Why this rule existsrationale

Somebody typing a mandatory number needs to know at that moment what it will be used for — a number given for a delivery call is not a number given for marketing texts, and the difference is decided by what was written beside the box. This is the disclosure half of the required-field problem: even a form that legitimately needs the number owes the consumer that sentence.

How to fix itremediation

Put a one-line disclaimer directly under the phone input saying what the number is for and whether texts are part of it. Done when the sentence sits within the field's own block rather than in a disclosure lower down the page.

A compliant exampleexample

Mobile number (required — we text delivery updates to this number). Marketing texts are separate and optional; see the box below.

Common mistakespitfalls

  • A disclaimer that appears only after the field is focused or filled is not present at the moment the consumer decides to type.

Notesnotes

Distinct from CON-043, which requires a separate optional CONTROL where the number is mandatory. This rule is about the TEXT beside the field, and a form can satisfy one and fail the other.
