What is Route and Green Package Protection?

Route's Green Package Protection is a package projection solution that helps you cover your order in the event that your order gets lost, stolen, or damaged while in transit while also protecting the planet. We know it is frustrating to have something happen to your order, so we've partnered with Route to offer added assurance that you're supported, no matter what. Green Package Protection can be added during checkout.

Every time you add Green Package Protection to your order, Route donates to support an agroforestry initiative that removes COfrom the air and promotes a flourshing ecosystem.

You can also utilize the Route App to visually track all of your online orders in one place and easily file a claim with their team. Whether you're tracking via the Route App or online, Route's real-time shipping updates keep you in the loop throughout every part of your delivery. Haven't downloaded the app yet? Download here.

How Does Route Process Refunds or Reorders?

Refunds: When refunding an item, Route covers the subtotal, shipping, and taxes.

Stolen (or any package that has been marked as delivered but your customer cannot locate)

  • Your customers have up to 30 days from when the package was marked as delivered to file a claim. Claims will not be approved before 5 days after the package has been marked as delivered giving the carrier time to "actually" drop off the package or for neighbors to return it in the case that it was delivered to the wrong address.

Stuck in Transit (Lost)

  • Your customers have up to 30 days to file a claim.
  • Domestic packages are not considered lost until after the 7th day without a tracking update.
  • International packages are not considered lost until after the 20th day without a tracking update.

Damaged
