A shipping service may be used where the carrier delivering the package to you is not the initial carrier that was used to ship your package out. This is typically the case with domestic and international orders as the package gets handed over to your local carrier for final mile delivery.
With DHL: If your tracking shows that the package was handed over to the local carrier, this means the package has been handed over from DHL to your country’s local carrier service for final delivery (ex. USPS, Canada Post, La Poste, Royal Mail). If you see the package has been handed over to the local carrier, please locate the 'alternate tracking number' (this will be on the right hand side on your DHL tracking page) and input this number on your local carrier's website to continue tracking it.
