If you received an email from Google about "unacceptable phone numbers," you're not alone—and you need to act immediately.
On December 10, 2025, Google is implementing a major policy change that could automatically suspend thousands of advertising accounts based solely on the phone numbers associated with them.
📧 The Email Thousands of Advertisers Received:
Dear Advertiser,
On 10 December 2025, we will update the unacceptable phone number section of the Destination requirements policy to include a requirement indicating that phone numbers found to be associated with fraudulent activity or with a history of policy violations are unacceptable.
We will begin enforcing the policy update on 10 December 2025, with enforcement ramping up over approximately eight weeks.
Thank you for your cooperation.
This isn't a minor update—it's a fundamental shift in how Google tracks and enforces advertiser compliance across accounts, time periods, and even business changes. Your phone number is now a permanent part of your advertising identity.

- What "unacceptable phone numbers" actually means

What Are "Unacceptable Phone Numbers"? Google's New Definition
Google's new policy targets phone numbers with two specific characteristics:
❌ Category 1: Associated with Fraudulent Activity
Google's Definition: Phone numbers that have been identified as being used in scams, misleading promotions, or deceptive business practices.
What This Includes:
- Scam operations: Numbers previously used for fraudulent schemes, phishing, or consumer fraud
- Fake business listings: Phone numbers associated with non-existent or misleading businesses
- Lead generation fraud: Numbers connected to deceptive lead capture or bait-and-switch tactics
- Consumer complaints: Numbers with patterns of fraud reports to authorities or Google
- Chargeback patterns: Phone lines associated with high dispute rates or payment fraud
⚠️ The Problem: Even if YOU didn't commit fraud, if you acquired a phone number that was previously used for fraudulent purposes, YOUR account is at risk.
❌ Category 2: History of Policy Violations
Google's Definition: Phone numbers that have been associated with accounts that violated Google's advertising policies in the past.
What This Includes:
- Previously suspended accounts: Numbers from Google Ads or Merchant Center accounts that were banned
- Circumventing systems violations: Numbers used when creating new accounts after suspension
- Repeated policy violations: Numbers associated with multiple strikes or warnings
- Unacceptable business practices: Numbers tied to accounts banned for counterfeit goods, misrepresentation, etc.
- Payment issues: Numbers connected to accounts suspended for suspicious payment activity
⚠️ The Problem: Google is now creating a permanent "blacklist" of phone numbers. If your business phone was on a suspended account 5 years ago, it could still be flagged today.
Why Is Google Doing This Now?
📊 The Platform Abuse Crisis
Google's enforcement team has identified sophisticated fraud networks that:
- ✅ Create multiple accounts with different business names
- ✅ Use the SAME phone number across all fake businesses
- ✅ Get suspended, then immediately create new accounts
- ✅ Keep the same contact number to maintain continuity
- ✅ Evade detection by changing everything except the phone
The Result: Phone numbers have become the most reliable way to track repeat offenders across account changes, business name variations, and time periods.
Industry Impact: Remember, Google suspended 39.2 million advertiser accounts in 2024 (up from 12.7 million in 2023). This phone number policy is their next evolution in combating that explosion of fraud.
Are YOU at Risk? The Phone Number Audit Checklist
Google isn't providing a direct way to check if your number is flagged, but here are the warning signs and risk factors:
🚨 Immediate Red Flags (HIGH RISK)
You're at HIGH RISK if any of these apply:

If even ONE of these applies, take action immediately. Don't wait for enforcement to begin.

How to Conduct Your Phone Number Audit
🔍 Step-by-Step Audit Process

"01234 567890" - Check EVERY result that appears

Ensure your number appears ONLY for your legitimate business.
Step 3: Review Your Google Ads History

