In most cases, once you’ve received the shipping notification, that means your order has been picked and packed into a box with a shipping label created for that package.
It can take up to 10 hours for UPS to reflect the package in their system, and in rare instances, it may take up to 24 hours. Rest assured that if you've received the shipment notification, your package is likely on the move.
Passport (international) orders are picked up once per week, on Fridays, and may experience longer fulfillment times compared to US orders.
