Identifying the Symptom: Invalid Phone Number Error

When integrating Stytch into your application, you might encounter an 'Invalid Phone Number' error. This error typically occurs during the user authentication process, preventing users from proceeding further.

What You Observe

Users attempting to authenticate via phone number may receive an error message indicating that the phone number is invalid. This can disrupt the user experience and hinder access to your application.

Exploring the Issue: Why the Error Occurs

The 'Invalid Phone Number' error arises when the phone number provided does not meet the expected format or is not supported by Stytch. This can happen due to incorrect formatting, unsupported country codes, or other discrepancies.

Common Causes

• Incorrect phone number format (e.g., missing country code).
• Unsupported phone number type or region.
• Typographical errors in the phone number input.

Steps to Resolve the Invalid Phone Number Error

To address this issue, follow these actionable steps to ensure the phone number is correctly formatted and supported by Stytch.

Step 1: Verify Phone Number Format

Ensure that the phone number is in the correct international format. For example, a US phone number should be formatted as +1XXXXXXXXXX.

Step 2: Check Supported Regions

Consult the Stytch documentation to verify that the phone number's region is supported. If the region is unsupported, consider alternative authentication methods.
