CenturyLink Phone Number Lookup

How to Identify CenturyLink Numbers Using Abstract API

You can reliably detect if a U.S. phone number belongs to the CenturyLink network by using Abstract's Phone Number Validation API. The API provides detailed information about any number, including its carrier.

Sign Up and Get Your API Key

First, sign up for a free account with Abstract API. You can get your unique API key from your account dashboard after registering.

Send a Request to the API

Use your API key to send a GET request to the API endpoint. The following Python and JavaScript examples show how to check a number.

Python Example:

import requests

response = requests.get("https://phonevalidation.abstractapi.com/v1/",
    params={"api_key": "YOUR_API_KEY", "phone": "+15558675309"}
)
data = response.json()
print(data["carrier"]) # Will print "CenturyLink" if it’s a CenturyLink number

JavaScript Example:

const axios = require("axios");

axios.get("https://phonevalidation.abstractapi.com/v1/", {
    params: {
        api_key: "YOUR_API_KEY",
        phone: "+15558675309"
    }
}).then(response => {
    console.log(response.data.carrier); // Should output "CenturyLink"
});

Interpret the Response

After sending a request, you will receive a JSON object with details about the phone number. The response will look similar to this:

{
  "phone": "+15558675309",
  "valid": true,
  "country": "United States",
  "location": "California",
  "carrier": "CenturyLink",
  "line_type": "mobile"
}

Here is a breakdown of the key fields in the JSON response:

• phone - Provides the phone number in a standardized international format.
• valid - Returns a boolean value of true if the phone number format is correct.
• country - Gives the country where the number is registered, which is the "United States" in this case.
• location - Indicates the primary geographical location associated with the number.
• line_type - Specifies the type of phone line, such as mobile, landline, or VoIP.
• carrier - Identifies the telecommunications provider for the number. For this example, the provider is "CenturyLink".

To confirm the number belongs to CenturyLink, check that the value for the carrier field is "CenturyLink".

Why Identifying a CenturyLink Phone Number Is Important

Knowing if a phone number belongs to the CenturyLink network helps in verifying user identity and preventing fraudulent activities.

• Fraud Prevention - This allows systems to flag or block numbers from carriers known for high levels of spam or fraudulent sign-ups.
• User Verification - This confirms that a user-provided number is legitimate and associated with a real-world carrier, which adds a layer of security to account creation.
• System Compatibility - This ensures that communication features, like SMS or voice calls, are correctly routed and compatible with the specific network's protocols.
• Data Accuracy - This helps maintain a clean and accurate database by validating that phone numbers are active and belong to a recognized carrier.
