Last updated: March 25, 2026
1. Acceptance of Terms
By accessing or using the CheckThatPhone website ("Site") and API services ("Services"), you agree to be bound by these Terms of Use. If you do not agree, do not use the Services.
2. Description of Services
CheckThatPhone provides a phone number validation API for US and Canada numbers. The API is available through RapidAPI and returns data including line type, carrier, location, and connection status. The demo tool on this Site provides limited free lookups for evaluation purposes.
3. API Access and RapidAPI
API access is provided through RapidAPI. Your use of the API is subject to both these Terms and RapidAPI's terms of service. You are responsible for maintaining the security of your API keys and for all activity under your account.
4. Acceptable Use
You agree not to:
- Use the Services for any unlawful purpose or in violation of any applicable laws
- Use the Services to harass, stalk, or intimidate any person
- Attempt to gain unauthorized access to our systems or networks
- Reverse engineer, decompile, or disassemble any part of the Services
- Use automated means to scrape or collect data from the Site beyond authorized API usage
- Exceed the rate limits associated with your subscription plan
- Resell or redistribute API data without authorization
5. Data Accuracy
CheckThatPhone provides phone validation data on an "as-is" basis. While we strive for accuracy, we do not guarantee that all data returned by the API is complete, current, or error-free. You should not rely solely on our data for critical decisions without independent verification.
6. Rate Limits and Usage
The demo tool on this Site is rate-limited for fair use. API usage through RapidAPI is subject to the rate limits and quotas of your subscription plan. Exceeding these limits may result in throttled or blocked requests.
7. Intellectual Property
All content on the Site, including text, graphics, logos, and software, is the property of CheckThatPhone or its licensors. You may not copy, modify, or distribute Site content without written permission.
8. Limitation of Liability
To the maximum extent permitted by law, CheckThatPhone shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of the Services. Our total liability shall not exceed the amount you paid for the Services in the twelve months preceding the claim.
9. Indemnification
You agree to indemnify and hold harmless CheckThatPhone and its operators from any claims, damages, or expenses arising from your use of the Services or violation of these Terms.
10. Modifications
We may update these Terms at any time. Continued use of the Services after changes constitutes acceptance of the revised Terms. We will update the "Last updated" date at the top of this page.
11. Termination
We reserve the right to suspend or terminate your access to the Services at any time, with or without cause, and with or without notice.
12. Governing Law
These Terms are governed by the laws of the United States. Any disputes shall be resolved in the courts of competent jurisdiction.
