Security & Reliability
The Numverify integration provides secure phone number validation and lookup services through a REST API, ensuring that only authorized workflows access your phone number data. Relevance AI manages API operations (like GET, POST, PATCH, DELETE) seamlessly in the background—eliminating concerns about errors, formatting, or limits.
With built-in validation and type conversion, your phone number verification workflows run smoothly, even when data formats vary. This integration allows for global phone number validation, carrier detection, and location lookup, enhancing your data enrichment processes.
No training on your data
Your data remains private and is never utilized for model training purposes.
Security first
We never store anything we don’t need to. The inputs or outputs of your tools are never stored.

To get the most out of the Numverify + Relevance AI integration without writing code:
- Start with valid phone numbers: Ensure that the phone numbers you are validating are in a consistent format, including the country code.
- Utilize built-in validation: Leverage Numverify's API to automatically validate and enrich phone numbers as they are entered into your system.
- Connect securely: Make sure to use the correct OAuth credentials and API token to authenticate your requests.
- Test with sample data: Validate a few phone numbers first to ensure your integration is working correctly before processing larger datasets.
- Monitor API usage: Keep an eye on your API call limits and implement throttling to avoid hitting rate limits.
