What is the process for troubleshooting number verification failures?

WhatsApp Business Platform (WABA) Number Verification and Messaging Limits

When onboarding a phone number to the WhatsApp Business Platform (WABA), you may encounter verification failures. In addition, new numbers start with a default daily messaging limit, which can be increased over time by maintaining quality and completing verification in Facebook Business Manager (FBM).

This guide covers both troubleshooting verification issues and understanding how to raise your messaging tiers.

Common Number Verification Failures

Issue	Likely Cause	How to Fix It
SMS or voice code not received	Phone line blocks international SMS/voice; wrong number format	Ensure correct country code, allow international calls, retry with "Call me" option
"Number already linked to another account"	Phone number is in use on WhatsApp Consumer/Business App	Delete the account from the app and retry, or use a fresh phone number
Verification rejected by Meta	FBM documents incomplete or inconsistent	Upload valid business docs (e.g., GST certificate, license) matching your display name
Repeated verification failures	Browser/cache issues or FBM account mismatch	Try incognito mode, clear cache, ensure you’re logged into the right FBM
Unsupported region or carrier restrictions	Certain regions/carriers block verification	Contact Meta Support for override, or use a different carrier/number

Steps to Raise Your WhatsApp Messaging Limit

Maintain a High Message Quality Score

Avoid spammy content, excessive broadcasts, or unapproved templates.
WhatsApp auto-monitors recipient feedback to adjust your quality rating.

Submit Business Verification in FBM

Go to business.facebook.com.
Upload required documents (business license, GST certificate, website).
Verification typically takes 1–3 business days, though it can take longer.

Monitor Tier Advancement

Once verified, Meta evaluates eligibility for higher tiers.
Check progress in FBM → WhatsApp Accounts → Phone Numbers.

Messaging Tier Progression

Tier	Daily Limit (Unique Customers/24h)	Requirement to Unlock
Tier 1	1,000	Default for all new verified numbers
Tier 2	10,000	Maintain good quality score for 2–3 days
Tier 3	100,000	Continue high quality; active usage over time
Tier 4	Unlimited	Verified business, strong quality, consistent engagement

Meta automatically upgrades tiers if your business meets quality and compliance requirements.

Additional Tips

Green Tick (OBA) verification is optional and requested separately after FBM verification.
Business verification ≠ Green Tick — they are distinct processes.
Even after verification, new accounts remain at 1K/day until performance justifies upgrades.

Need Help?

If your number continues to fail verification or your tier isn’t upgrading, contact MyOperator Support or raise a case with Meta Business Support via FBM.

Tip : Always use a dedicated number for WABA onboarding — avoid numbers previously tied to WhatsApp personal or Business App accounts to prevent verification conflicts.
