## Why this rule exists

The undeclared method is the one generating complaints, because it is the one nobody applied the disclosure checklist to. Businesses omit them without deciding to: the web form is what the registration form asks about, and the fact that the sales team also collects numbers at trade shows never comes up until a recipient asks where the number came from.

## How to fix it

Ask everyone who could add a number to the list how they do it — sales, support, retail, events, the website — and declare every route that turns up. Done when nobody in the business can name a way onto the list that is not in the submission.

## Provider rejection codes

| Provider | Code | Resubmission allowed |

## Check this yourself

**Has everyone who can add a number to this list been asked how they do it — and does every route they named appear in the submission?**

1. Canvass sales, support, retail, events and the website. The web form is what the registration form asks about; the trade-show clipboard never comes up.
2. Add every route that surfaces to the declared methods.
3. Done when nobody in the business can name a way onto the list that is not in the submission.

*What wrong looks like:* The undeclared method is the one generating complaints, because it is the one nobody applied the disclosure checklist to. A pass here means nobody has been asked, not that nothing was omitted.

## Notes

The mirror of CMP-062, and the half of the pair no payload can settle: a method absent from the submission is also absent from everything we can read. The user has to canvass their own team and add whatever surfaces; we cannot check the answer, so a PASS here means nobody has been asked rather than that nothing was omitted, and the product must say so when it reports one.
