I've noticed that 17track (a shipping tracking service that allows you to see multiple shipment statuses from different services) hasn't been working well recently. It's very slow and rarely works without several refreshes. Is there an alternative out there? I really like being able to look at a single page and seeing all my various shipments together.
I find parcelsapp has the least problems with various tracking but you still have to open all tracked parcels separately.
Agreeing that Parcelsapp is a good alternative! It also seems to have a more update range of shipping services that it searches than 17Track. I've had it give me updates before from a new-ish courier service that 17Track didn't cover (they do now). My package had switched couriers for the last mile and 17Track just stopped updating while Parcelsapp was able to show me that the package had been handed over to that new-ish courier service. However, as mentioned above, you need to search each of your packages separately on Parcelsapp. Also it can take a while to load for me sometimes. (And like most tracking sites I've tried, it has trouble tracking packages shipped by SF Express. SF Express' own tracking site is still the best choice.)
I use International Package Tracking | Track Your Packages and Shipments Worldwide | Universal package tracking | 4Tracking and it's the best site so far.
