Frequently asked questions — KDDI
Yes, the verification system doesn’t know the number is shared. However, because the inbox is public, anybody could see that code. Only use KDDI numbers for throwaway accounts.
Each carrier has different infrastructure and spam prevention policies. KDDI numbers are monitored here alongside others so you can pick whichever works best for your specific verification need.
Active numbers typically show recent incoming messages. If a KDDI number’s page shows no activity for an extended period, it may be dormant. We recommend choosing a number with recent timestamps.
Yes, use the search box on our site. You can enter any KDDI number to check its current status, read its public SMS, or see its reverse lookup report.
If you believe your personal number is incorrectly indexed as a public KDDI number, contact our support team immediately. We can verify and remove it from the directory.
Yes, using shared public numbers for non‑commercial, legitimate verifications is legal. However, using them for fraud, harassment, or violating a service’s terms of service is not permitted.
The count fluctuates because numbers are constantly being added and removed. When a KDDI number stops receiving SMS or expires, it is replaced by a new one, keeping the pool fresh and reliable.
