How did ZoomInfo get my information?

A UK guide for professionals. Last reviewed October 2026.

If a salesperson has called your work number or emailed you out of the blue, there is a good chance they found you on ZoomInfo. Here is where ZoomInfo says its data comes from, why your details may be out of date, and how to get them removed.

Where ZoomInfo says its data comes from

ZoomInfo describes four main sources on its own website.

• Public websites. Automated software reads public information on millions of websites, such as company pages, press releases, news articles and job adverts. It also collects business contact details that people publish themselves, for example on a firm's staff page.
• Data partners. Other companies supply data to ZoomInfo, such as job postings and information used to standardise addresses.
• A contributor community. ZoomInfo says more than 200,000 professionals use a free version of its tools and share business contact information in exchange for access. This means your details can reach ZoomInfo even if you have never used it yourself.
• Its own research team, which checks, adds to and corrects records.

Why your details may be out of date

Profiles are built from many sources over time, so they can show an old job title or an email address from an employer you have left. That is why some callers ask for you by a previous role. In our own pilot sweep, another sales database still held a work email address from a job the person had already left.

Why sales teams can see your number

ZoomInfo sells access to its database. Its customers can search for people by job title, company or location and see work email addresses and direct phone numbers. One profile can be seen by many different sales teams.

How to get your details removed

1. Go to the Privacy Center on ZoomInfo's website, which is linked from its privacy policy.
2. Enter the work email address ZoomInfo holds for you, then the code it sends to that address.
3. Choose the option to delete your information and submit the request.
4. If you no longer have that email address, write to ZoomInfo's privacy team instead. Object to the use of your data for direct marketing and ask for it to be erased.

Our step-by-step ZoomInfo opt-out guide covers this in more detail.

Your rights under UK law

Your name, work email address and direct phone number are personal data. You have an absolute right to object to their use for direct marketing, and in many cases a right to have them erased. Companies based outside the UK can still be subject to UK data protection law when they process the details of people in the UK. A company must normally respond within one calendar month.

ZoomInfo is only one of many

The same details are often held by several sales databases at once. ColdStop Pro sends formal requests to ZoomInfo, Apollo, Lusha, Cognism, RocketReach and more than 20 other sales databases on your behalf, deals with the replies, follows up with any that do not respond, and reports every outcome. Plans start at £29.
