Form Missing Phone Input Field
Why This Rejection Happens
The URL or screenshot you provided for your opt-in form shows a form that collects data (like Name or Email) but does not have a field to enter a phone number. You cannot collect SMS consent without collecting the phone number itself.
Common Triggers: Submitting a link to an email newsletter signup form, a generic "Contact Us" message box, or a form where the phone field is hidden by conditional logic.
Root Cause Analysis
Primary Triggers
- Wrong Link: You accidentally linked to your email subscription page instead of your SMS signup page.
- Hidden Field: The phone field only appears if the user selects "Contact me by phone," but the default view hides it. Vetting agents review the default state.
- Message Box Confusion: You assumed users would type their number in the "Message" body of a contact form. This is not a structured data field and is rejected.
Required Elements
| Element | Requirement | Why? |
|---|---|---|
| Input Field | Specific "Phone" or "Mobile" field | Structured data collection is required for automated systems. |
| Visibility | Visible on load | Agents must see it without guessing how to trigger it. |
| Labeling | Clear Label | User must know what data goes there. |
Step-by-Step Remediation
Check Your Form URL
Open the link you submitted. Look at the form. Is there a box specifically for "Phone Number"?
✓ Compliant Form
Fields: [Name] [Email] [Mobile Number] [Submit]
✗ Non-Compliant Form
Fields: [Name] [Email] [Subject] [Message] [Submit]
Add the Phone Field
If the field is missing, log in to your form builder (WordPress, HubSpot, etc.) and drag a "Phone" field onto the form. Make it Required if SMS is the primary purpose.
Update Your Submission
If you fixed the live site, just resubmit the same URL. If you provided a screenshot, take a new one showing the added field.
Carrier-Specific Requirements
T-Mobile
- Requires the phone number field to be clearly labeled. A field just labeled "Contact" is often rejected if it looks like an email field.
AT&T
- Will verify that the phone field is functional. If the form validates email format but not phone format, it may be flagged as a configuration error.

- The form has a dedicated input for "Phone" or "Mobile."
- The field is visible immediately when the page loads.
- The URL provided points to the corrected form.
- I have not simply relied on the "Message" box for numbers.
Common Mistakes to Avoid
❌ Newsletter Signups
The most frequent error is submitting a footer "Newsletter Signup" that asks for Email only. You cannot use an email signup for SMS consent.
❌ "Optional" Phone Fields
If the phone field is marked "Optional" but there is no checkbox to specifically opt-in for SMS, it's ambiguous. If the primary goal is SMS consent, the phone field should be required or tied to a clear checkbox.
Expected Timeline
This guidance provides general information about 10DLC compliance requirements. To collect a phone number for SMS marketing, you must provide a mechanism to input that number. This seems obvious, but technical errors often hide these fields. MyTCRPlus does not provide legal advisory services or regulatory representation.
