What is the process for troubleshooting number verification failures?

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.

đźš« 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

âś… Steps to Raise Your WhatsApp Messaging Limit

  1. Maintain a High Message Quality Score
    • Avoid spammy content, excessive broadcasts, or unapproved templates.
    • WhatsApp auto-monitors recipient feedback to adjust your quality rating.
  2. 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.
  3. Monitor Tier Advancement
    • Once verified, Meta evaluates eligibility for higher tiers.
    • Check progress in FBM → WhatsApp Accounts → Phone Numbers.

  • đź“Ś Even after verification, new accounts remain at 1K/day until performance justifies upgrades.

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.
