Enhancing Customer Data Quality with numverify’s Phone Number Validation Tool

Customer data is like a gold mine for businesses. For example, companies collect customers’ contact information to personalize customer experiences, improve customer support services, send promotional offers, and enhance their marketing campaigns. This, in turn, helps companies build stronger relationships with customers and improve retention rates. However, customers can sometimes provide wrong numbers mistakenly. Moreover, scammers often use fake numbers for fraudulent activities, such as creating fraudulent accounts. The auto-fill feature in browsers also fills in outdated or incorrect information sometimes, resulting in incorrect phone numbers. Thus, ensuring customer data quality is crucial. This is where a reliable phone number validation tool is helpful.

Numverify is a powerful and highly accurate phone validator and lookup API service. It helps ensure that phone numbers collected from customers are accurate, valid, and up-to-date. Thus, numverify plays a crucial role in enhancing customer data quality.

Benefits and Applications of a Phone Number Validation Tool

Improved Data Accuracy

Phone validation tools are crucial for ensuring the accuracy of customer contact information. These tools can check the validity of a number at the point of entry. This prevents typos and formatting errors, ensuring there aren’t any invalid phone numbers in your database.

These tools can also format phone numbers into a standardized, consistent format. This ensures uniformity.

Moreover, validating phone numbers reduces the bounce rate of messages or failed calls. This ensures that marketing messages, alerts, and notifications are successfully delivered to the right customers.

Enhanced Customer Communication and Experience

Using a phone number validator allows businesses to ensure that phone numbers are valid and active. This increases the chances of successful direct communication with customers. This is especially crucial for time-sensitive communications, such as delivery notifications, order confirmations, and customer support.

Moreover, tools like numverify also show the type of phone number, such as mobile, landline, or VoIP. This allows businesses to communicate more effectively with customers. For example, many VoIP and landline numbers do not accept SMS messages. Thus, businesses can prevent undelivered messages by detecting phone number types.

Geolocation data from phone number verification can also help businesses provide personalized experiences to users. For example, they can send region-specific offers and updates.

Operational Efficiency

Integrating a phone number validation tool into your system automates the verification process. This reduces manual work and saves time. Automation also ensures higher customer data accuracy, leading to more efficient and reliable operations.

Moreover, by preventing invalid numbers from entering the database, businesses save on costs associated with failed communication and wasted marketing efforts.

Fraud Prevention

Verifying phone numbers helps identify potentially fraudulent or inactive numbers. This reduces the risk of fraudsters using fake or disposable phone numbers.

Valid phone numbers can also be used for multi-factor authentication (MFA). This adds an extra layer of security for verifying user identity.

Moreover, businesses can use carrier detection to flag suspicious carriers associated with higher fraud instances.

A phone number validator tool can also help with user identity confirmation. For example, businesses can check if the location data provided by the phone validation tool matches the location information given by the customer. If they don’t match, they can flag the number and investigate it further.

Basic API Request

Number validation

Here is an example API request for validating a phone number:

http://apilayer.net/api/validate
    ? access_key = YOUR_ACCESS_KEY
    & number = 14158586273

National (local) numbers

Numverify also allows you to specify a phone number in its national (local) format. You need to add additional country information/2-digit country code:

http://apilayer.net/api/validate
    ? access_key = YOUR_ACCESS_KEY
    & number = 4158586273
    & country_code = US

JavaScript Fetch

const url = 'https://apilayer.net/api/validate?access_key={PASTE_YOUR_API_KEY_HERE}&number=14158586273';
   const options = {
      method: 'GET'
   };

   try {
      const response = await fetch(url, options);
      const result = await response.text();
      console.log(result);
   } catch (error) {
      console.error(error);
   }

JavaScript Axios

import axios from 'axios';

   const options = {
   method: 'GET',

   params: {
      number: "14158586273",
   }
   };

   try {
      const response = await axios.request(options);
      console.log(response.data);
   } catch (error) {
      console.error(error);
   }

Python Requests

import requests

   url = "https://apilayer.net/api/validate?access_key={PASTE_YOUR_API_KEY_HERE}"

   querystring = {"number":"14158586273"}

   response = requests.get(url, params=querystring)

   print(response.json())

Parsing and Utilizing Data

url = f"http://apilayer.net/api/validate?access_key={api_key}&number={phone_number}"
response = requests.get(url)
data = response.json()

carrier = data['carrier']
location = data['location']
line_type = data['line_type']

print(f"Carrier: {carrier}")
print(f"Location: {location}")
print(f"Line Type: {line_type}")

Parsing JSON response and extracting data (JavaScript/Node.js)

const axios = require('axios');
const apiKey = 'YOUR_API_KEY';
const phoneNumber = '14158586273';

axios.get(`http://apilayer.net/api/validate?access_key=${apiKey}&number=${phoneNumber}`)
  .then(response => {
    const data = response.data;
    const carrier = data.carrier;
    const location = data.location;
    const lineType = data.line_type;

    console.log(`Carrier: ${carrier}`);
    console.log(`Location: ${location}`);
    console.log(`Line Type: ${lineType}`);
  })
  .catch(error => {
    console.error(error);
  });
