Terms of Service

Acceptance

By using BulkNumberChecker, you agree to these terms. If you do not agree, do not use the service.

Credits & pricing

Signing in with Google grants your account 100 free credits, one-time. Beyond that, you can buy credits at $5 per 1,000, in any quantity. Credits never expire and are not a subscription — there is no recurring charge. 1 successfully checked phone number (via the web app or the API) costs 1 credit; numbers that fail to parse are not charged.

Payments

Payments are processed by Lemon Squeezy, our Merchant of Record. Lemon Squeezy handles billing, taxes, and payment security for all credit purchases; we do not collect or store your card details.

Refunds

If a submitted batch fails entirely before processing (for example, our WhatsApp session was unavailable), the credits charged for that batch are automatically refunded to your account. For any other billing issue, contact support through the form available in the app and we will review it case by case.

Acceptable use

• Do not submit numbers you do not have a lawful basis to check.
• Do not use the service to harass, spam, or defraud individuals.
• Do not attempt to abuse rate limits, share API keys, or bypass security measures.
• Comply with the privacy and marketing laws of your jurisdiction.

Disclaimer

BulkNumberChecker is provided as-is. We do not guarantee 100% accuracy. WhatsApp registration status can change at any time. Results are a snapshot, not a guarantee of deliverability.

Trademark notice

BulkNumberChecker is not affiliated with, endorsed by, or sponsored by WhatsApp LLC or Meta Platforms, Inc. WhatsApp is a trademark of its respective owner.

Liability

To the maximum extent permitted by law, BulkNumberChecker is not liable for any indirect, incidental, or consequential damages arising from the use of the service.
