Human rights groups and families of the missing expressed alarm and urged the government to urgently carry out more effective searches and investigations.
"It's incredible that disappearances are still on the rise," said Virginia Garay, whose son vanished in 2018 in the Pacific coast state of Nayarit.
Garay now works with other families in a group called Warriors Searching for Our Treasures to try to track down missing loved ones, one of many civil society groups doing such work.
"The government is not doing enough to find them," she said.
Cases of disappearances have spiked since 2007, after former President Felipe Calderon sent the army into the streets to fight drug traffickers, unleashing a wave of violence that the current administration is still grappling with.
Here is a statement that reads "Until we find them".
A report last week revealed that cases of missing migrants in Mexico jumped nearly fourfold in 2021 from 2020.
