Chile Rol Unico Nacional Input

ChileRolUnicoNacionalInput is a headless input for entering Chile's Rol Único Nacional (RUN), Chile's government-issued personal identifier. It renders as <input type="text"> with autocomplete="off" to protect sensitive identifiers. It is the editable companion to ChileRolUnicoNacionalView.

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

Implementation Notes

• Renders as <input type="text">
• Format: Seven or eight digits plus a trailing check character. The check character is computed with a Modulus-11 algorithm: each body digit, read right to left, is multiplied by a repeating weight sequence 2,3,4,5,6,7; the products are summed; the check value is 11 minus the sum's Modulus-11 remainder, where a result of 11 maps to 0 and a result of 10 maps to the letter K.
• autocomplete="off" to protect sensitive identifiers
• Supports two-way binding on the value prop
• Companion to ChileRolUnicoNacionalView

Props

• label: string (required) — accessible label via aria-label
• value: string (default: "") — bindable input value
• required: boolean (default: false) — form validation
• disabled: boolean (default: false) — disabled state
• ...restProps: any — additional HTML attributes spread onto the <input>

Usage

<Field label="Rol Único Nacional (RUN)" required>
  <ChileRolUnicoNacionalInput label="Rol Único Nacional (RUN)" value={value} required />
  <Hint>Seven or eight digits plus a trailing check character.

  <ErrorMessage>Please enter a valid Rol Único Nacional</ErrorMessage>
</Field>

ARIA

• aria-label={label} — provides accessible name

When to Use

• Use in forms collecting Chile's Rol Único Nacional (RUN).
• Use in administrative or national-id workflows where the identifier is required.

When Not to Use

• Do not use for displaying read-only identifiers — use chile-rol-unico-nacional-view instead.
• Do not use for general text input — use text-input instead.
• Do not use for other countries' identifiers — use the corresponding country-specific input.

Headless

This headless component ships zero CSS. The consumer provides all styling targeting the .chile-rol-unico-nacional-input class hook.

Testing

• Verify renders an <input> with the correct class and type="text"
• Verify aria-label is set from the label prop
• Verify autocomplete="off"
• Verify value binding works
