USPS® shipments
USPS shipments: In general, USPS® wants you to ship your package as close to the Ship date as you can. That said, when shipping USPS® packages, you generally shouldn't have any trouble as long as you're handing the package to the Postal Service within a few days of the date on the label.
Whether USPS accepts packages with an old ship date is at the discretion of the USPS employee, so be super nice about it 😉
UPS® shipments
UPS® shipments: UPS prefers that you use your labels as soon as possible after purchasing them. If UPS considers a label too old to use, there's a chance that the package will be routed to a UPS Overgoods location, which is a facility where UPS holds packages that are unable to be recovered 🙈
Overgoods locations only apply to UPS shipments, not USPS.
Old UPS labels should be recreated
Best practice for old UPS labels: If a UPS label has been sitting without being used, the best practice is to simply recreate it and pay for a new one!
Auto-refunds after 28 days: Keep in mind that our software automatically refunds labels after 28 days. If your UPS label is auto-refunded, you'll need to recreate that label and not use the original refunded label when shipping out your package 👍
Don't use refunded or duplicate UPS labels: If you use a refunded label or if you use a label more than once, that package will get sent to a UPS Overgoods location and will be unable to be recovered.
You can't edit a label once you buy it
Your Ship Date can't be changed: Unfortunately, once you’ve purchased a label there is no way to edit it. So, if you need to change the Ship Date, you will have to request a refund for the label and start over.
