When you are charged for shipping labels
USPS Ship labels are not charged at the time of creation. Instead, charges are processed after the labels are manifested, either by you or automatically by USPS.
Here’s how the timing works:
| Label Status | When It’s Charged | Details |
|---|---|---|
| ✅ Manifested before 6:00pm EST | Same day (between 5:00pm – 7:00pm CST) | You’ll see these charges in the Transaction Details Report the same day. |
| ❌ Not manifested, but SCAN form submitted | Same day (between 5:00pm – 7:00pm CST) | Submitting an End of Day SCAN form before 5:00pm CST also counts as manifesting. |
| ❌ Not manifested or SCAN form submitted | Next day (between 5:00pm – 7:00pm CST) | USPS auto-manifests the label at midnight CST and charges it the next day. |
Example:
- If you create labels on Monday at 3:00pm CST and manifest them by 4:45pm CST, they’ll be charged Monday evening.
- If you forget to manifest them, USPS will auto-process them at midnight CST, and the charges will appear Tuesday evening.
