibs and < 172 in³

XX-Large Label: < 10 Ibs and < 518 in³

Jumbo Label: < 20 Ibs and < 864 in³

 

Cubic inches can be calculated by multiplying length x height x width. For example, 12" x 10" x 2" = 240 cubic inches. You can also use this calculator

Underpaid volume overages are a direct pass through of the USPS charge. Make sure you are taking extra care when measuring as these charges can get expensive. 

 

Maximum sizes

  • The maximum combined length and circumference of any parcel is 108” (this includes outer packaging).
    The circumference is width plus height multiplied by two, so combined length and circumference = L + 2x(W+H).
  •  
  • The maximum length of any side is 47"
  •  
  • The largest standard-sized parcel is 20 lb and up to 864 in³

 

 

 

If you think you were charged underpaid postage incorrectly, you can dispute the charge through USPS by contacting BCNVB0@usps.gov and DELIVERY.CONFIRMATION@usps.gov with:

  • Your tracking number
  • Your contact information (First and last name, phone number, and email address)
  • The reason for the dispute

Typical turnaround time is 2-5 business days but it may take up to 15 days. Kidizen will receive an email when a dispute is opened and a second when the dispute is approved or denied.
