Embedded Phone Number Undeclared

Why This Rejection Happens

Your sample messages include a phone number (e.g., "Call us at 555-0199"), but you did not check the "Embedded Phone Number" attribute in your campaign registration. Carriers treat phone numbers inside texts as "risk assets" because they are often used for spam redirection. You must declare them.

• Sample Message: "Thanks for subscribing! Call 800-555-1234 for help."
• Attribute "Embedded Phone Number" is Unchecked (False).
• Using a phone number that does not belong to the brand.

Root Cause Analysis

Primary Triggers

• Data Mismatch: The system automatically scans your samples. If it finds a 10-digit number pattern but the "Embedded Phone" flag is off, it rejects the campaign.
• Spam Filter: Scammers often use embedded numbers to bypass link filters. Declaring the attribute subjects the campaign to slightly higher scrutiny but allows it to pass.

Step-by-Step Remediation

Review Samples

Look at your 3 sample messages. Do any of them contain a phone number?

Update Attribute

If yes, edit the campaign and check the "Embedded Phone Number" box. If no, remove the phone number from the sample text to match the "False" attribute setting.

Pre-Resubmission Checklist

• My attribute selection matches my sample content.
• If I embedded a number, it belongs to the brand.

What reviewers check for code 30889

Code 30889 is reported as "Embedded Phone Number Undeclared". If any message contains a phone number other than the sending number, the campaign must declare the embedded phone number attribute. Reviewers compare samples with attributes; a number in a sample without the attribute causes this code, and undeclared numbers in production can trigger filtering.

Where code 30889 comes from

Code 30889 is one of the brand and campaign registration errors Twilio returns in its 30xxx error range when vetting fails. Other CSPs report the same underlying problem under their own reason codes, so the remediation below applies on any platform. It has a documented fix that usually needs one targeted correction and a resubmission.

Fix and verify before resubmitting

1. Search samples and templates for phone numbers.
2. Enable the embedded phone number attribute in the campaign.
3. Make sure embedded numbers belong to the brand (support, office or booking lines).
4. Format numbers consistently.
5. Resubmit with the attribute set.
6. Resubmit with a note that references code 30889 (Embedded Phone Number Undeclared) and lists each change made.

Sample resubmission note

Many CSPs let you add a note for the reviewer when you resubmit. A short, specific note shows what changed and speeds up the second review. Example for Northline Heating & Air:

Northline Heating & Air corrected the deficiency reported as code 30889 (Embedded Phone Number Undeclared). Changes made: search samples and templates for phone numbers; enable the embedded phone number attribute in the campaign; make sure embedded numbers belong to the brand (support, office or booking lines). All URLs, keywords and auto-replies were re-tested from an external network before this resubmission, and the campaign text now matches the live opt-in exactly.

Common mistakes that keep code 30889 coming back

• Including a support number in the HELP reply but not declaring the attribute.
• Using a third party's number in messages.
• Declaring the attribute but leaving numbers out of the samples.

Frequently asked questions about code 30889

Reviewers may treat it as one. Declaring the attribute is the safe choice when any message contains a number.

Is the sending number itself an embedded number?

No. Only additional numbers inside the message body count.
