Where 383 fits
Why 383 is special
Kosovo was assigned +383 in 2016; before that its networks were reached through Serbian, Monacan and Slovenian numbers. A calling code was among the practical questions its status left unresolved.

Binary

1 × 256 + 0 × 128 + 1 × 64 + 1 × 32 + 1 × 16 + 1 × 8 + 1 × 4 + 1 × 2 + 1 × 1 = 383

5 × 64 + 7 × 8 + 7 × 1 = 383
Hexadecimal

1 × 256 + 7 × 16 + f × 1 = 383
Read as powers of two: 256 + 64 + 32 + 16 + 8 + 4 + 2 + 1 = 383.
In historical numeral systems
Egyptian
3 coils of rope, 8 hobbles, 3 strokes
3 × 100 + 8 × 10 + 3 × 1 = 383. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
6 vertical wedges (sixties place), 2 corner wedges + 3 vertical wedges (units place)
6 × 60 + 23 = 383. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
tau, then pi, then gamma, marked as a numeral
tau-pi-gamma + keraia
tau + pi + gamma written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
shin, then pe, then gimel
shin-pe-gimel
shin (300) + pe (80) + gimel (3) = 383, written in descending order.
Maya
3 bars + 4 dots (upper, twenties place) over 3 dots (lower, units place)
19 × 20 + 3 = 383. Places stack vertically with the smallest at the bottom, so the upper group is worth twenty times the lower.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.
