Simply click on the above link to the Brazilian Postal Tracking service (also available in english) and punch in the registry number we sent you. (Also you can find this number on the registry voucher under "OBJETO" )
Then the site informs you about the stages which the parcel took and when it left Brazil to your Country.
You can trace the parcel only on brazilian territory. When it left Brazil, it is unvisible due to different international tracking number systems, but it is then already in your country and delivery depends then only of your Postal and Customs service.
Please remind that a severe customs check can delay delivery up to 20 Working days.
