What does a Ukrposhta tracking number look like?

International items use the UPU S10 format: two letters, nine digits, and a two-letter country code, for example RR123456789UA. Items posted in Ukraine end in UA, while inbound items end with the origin country's code such as CN or PL. Domestic shipments within Ukraine use a numeric-only barcode of around 13 digits with no letters.
