Mexico Clave Unica De Registro De Poblacion View

MexicoClaveUnicaDeRegistroDePoblacionView is a headless read-only display of Mexico's Clave Única de Registro de Población (CURP), Mexico's government-issued personal identifier. It renders as a <span> with an accessible label. It is the read-only companion to MexicoClaveUnicaDeRegistroDePoblacionInput.

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

Implementation Notes

• Renders as <span>
• Format: Eighteen-character alphanumeric code built from name, date of birth, sex, and state of birth: first letter of the first surname plus its first internal vowel; first letter of the second surname (or X if none); first letter of the given name; six-digit date of birth (YYMMDD); H or M for sex (X for non-binary); a two-letter state code (NE for those born abroad); a consonant from each surname and the given name; then two further disambiguating characters. No trailing check digit.
• Provides accessible name via the label prop
• Companion to MexicoClaveUnicaDeRegistroDePoblacionInput

Props

• value: string (default: "") — the identifier to display
• label: string (required) — accessible label via aria-label
• ...restProps: any — additional HTML attributes spread onto the <span>

Usage

  <SummaryListItem term="Clave Única de Registro de Población (CURP)">

  </SummaryListItem>
</SummaryList>

When to Use
