How to Validate Customer Phone Numbers (2 Ways)

Are you looking for ways to validate your customer’s phone numbers?

Phone number verification helps filter invalid leads before they’re added to your database. This way, you’ll save time and cost by only removing fake or inactive numbers.

In this article, we will show you how to validate customer phone numbers using different ways.

Why Validate Customer Phone Numbers?

If you collect customer phone numbers as part of lead generation, then it is important to validate the contact information.

Sometimes, a user might make an error when entering the phone number, providing a fake number, or the number is no longer active. It’s important to verify this information and make sure that your efforts don’t go to waste.

That’s because you can use a valid phone number to provide customer support through a business phone service, deliver shipping details, order information, marketing and sales-related activities, and more.

Plus, you’ll also reduce costs by removing invalid contact information. This is really useful when you’re using marketing tools to send SMS messages, emails, and other messages, as you’ll save credits.

That said, let’s see how to validate customer phone numbers in WordPress. We’ll cover different methods, so you can click the links below to jump ahead to any section.

Method 1: Validate Phone Numbers using WP Simple Pay

If you’re selling digital products online, then you can verify the customer’s phone number using WP Simple Pay. It is the best Stripe payment plugin for WordPress and allows you to accept online payments without setting up a shopping cart.

The plugin offers a phone number validation feature that confirms if a user has entered the phone number correctly. This way, you can reduce the likelihood of typos and errors.

For this tutorial, we will use the WP Simple Pay Pro plan because it includes the phone number validation feature. However, there is also a free version of WP Simple Pay available.

First, you’ll need to install and activate the WP Simple Pay plugin. If you need help, then please see our guide on how to install a WordPress plugin.

Upon activation, you’ll see the WP Simple Pay setup wizard. Simply click the ‘Let’s Get Started’ button to continue.

On the next screen, you’ll need to enter the license key. You can easily find the key in your WP Simple Pay account area.

After entering the license key, you can click the ‘Activate and Continue’ button.

Next, you must connect your Stripe account with WP Simply Pay.

Go ahead and click the ‘Connect with Stripe’ button to move forward.

You’ll now need to login to your Stripe account and follow the onscreen instructions to connect your account.

Now, you’re ready to create a payment form in WP Simple Pay. Simply click the ‘Create a Payment Form’ button.

WP Simple Pay offers multiple form templates to choose from. You can simply add a payment button, donate button, or set up all types of payment forms.

For this tutorial, we will select the ‘Payment Form’ template. You can hover over the template and click the ‘Use Template’ button.

Next, you can edit your payment form.

In the General settings tab, you’ll see options to change the form title, description, form type, payment success page settings, and more.

After that, you can switch to the Form Fields tab to add or remove different fields in your payment form.

By default, WP Simple Pay won’t add the phone number field.

To add the field, simply click the Form Fields dropdown menu and select the ‘Phone’ field. Once you’ve selected it, click the ‘Add Field’ button.

Next, you can expand the Phone field and further customize it, like editing its label and making it a required field.

For phone number verification, make sure that you enable the ‘Offer Smart Phone Number Validation’ option and select the default country.

Aside from that, you can edit other form fields and rearrange their order by simply dragging them up or down.

Once you’re done editing, go ahead and click the ‘Publish’ button.

Next, you can add the payment form on any page or post on your WordPress site.

Simply edit or add a new post or page. Once you’re in the content editor, click the ‘+’ icon and add the ‘WP Simple Pay’ block.

Now, click the dropdown menu in the block to select your payment form. Once that’s done, simply publish or update your page.

You can now visit your website to see the payment form with the phone number validation option.

When a user enters an invalid phone number, they will not be able to move ahead in the form.
