# Phone

Phone numbers remain one of the most direct and effective communication channels—when they're accurate and properly formatted. Delpha's **Phone Validator** helps you standardize, verify, and clean your phone data to ensure consistency across systems and better outreach performance.

Each phone entry is evaluated on three key aspects:

* **Completeness:** Detects whether a phone number is present and properly structured.
* **Validity:** Checks if the number follows the correct national or international format and isn't blacklisted or clearly invalid.
* **Consistency:** Compares the original input to its normalized international form.

By using optional context such as a **country** or **country code**, the system applies the right validation rules and returns a **standardized E.164-compliant number**. When no country is provided, Delpha applies smart defaults based on global dialing patterns.

Focused purely on validation and normalization, **Phone Validator** ensures your phone data stays clean, reliable, and ready for business use.

## Submit phone for finding and validation
