What IT / Operations leaders need for SMS Verification in UK's Real Estate sector (2026)

Introduction

In the UK's competitive Real Estate market, verifying user identities is crucial for preventing fraud and ensuring compliance with regulations. One of the most significant challenges IT and Operations teams face is reducing the number of failed One-Time Passwords (OTPs) sent via SMS. Failed OTPs can frustrate users, lead to increased support requests, and result in potential revenue losses. Real Estate businesses should optimize their SMS verification processes to minimize failed OTPs and improve overall customer experience.

Why SMS fits transactional Verification

SMS remains a widely used and effective channel for transactional verification in the UK. Its ubiquity, coupled with the fact that SMS messages are typically read quickly, makes it an ideal choice for time-sensitive verification processes. With the continued adoption of mobile devices and the importance of security, SMS verification is critical for Real Estate businesses looking to protect their users and comply with regulations such as PECR and GDPR.

Real-World Examples

Several companies have successfully implemented SMS verification to improve their verification processes. For example:

Foxtons

A leading UK estate agency implemented a robust verification process using SMS, resulting in improved user trust and security.

Purplebricks

Another prominent UK estate agency streamlined their user verification process with SMS, leading to a better user experience and reduced support requests.

Zoopla

A leading UK property portal enhanced the security and efficiency of their user verification process using SMS, resulting in improved verification rates and reduced fraudulent activities.

How the program works end-to-end

The verification program is designed to be seamless and efficient. Here’s how it works:

  • User Initiation: The user initiates the verification process.
  • OTP Generation: An OTP is generated and sent to the user via SMS.
  • User Verification: The user enters the OTP to complete the verification process.
  • Follow-up: If the OTP fails, the system can be set up to send follow-up messages or alerts to the user and support teams.

Compliance notes for UK

In the UK, compliance with regulations such as PECR and GDPR is essential when implementing SMS verification. Businesses must ensure that users have given consent to receive SMS messages and adhere to Sender ID UK guidelines.

Cost / ROI considerations

The cost of implementing an SMS verification system can vary based on the volume of messages and the provider's pricing. To achieve a positive ROI, it's crucial to minimize failed OTPs, which can be costly in terms of support requests and potential revenue loss. By optimizing the verification process, businesses can see significant cost savings and improvements in user experience.
