Parcel, Muambator and Aftership are some of the options for tracking international parcels. The apps also work with packages transported by the Post Office and send notifications to the cell phone, just informing the order tracking code.

Apps to track international orders
Most international orders are delivered via Correios, especially from stores such as Shein, Banggood, Gearbest, AliExpress, Wish and Shopee. If this is the case, you can use the Correios application itself, which may be the best option.

There are some advantages to using the Correios app. In addition to the notifications arriving faster than on third-party platforms, it is possible to automatically obtain all the tracking codes associated with your CPF. The customer can also ask to suspend a delivery and, in some cities, the app notifies you when the delivery person is very close to the destination.
Muambator
Created by Brazilian developers, Muambator is an excellent free option (with ads) for those who have many packages to be tracked. In addition to notifying you about the progress of your deliveries via push or email, the application allows you to organize the tracking codes with tags and categories.

Another advantage of Muambator is that all tracking codes are stored in the cloud and you can use multiple devices at the same time, including the desktop site. The service supports logistics operators such as Correios, China Post, Hong Kong Post, UPS and USPS.
aftership
Aftership is a simple tracking application, but that doesn’t stop it from being complete. In addition to supporting postcodes from Correios, the service also notifies international shipments from UPS, USPS, FedEx, DHL, as well as automatic code detection from Cainiao (AliExpress).

One advantage is that the app is completely free and ad-free. You can also use it on more than one device at the same time, thanks to the synchronization of registered packages.
Parcel
Parcel is one of the most complete alternatives for tracking international packages. In addition to international couriers, the application also supports carriers such as DHL, Jadlog, Loggi and TNT, as well as automatically recognizing Cainiao (AliExpress) codes.

The downside is that Parcel is only available for the iPhone. In addition, the free version does not notify tracking updates, and has a maximum tracking limit of up to three packages. The premium subscription costs BRL 14.90 per year.
17TRACK
17TRACK is another option for those who want to track international parcels. With support for more than 900 carriers, the application is free, has no ads and allows you to organize orders by categories.

How to track the purchase through the store’s website
If you don’t want to download any application, the alternative is to track the order through the online store’s website. Almost every e-commerce offers an area to detail the code and other tracking information for an order.
How is the international tracking code
If the order is delivered by Correios, the international tracking code is made up of two letters, nine numbers and two more letters, as AA123456789BB.
The first two letters correspond to the mode of transport used, while the last two letters represent the country of origin of the shipment.
Why can’t I track my order?
If the tracking doesn’t work, check directly with the store about the possibility of tracking the delivery or if the code is incorrect. Not every shipping method allows the order to be tracked over the internet.
If your order is sent by private carriers, check the store’s website for the best way to follow the delivery process.
Is every international purchase delivered by the Post Office?
Not every international purchase is delivered by the Post Office. Some stores use private carriers like UPS, DHL and FedEx.
There is no set delivery time, as it depends on the Post Office’s logistical processes and the shipping option chosen by the store — as it is a postal service, some orders have higher priority over others.
