Advanced Mobile Number Verification is an HLR Lookup (Home Location Register) and risk analysis service that allows you to check the validity of a mobile number and verify specific information such as line status (e.g. disconnected, phone turned off), fraud score, spam risk, recent exposure to data breaches and associated geographic data.
Openapi also offers the Start service, designed for those who need access to a more limited set of data (number validity, current and past operator, geographic details).
The service is available worldwide and delivers results within seconds.
Mobile Number Information Request
REQUEST EXAMPLE
POST /mobile-advanced
To use the service, simply make a POST request to the /mobile-advanced endpoint, passing the mobile number to be verified as a parameter. The number must always include the international dialing code (e.g. +39) and must not contain any spaces between digits.
POST /mobile-advanced/+393391234567
The response usually takes just a few seconds, but if you wish to be notified when all the data is ready, you can configure a callback.
{
"callback": {
"url": "https://your-server.site/123232",
"custom": 123
}
}NOTE: When configuring the callback, it is mandatory to include a valid URL capable of handling POST requests. You can also populate the 'custom' field with any additional data you want to receive in the callback response.

The response includes over 25 pieces of information about the mobile number, including:
- id, required to retrieve request data later

}NOTE: When the response shows "N/A" (not available), it means the data is not available for that specific request.
If the request cannot be processed within the first 10 seconds, a partial response will be returned with status NEW and the ID to manage it asynchronously. The partial data includes the number analysed and formatted, the time the request was created and updated, and the ID associated with that request.
"data": {
"requestedNumber": "+393334567890",
"formattedNumber": "+393334567890",

"state": "NEW",
"message": "",
"id": "68824f4a933ef7b3a5017d39"
}In that case, a second (free) request will be needed to retrieve the desired data.
Retrieve Mobile Number Details
Using the GET /mobile-advanced endpoint, you can retrieve the data made available via the POST request by simply providing the ID.
REQUEST EXAMPLE
GET /mobile-advanced
The endpoint to check the request status is /mobile-advanced and the method used is GET. If you implemented a callback, you’ll be notified when your request has been fulfilled and your data is ready.
This is an example request using the ID obtained from the previous POST call:
GET/mobile-advanced/77e9e92216065fa37f3c9842The response will include the same data described previously, that was available via the POST request.
