Orthographies for the languages of Mexico are currently being developed by the Instituto Nacional de Lenguas Indígenas (INALI). The pre-Columbian Maya civilization developed and used an intricate and fully functional writing system, which is the only Mesoamerican script that can be said to be almost fully deciphered. Earlier-established civilizations to the west and north of the Maya homelands that also had scripts recorded in surviving inscriptions include the Zapotec, Olmec, and the Zoque-speaking peoples of the southern Veracruz and western Chiapas area—but their scripts are as yet largely undeciphered.

Tres Zapotes and eventually Cerro de las Mesas were the largest Epi-Olmec
