Why is my Pony Express tracking not updating?

A Pony Express tracking number that has stopped updating is usually still in transit between two scan points, held in customs, or waiting out a weekend or holiday. Pony Express suggests contacting support if a status has not changed for more than 48 hours. First recheck that you entered the full waybill number with no spaces, and for inbound cross-border orders try the origin carrier's number too, since the two can update on different schedules.
