Cultural Tip
In Brazil the word ‘rastreio’ is more common in everyday speech, while in Portugal you’ll often hear ‘rastreamento’. Both are correct, but ‘rastreio’ sounds slightly more informal. Also, the English borrowing ‘online’ is widely accepted in both countries, though some formal texts may prefer ‘pela internet’ or ‘na web’. When speaking to older speakers, you might replace ‘online’ with ‘pela internet’ to sound more traditional.
