According to a poster, the Banco Central del Uruguay introduced a new series F 200-peso note (B555) on 29 December 2016. This note is like preceding issues (B548), but new series, new date, new signatures, new printer imprint, and several significant changes to the security features, including denomination as registration device, holographic windowed security thread, translucent features, map of Uruguay in OVI, iridescent stripes, and intaglio marks for the sight impaired.
Reportedly the 100-peso note has also been revised.
