E commerce Best Practices for Phone Number Validation in 2024

A phone number validator is a software tool that allows you to verify phone numbers. Users just need to provide the phone number they want to validate, and the tool verifies the authenticity and accuracy of the number. Some tools also support bulk phone number validation to save time.

An efficient phone validation tool, such as a phone validation API, usually provides the following information:

  • Existence of the Phone Number: Verifies whether the given phone number exists and is currently used by someone.
  • Format Validation: Checks if the given phone number format is correct according to the format of a specific region of the country.
  • Phone Line Type Identification: Identifies the line type of phone number, such as landline, mobile, or Voice over Internet Protocol (VoIP) numbers. Efficient phone validators can validate different types of phone numbers, such as personal and business numbers, landline phone numbers, mobile numbers, etc.
  • Carrier Details: Some tools also provide carrier details associated with the phone number.
  • Location Information: An efficient phone validator tool also provides location information associated with the phone number, including country and city.

Why Phone Number Validation is Crucial in E-commerce?

E-commerce businesses worldwide collect the phone numbers of their customers through form submissions for various purposes, such as order processing, communication, customer service, and timely delivery of orders. Ensuring that the phone numbers you collect are valid and up-to-date is crucial for a successful e-commerce operation.

Here are some key reasons why validating phone numbers is essential for e-commerce businesses:

Effective Communication with Customers

Effective communication between an e-commerce business and customers is the key to enhancing the customer experience. It helps businesses contact customers to resolve issues, provide order updates, and send delivery notifications. However, this communication is only possible if you have the correct phone numbers of your customers.

Customers sometimes provide incorrect numbers mistakenly. By validating phone numbers, you can identify invalid phone numbers and request customers to provide the correct version. On the other hand, if you don’t validate phone numbers, you might be sending order updates and delivery notifications to the wrong numbers. This leads to customer frustration, resulting in negative reviews and lost revenue. Moreover, contacting customers on invalid numbers results in wasted time and resources.

Order Verification and Confirmation

Accurate phone numbers help e-commerce businesses send order verification and confirmation messages to customers. This, in turn, helps them ensure that customers receive the right products, leading to customer satisfaction. However, without order verification and confirmation, businesses may have to bear the costs of returns.

Timely Delivery of Products

Phone number verification and validation are also helpful in delivering products on time. When businesses have accurate customer phone numbers, they can effectively coordinate delivery times with customers. This ensures that customers receive orders when expected. Moreover, valid phone numbers also help businesses with address verification and receipt availability.

On the contrary, invalid or incorrect phone numbers can result in failed deliveries. For instance, you can’t coordinate delivery details or confirm the recipient’s availability with an inaccurate phone number. This leads to customer dissatisfaction and also results in additional costs for redelivery.

Customer Service

Valid and accurate phone numbers of customers enable e-commerce businesses to improve their customer service, resulting in satisfied customers. For instance, businesses can directly contact customers to resolve their issues, address concerns, and respond to their queries.

SMS Marketing

SMS marketing is an effective way to capture leads and promote products. In SMS marketing, businesses send promotional messages and offers to phone numbers in their customer database. Using a phone number validation tool, e-commerce businesses can maintain a clean marketing database with authentic and genuine phone numbers. This helps them ensure their messages reach the intended audience.

On the other hand, sending text messages to invalid phone numbers means your target audience never received those messages. This results in ineffective marketing and wasted resources.

Fraud Prevention

A phone validator can also serve as a powerful tool for fraud prevention. For instance, it can help businesses confirm customers’ identity during registration or checkout. E-commerce businesses can also implement multi-factor authentication (MFA) or 2-factor authentication (2FA) and use customers’ phone numbers to verify their identity.
