How do I track a Slovenia Post registered letter?
Registered mail (priporočena pošiljka) is tracked end to end and requires a signature on delivery, so its number scans in the tracker like a parcel. Registered numbers usually start with an "R" prefix in the S10 format (for example, RR123456789SI). Enter it on this page to see acceptance, transit, and delivery scans.
