Identifying the Symptom: Invalid Country Code

When using the Vonage/Nexmo SMS API, you may encounter an error indicating an 'Invalid Country Code'. This error typically arises when a phone number with an unrecognized or incorrect country code is used in the API request.

What You Observe

In your application logs or API response, you might see an error message similar to: "Invalid Country Code". This indicates that the API could not process the request due to an issue with the phone number's country code.

Exploring the Issue: Why Does This Happen?

The 'Invalid Country Code' error occurs when the country code in the phone number is not recognized by the API. This can happen if the country code is missing, incorrect, or not supported by Vonage/Nexmo.

Common Causes

• Incorrectly formatted phone numbers.
• Use of outdated or unsupported country codes.
• Typographical errors in the country code.

Steps to Fix the Invalid Country Code Issue

To resolve this issue, follow these actionable steps:

Step 1: Verify the Country Code

Ensure that the country code is correct and formatted according to the international dialing standards. For example, the country code for the United States is +1.

Step 2: Update Your Application Code

Check your application code to ensure that the phone numbers are being constructed with the correct country code. Here is a sample code snippet for reference:

const phoneNumber = '+1234567890'; // Ensure the country code is correct

Step 3: Test with a Valid Number

Use a valid phone number with a known country code to test the API. This will help you determine if the issue is with the specific number or the API configuration.
