Changing the way we manage underpaid postage

Learn how the changes to parcel size verification could affect you.

What's changing?

Our process to identify and charge under-declared parcels sent via MyPost Business is changing. From 4 October 2021, our parcel processing machines will automatically detect if there are any differences between what was paid for and what we scanned.

You’ll be notified if any discrepancies are found, resulting in underpaid postage which will be calculated using your applicable MyPost Business sending rates.

To prevent any underpaid postage being added to your MyPost Business account, measure and weigh your items accurately when creating your postage label.

How it works

Detect

Our parcel processing machines will automatically detect if the parcel’s weight and dimensions are different to what was declared and paid for on the label.

Notify

If any items have underpaid postage, we'll add the difference to your MyPost Business account.

Review & pay

The item will be delivered and you'll have 14 days to pay the outstanding amount.

Measuring your parcels

Learn how to accurately measure your parcel’s weight and dimensions and calculate the correct postage.

How postage is calculated

We use both a parcel's weight and its dimensions to determine how much space it will take up in our vehicles. When you enter the correct weight and parcel dimensions, it helps us ensure your parcel moves through our network as efficiently as possible, and that you’re charged correctly.

If you’re using our If It Packs, It Posts satchels or boxes, we’ll check that the measurements correspond to the size of that particular packaging, and the item weighs under 5kgs.
