GDPR and Number Verification: why the two go hand in hand

Beyond consent forms, here is the often-overlooked side of GDPR compliance

When you think of GDPR, you probably picture cookie banners and consent checkboxes. 

However, real compliance runs deeper, especially when it comes to how you manage and store customer contact data.

Invalid or outdated phone numbers don’t just waste time and budget; they also pose a compliance risk. GDPR requires you to maintain accurate, relevant, and secure personal data, and that’s where number verification (and HLR Lookup) comes in.

Maintain data accuracy and keep contact records up to date

Under Article 5 of the GDPR, data must be “accurate and, where necessary, kept up to date.

Therefore, if your CRM contains inactive or invalid numbers, you could be processing incorrect personal data.

HLR Lookup instantly identifies invalid or inactive phone numbers, so you only store live, reachable contacts, keeping your database compliant and up to date.

Minimise your data by only keeping what you need

The GDPR principle of data minimisation means you should only collect and retain the data you actually use.

By verifying numbers before storing or messaging them, you eliminate unnecessary records and reduce your exposure in the event of a data breach.

This results in a smaller, more compliant dataset that’s easier to manage and defend.

Protect your data and brand through security and fraud prevention methods

Fraudulent or disposable numbers can expose your business to security and reputational risks.

Although with network-level verification, HLR Lookup flags disposable or suspicious numbers before they enter your into your system, helping to protect and detect patterns of misuse, and keep your data secure.

All this is achieved without processing any personal information; we provide technical insights about network status, so consumer privacy will always remain intact.

Real consent can only start with real numbers

You can’t obtain valid consent from numbers that don’t exist.

By verifying mobile numbers at the point of collection, you make sure every opt-in is legitimate, every message is deliverable, and every consent record holds up under GDPR scrutiny.
