The Mayan Numerals block spans U+1D2E0–U+1D2FF, 32 codepoints in Plane 1 (Supplementary Multilingual Plane). 20 are assigned in Unicode 16.0; the other 12 are reserved for future characters.

All of its characters have the script value Common: they are shared across writing systems rather than tied to one.

By general category: 20 other numbers (No).

The first 20 arrived in Unicode 11.0 (2018).

Because it lies outside the BMP, every character here takes four bytes in UTF-8 and a surrogate pair in UTF-16.
