Track a package by visiting the shipping company's website and entering the relevant tracking number. Most package tracking numbers are between 10 and 20 digits long, and some may contain letters as well.
Tracking options typically require an additional fee when shipping packages via the U.S. Postal Service. Packages sent with UPS or FedEx automatically contain tracking numbers. Typically carriers update package status reports only once or twice per day, so the websites may not contain the most up-to-date information. Most shipping services offer the option of receiving status updates via email, which results in automatic notifications whenever the status of a package in transit has changed.
