Hey there, I have been scavenging information on the internet trying to find other people that are dealing with this. You are not alone. I was charged roughly $5000 in shipping adjustments last night, July 4th, around 7:30pm. I have been on chat with support both last night and today. So far, the only information I have learned is that they can confirm this will not affect future orders. Other than that, there is truly no information as to how this is happening, a timeline for when it will be fixed, or a timeline on when we will be returned our money. I also found 4-5 other people who are dealing with this via twitter. Some have lost a couple hundred dollars some have lost thousands since this began yesterday. Please reach out to me if you need to talk or discuss anything.
Topic summary
On July 4th around 7:30 PM, numerous Shopify merchants experienced a massive wave of fraudulent USPS shipping label adjustments, with charges ranging from hundreds to thousands of dollars. One seller reported over 30 adjustments totaling $700, while another was hit with approximately $5,000 in unexpected charges.
The Issue:
- Adjustments cited incorrect weight/dimensions, but merchants had intentionally rounded up weights to avoid such charges
- Many packages showed impossible weights (0.16 oz—less than an empty box)
- Charges of $22+ appeared on First Class packages where dimensional weight doesn’t apply
- Dimension discrepancies were fractions of an inch that wouldn’t affect pricing
Merchant Frustrations:
- Initial support responses were unhelpful, directing sellers to contact USPS or file claims themselves
- Shopify holds the merchant shipping account, making independent dispute filing ineffective
- Charges processed during regular billing cycles despite the acknowledged error
- Some merchants incurred overdraft fees and had to postpone sales/shipments
- Support estimated 12k-50k adjustments were impacted (potentially $1.1M+ in erroneous charges)
Resolution:
- Shopify eventually confirmed a USPS billing system error affecting July 4-5 shipments
- Refunds/credits were promised and began rolling out
- Merchants expressed anger over lack of transparency, delayed communication, and inadequate compensation for secondary damages (overdraft fees, lost sales)
- No claims filing with USPS required for affected merchants
