## Why this rule exists

Numbers reach the sending list from every form on the site — contact, booking, quote, donation, callback — and the ones collected on unlabelled forms carry no consent at all. Reviewers crawl for phone inputs rather than trusting the registered URL, which makes this the single highest-yield finding in the corpus, and the one brands are most surprised by: they fixed the signup page and never thought of the contact form.

## How to fix it

Inventory every form on the site that takes a phone number, and add the consent control and disclosure to each one — or remove the phone field from the forms that do not need it, which is usually the cheaper fix. Done when a site-wide search for phone inputs returns nothing without a consent block beside it.

## Common mistakes

- Forms embedded from a booking or scheduling vendor are the ones most often missed, because nobody thinks of them as pages on the site.

## Notes

Needs a whole-site crawl for phone inputs. The current crawler fetches the registered page only, so this rule will return UNCLEAR in production until that lands — recorded here rather than omitted, because the requirement is real and the gap is the crawler's.
