DPD’s smartphone-friendly website has smashed the one million unique user milestone, with more than 2.5 million parcels tracked via the online service in its first six months of operation.

Since its launch in November 2011, which the parcels giant says was an industry-first, more than 55,000 deliveries have also been rearranged via the QR (quick response) codes printed on DPD calling cards.

Customers scan the code and are directed instantly to the specific web page allowing redelivery.

Dwain McDonald, DPD chief executive, says: "Home shoppers, in particular, are extremely technology savvy and expect information about their purchases at their fingertips, whenever and wherever they want it.

"Our mobile website is designed to meet these needs by ensuring customers can quickly and easily locate information about their delivery.”