Step 4: Verify Business Registration

Step 5: Document Everything
- Screenshot all legitimate uses of your number

Immediate Action Plan: Protect Your Accounts NOW
Based on your risk level, here are your options:
Option 1: Get a New Phone Number (RECOMMENDED for High-Risk)
📞 Clean Slate Strategy
Best for:
- Previously suspended accounts
- Numbers with unknown history
- Recently acquired business phone numbers
- Multiple red flags from the audit
Implementation Timeline (Complete by Dec 1, 2025):
| Week | Action |
|---|---|
| Week 1 |
Acquire New Number: • Contact UK telecom provider (BT, Virgin, Vodafone, etc.) • Request NEW number (not recycled) • Ensure it's registered to your business name • Set up call forwarding from old to new number |
| Week 2 |
Update All Business Listings: • Google My Business • Google Ads account settings • Google Merchant Center • Website (all pages, header, footer, contact page) • Email signatures • Business cards and marketing materials |
| Week 3 |
Update Secondary Platforms: • Bing Places • Social media profiles (Facebook, LinkedIn, Twitter) • Industry directories • Invoices and accounting systems • Customer communication templates |
| Week 4 |
Verify & Monitor: • Google search new number (should show only your business) • Test call forwarding works correctly • Confirm Google Ads recognizes new number • Keep old number active with forwarding for 60-90 days |
💡 Pro Tip: Keep your old number active with call forwarding for 2-3 months to avoid losing customer calls during the transition. Update Google Ads immediately, but maintain accessibility for existing customers.
Option 2: Clean Up Your Existing Number (Lower-Risk Situations)
🧹 Reputation Cleanup Strategy
Best for:
- Numbers with minor historical associations
- Shared numbers within legitimate business groups
- Unclear risk level but no major red flags
- Established businesses with long-term number recognition
Action Steps (Complete ASAP):
-
Remove Unauthorized Associations:
- Contact directory sites to remove incorrect listings
- Report fake business profiles using your number
- Clean up spam/scam listings via Google's report tools
- Request removal from lead generation databases
-
Establish Clear Business Identity:
- Ensure consistent business name across ALL platforms
- Add Companies House number to listings

-
Document Legitimacy:

Proactive Google Communication:

Enforcement Timeline: What to Expect
📅 The 8-Week Rollout Plan
| Period | Enforcement Level | What Happens |
|---|---|---|
| Dec 10-17 | ⚠️ Soft Launch |
• Policy goes live • Most egregious violations flagged • Warnings issued to borderline cases • Grace period for compliance |
| Dec 18-31 | ⚠️ Early Enforcement |
• Clear violations result in suspensions • Automated systems begin pattern detection • First wave of enforcement actions • Appeals processed slowly due to volume |
| Jan 1-31 | 🚨 Ramp Up |
• Enforcement intensifies significantly • More phone numbers added to blacklist • Broader pattern recognition active • Fewer grace periods granted |

Frequently Asked Questions
Will Google notify me if my phone number is flagged?
Google has sent notification emails to SOME advertisers (like the one shown at the beginning of this article), but they won't proactively notify everyone. The absence of an email doesn't guarantee your number is safe. Many suspended accounts never receive advance warnings. It's best to proactively audit your phone numbers and ensure compliance before enforcement begins.
Can I appeal if my account gets suspended for phone number violations?
Yes, you can appeal, but prevention is infinitely easier than cure. Phone number suspensions are particularly difficult to overturn because Google views them as system-level violations (similar to circumventing systems). If suspended, you'll need to either change your phone number AND provide extensive documentation proving your business legitimacy, or prove conclusively that the phone number history was not your fault. Success rates for these appeals are significantly lower than standard policy violations.
What if I share a phone number with other legitimate businesses?
Shared phone numbers are increasingly risky under this policy. Google's systems prefer unique contact information for each business entity. Even if all businesses sharing the number are legitimate, if ONE of them gets suspended, the shared number could be flagged, affecting all businesses using it. Best practice: Get separate phone numbers for each distinct business, or ensure the shared number is only associated with compliant, related businesses under the same ownership with clear documentation of the relationship.
How can I check if my phone number has a violation history?
Google doesn't provide a direct lookup tool, but you can investigate through:
- Google Search: Search your number in quotes to see what businesses appear associated with it
- Business Directories: Check Yell.com, Google My Business, Bing Places for unauthorized listings
- Google Ads History: Review your account's policy manager for any historical warnings
- Telecom Provider: Ask about the number's previous owner (if you acquired it recently)
- Professional Audit: Compliance specialists can perform deeper historical analysis
Does this affect Google My Business and organic listings too?
While this policy specifically mentions Google Ads and Merchant Center, Google often applies similar standards across their entire ecosystem. Flagged phone numbers could potentially affect:
- Google My Business listing visibility
- Local search rankings
- YouTube channel monetization (if linked to same business)
- Google Play Store developer accounts
Maintaining clean, compliant contact information benefits ALL your Google services, not just advertising.
Is this policy update UK-specific or global?
This appears to be a global policy update affecting all Google Ads advertisers worldwide. The enforcement timeline and specific requirements may vary slightly by region, but the core policy about unacceptable phone numbers applies internationally. UK businesses should pay particular attention to:
- Proper +44 country code formatting
- Companies House registration matching
- UK GDPR compliance in how phone numbers are displayed and used
- UK consumer protection law adherence
Should I change my phone number even if I haven't received a warning?
Not necessarily. Use the risk assessment checklist in this article to determine your situation:
- HIGH RISK (change recommended): Previous suspensions, recently acquired number with unknown history, multiple red flags from audit
- MEDIUM RISK (cleanup recommended): Shared numbers, multiple business associations, moderate concerns from audit
- LOW RISK (monitoring recommended): Long-term number with clean history, no suspensions, passes all audit checks
When in doubt, get a professional risk assessment rather than guessing—the cost of being wrong is too high.
