I have been using 17TRACK app to track my parcels for many years. I discovered this free service a long time ago when started buying from chinese stores like Wish and AliExpress and I use it also now for Vinted, Wallapop, Ebay and many other online stores and national (Italian) and international carriers. They usually guess the actual carrier from the tracking code but you can eventually set it manually. They also provide links to the actual carrier official web site for cross checking. Very useful to have your parcels from different carriers all tracked in a single place avoiding me to install and use dozens of apps. Note that they are not a shipping company and they are not responsible for delivering your parcels, they just relay shipping infos from hundreds of carriers worldwide, so don’t blame them if they get lost or the seller is a scam (so sad to read many bad reviews from people who can’t understand the difference between the actual carrier and a shipping tracking aggregator service). Good work 17TRACK 👍
