Number Insight Standard

Effective February 4, 2027, Vonage will sunset Vonage Number Insights. To ensure uninterrupted support and to provide a more scalable and future-proof solution, we encourage you to migrate to our enhanced offering: Vonage Identity Insights API. The Vonage Identity Insights API consolidates multiple phone number-related datasets into a single, flexible API, allowing you to request real-time information about a phone number and retrieve any combination of insights - such as number formatting, carrier details, SIM Swap and Subscriber Match - in one call.

Please review the Number Insights Transition Guide, which provides detailed guidance on API differences, required changes, and best practices for a smooth transition.

The Number Insight Standard API provides all the information from the Number Insight Basic API together with the following additional data:

The line type (mobile/landline/virtual number/premium/toll-free)
The Mobile Country Code (MCC) and Mobile Network Code (MNC)
The name of the caller (USA only)

Use this information to determine the best type of communication for a number (SMS or voice) and block virtual numbers.

Before attempting to run the code examples, replace the variable placeholders:

Key	Description
`VONAGE_API_KEY`	Your Vonage API key (see it on your dashboard).
`VONAGE_API_SECRET`	Your Vonage API secret (also available on your dashboard).
`INSIGHT_NUMBER`	The number you want to retrieve insight information for.

Write the code

Add the following to ni-standard.sh:

curl "https://api.nexmo.com/ni/standard/json?api_key=$VONAGE_API_KEY&api_secret=$VONAGE_API_SECRET&number=$INSIGHT_NUMBER"
