Most tracking numbers tell you the carrier from their shape alone. Paste yours into the tracker above and we identify it for you, or use the quick rules and the full table below.

Why some numbers match more than one carrier
Many couriers use plain digits, so a 10, 11 or 12 digit number can belong to several companies. In that case we show the most likely carrier first and let you switch. The carrier name in your shipping email or on the receipt settles it.
