Data is a very pure and natural resource that benefits us in many ways today. By obtaining and analyzing the data that our businesses need, we gain advantages in many areas, such as growth, development, and getting ahead of our competitors.
The fact that data has become important to us, on the other hand, brought the responsibility of protecting and hiding it.
Today, many businesses use a phone number lookup free API that serves free phone number lookup in order to prevent attacks due to data vulnerabilities.
We can easily prevent many data breaches that we may encounter in the digital age with a phone number lookup free API.
Thanks to this API, we also have the advantage of doing this for free. The most common use of this API today is to detect typical scams. So how do we do this with a free phone number lookup API?
What are the Common Use Cases For Detecting Typical Scams With A Free Phone Number Lookup API?
Free phone number lookup APIs are an important tool in helping us learn about a phone number and detect potential threats such as fraud. Common use cases of this API to detect scams are as follows:
- Fraud Signs: A free phone number lookup API provides us with unique data about the phone number. Using this data, we can investigate signs of fraud. For example, the target phone numbers may have been associated with another fraudulent event or used in similar fraud cases. Also, the number may be an invalid number or a fake one.
- Detection of Fake Campaigns: This API usually provides us with the country and location information of the target phone number. Scammers can often set up fake campaigns by calling from other countries. Therefore, using this API we have a better chance of detecting suspicious activities by checking if the number is suitable for the specified country and location.
- Line Type Detection: With a free phone number lookup API, we also obtain line type information of the target phone number. Line type indicates whether the number belongs to different line types, such as mobile, fixed line, or VoIP. Scammers can employ different scam tactics using certain types of lines. For example, mobile lines are often used in SMS scams. With this API, we can get an idea of potential fraud types by verifying the line type.
How Should Be A Good Phone Number Lookup API For Detecting Typical Scams?
A phone number lookup API should have some key features to detect typical scams.
When choosing a phone number search API, you should consider these features. In this section, we’ll cover some of these features.
- Verifying Number Validity: A phone number lookup API should provide a “valid” or similar field that allows users to check if the number is a real phone number. It is important to detect valid numbers to prevent fraudulent or false numbers. This also allows you to have a user database with verified records.
- Country and Region Information: This API should provide information such as the country code and country name to which the number is linked. This will directly help users to locate the number in an accurate geographic location and detect fake international numbers.
- Carrier Information: It is very important for a phone number lookup API to provide a “carrier” field that shows the telecom operator the number is affiliated with. Today, official phone number lookup APIs such as the numverify API provide this field. Scammers can try to hide their tracks by using sim cards of different operators. Therefore, it is quite important to check whether the number belongs to a real operator.
- Line Type Information: One of the anti-fraud steps is that the API offers a “line_type” field that indicates whether the number belongs to different line types such as a mobile line, landline, or VoIP. Scammers can employ different scam tactics using certain types of lines. This information will help you quickly get an idea of potential types of scams.
- Number of Countries Supported: It is very important that this API has a large number of countries supported for phone number lookup. The more countries this API supports in the world, the more you can gain a global advantage to prevent fraudulent activities.
- Fast and Reliable Response: The API must respond quickly and reliably and allow users to access data easily. It should be an easy-to-use API. This makes the fraud detection process more effective and efficient.
How to Use A Free Phone Number Lookup API With Golang To Spot Scams?
In this section, we will examine step by step how we can use a free phone number lookup API for spot scams.
For this, we will use the numverify API, which is a very popular phone number lookup API that offers us free service and supports 232 countries.
To use this API, first of all, let’s register for the free subscription plan it provides. This plan gives us a monthly API call limit of 1,000. After registration, we will get an API key.
Then, let’s open a file named ‘phone-number-lookup-with-api.go’ in the file path where we will develop the application and put the following codes in it:
package main
import (
“fmt”
“net/http”
“io/ioutil”
)
func main() {
url := “http://apilayer.net/api/validate?access_key=YOUR-ACCESS-KEY&number=14158586273&format=1”
method := “GET”
client := &http.Client {
}
req, err := http.NewRequest(method, url, nil)
if err != nil {
fmt.Println(err)
return
}
res, err := client.Do(req)
if err != nil {
fmt.Println(err)
return
}
defer res.Body.Close()
body, err := ioutil.ReadAll(res.Body)
if err != nil {
fmt.Println(err)
return
}
fmt.Println(string(body))
}
Let’s put our own API key in the ‘YOUR-ACCESS-KEY’ field in this code and run our application easily with the following command.
go run phone-number-lookup-with-api.go
The phone number lookup response that we can use in spot scams after running the application is as follows:
{
“valid”:true,
“number”:”14158586273″,
“local_format”:”4158586273″,
“international_format”:”+14158586273″,
