Mexico Clave Unica De Registro De Poblacion Input

MexicoClaveUnicaDeRegistroDePoblacionInput is a headless input for entering Mexico's Clave Única de Registro de Población (CURP), Mexico's government-issued personal identifier. It renders as <input type="text"> with autocomplete="off" to protect sensitive identifiers. It is the editable companion to MexicoClaveUnicaDeRegistroDePoblacionView.

Status: beta — implemented and unit-tested in all seven frameworks; not yet exercised in a composed flow.

No trailing check digit.
• autocomplete="off" to protect sensitive identifiers
• Supports two-way binding on the value prop
