Phone Number Validation

A phone number is arguably the most vital contact point for customers

Why phone number validation is important

There is nothing more frustrating than finding out that someone has submitted an enquiry on your website and the contact number is not valid, a dead number or in the case of mobiles, appears to be switched off.

Use Data Soap's phone validation tools on your website or app

Our API’s allow you to validate phone numbers (both mobiles and landlines) in real-time when data is entered into your web form. This provides you with a valuable validation tool that ensures that only contactable telephone numbers are collected through your data capture sites.

The phone number validation service works with UK and international numbers for mobile phones and UK numbers only for landlines.

  • Mobile Number Validation
  • Landline Number Validation
  • TPS/CTPS & DNC Checking

Other cleansing, validation services we offer

UK & International

Our HLR (Mobile Validation) check allows you to check if a mobile number is live, connected, switched on and what network it is assigned to.

Save your time and money by removing fake, incorrect or dead numbers from your marketing lists.

Landline Validation
UK only

Our landline number validation tool will identify which of your landline numbers are valid and contactable.

Ensuring your landline numbers are valid will help your agents have more conversations and therefore improve conversions.

Email Validation
All email addresses

Use our Email verification tool to remove emails that are incorrectly formatted or undeliverable. Identify ‘free’ emails such as Yahoo! and Gmail.

Email validation will also highlight ‘disposable’ addresses that will become inactive after a short period of time.
