Typically, the tracking number is provided immediately after a successful order placement or directly by the sender at postal offices. However, you might not know which carrier the tracking number belongs to, making it challenging to trace your package.

I. What is a Tracking Number?
A tracking number (also known as an order number) is a unique sequence of numbers or letters assigned by shipping carriers to monitor and locate a package as it moves from the seller to the buyer. In simple terms, it is a code generated by the delivery service to verify and identify the shipment.
The tracking number is typically printed on the shipping label and attached to the package. It is generated by the delivery service once the shipment is successfully created on their website, app, or at the postal office. This number plays a crucial role in the shipping and delivery process.
