If you've received a D&B professional contact data notification, you're probably wondering what it is, why you got it, and whether it's even real. Short answer: it's a compliance notice from Dun & Bradstreet informing you that they hold professional contact data about you in their database. It is not a marketing email, a sales pitch, or (usually) a scam.

But there's more to unpack. This guide walks you through exactly what D&B's professional contact data program is, what information they collect, how they use it, and — most importantly — what you can do about it.

What Is Dun & Bradstreet (D&B)?

Dun & Bradstreet is one of the oldest commercial data companies in the world — nearly 200 years old. They maintain a massive database of business information, including company records, financial data, and professional contact data about decision-makers and employees at organizations worldwide.

Their most well-known product is the D-U-N-S Number, a unique nine-digit identifier assigned to businesses globally. But D&B also operates a large-scale B2B contact data business through products like D&B Hoovers, their Contact Directory, and various API solutions that help sales and marketing teams find and reach business professionals.

In practice, D&B is one of the major B2B data providers that companies use to build prospecting lists, run account-based marketing campaigns, and verify business information.

What Is D&B Professional Contact Data?

D&B's Professional Contact Data is a dataset that connects individual professionals to the organizations they represent. It's organized by business entities and corporate families, not by individuals — meaning your data is stored in the context of where you work.

According to D&B's own Transparency Statement (Version 3.2, effective September 2025), their Professional Contact Data typically includes:

• Name — first, middle, last, prefix, and suffix

• Job title and job level

• Current and former employers

• Business postal address (plus latitude/longitude based on zip code)

• Professional email address

• Mobile, office, and fax numbers

• Social media links and URLs

• Professional license numbers (where publicly available)

This data covers both current and former professional roles. If you've changed jobs, D&B may still have records from your previous positions.

Why Did You Receive This Notification?

The D&B professional contact data notification is a transparency and compliance notice. It's sent to inform you that Dun & Bradstreet processes professional contact data about you.

This isn't a marketing communication. D&B sends these notifications for two reasons:

1. Regulatory compliance — Privacy laws like GDPR (Europe), CCPA (California), and similar regulations worldwide require companies to inform individuals when their personal data is being processed. D&B sends these notices to meet those obligations.

2. Transparency commitment — D&B positions itself as a "responsible data steward" and proactively notifies people about data processing even in jurisdictions where it may not be strictly required.

The notification typically comes from noreply@compliance.dnb.com and states that "The Dun & Bradstreet Corporation processes Professional Contact Data about you." It's purely informational — it's telling you they have your data, how they use it, and what you can do about it.

Is the Notification Legitimate or a Phishing Attempt?

This is the question most people have. The short answer: legitimate D&B notifications do exist, but phishing emails impersonating D&B also circulate. Here's how to tell the difference.

Signs It's Legitimate

• The sender address is noreply@compliance.dnb.com (check the actual email header, not just the display name)

• The email does not ask you to log in, download an attachment, or provide sensitive personal information like passwords or financial details

• It references D&B's Professional Contact Data Transparency Statement and links to dnb.com domains

• The tone is formal, compliance-oriented, and non-urgent

Red Flags That Suggest Phishing

• Suspicious sender address — long, random strings in the email address (e.g., "9z3zuffoh0imk76@compliance.dnb.com") are a known red flag

• Urgent language — "Act now or your account will be suspended" is not how D&B communicates

• Attachments — legitimate D&B notifications don't include attachments. Malware samples disguised as "D&B Professional Contact Data Notification" files have been detected in the wild

• Requests for passwords or payment — D&B will never ask for these in a transparency notice

• Links to non-D&B domains — hover over any links before clicking. They should point to dnb.com

When in doubt: don't click any links in the email. Instead, go directly to dnb.com and navigate to their Trust Centre or data transparency page manually. D&B has also published alerts warning about phishing emails that impersonate them.

What Does D&B Do With Your Professional Contact Data?

D&B licenses professional contact data to its customers — other businesses — for a range of purposes:

• B2B marketing and digital advertising — Companies use D&B data to target ads and campaigns at specific job titles, industries, or company sizes

• Sales and business development — Sales teams use D&B Hoovers and similar tools to find contact details for prospects

• Finance and risk management — Credit teams use it to verify identities and assess business relationships

• Procurement and supplier management — Companies vet potential vendors and suppliers

• Regulatory compliance — Organizations verify business contacts for KYC (Know Your Customer) and due diligence requirements

D&B also uses your data within their AI-powered tools. Their Chat D&B AI solution can surface your professional contact data in response to client queries. SmartMail AI in D&B Hoovers helps customers generate email messages addressed to you. And SmartSearch uses AI to return your contact information in search results.

In short, if you're a professional at a business, there's a good chance your name, title, and contact details are being used to help other companies find and reach you.

Where Does D&B Get Your Data?

D&B sources professional contact data from over 2,000 commercial and public data sources, including:

• Public websites — company websites, LinkedIn profiles, industry directories

• Partner data providers — third-party data vendors that share or sell professional information

• Direct collection — data submitted through D&B websites, forms, and online tools

• Modeled data — D&B predicts some contact details (particularly email addresses) based on formatting patterns at a company. For example, if a company uses firstname.lastname@company.com, D&B may generate predicted emails for other employees at that company

D&B assigns an "Accuracy" score to predicted email addresses based on a multi-point validation process. Only emails with higher accuracy scores make it into their solutions.

The company says it refreshes the majority of its professional contact data at least quarterly, with some data refreshed monthly or weekly. Email addresses are validated at the mail server level quarterly, and phone numbers are tested for connectivity at least twice a year.

Understanding where contact data sourcing happens and how it flows into B2B tools is important for any professional who wants to manage their digital footprint.

Your Rights: How to Manage or Opt Out

You have several options for managing what D&B does with your professional contact data. Your exact rights depend on where you're located, but here's what's generally available.

Update Your Data

If D&B has inaccurate information about you — wrong job title, outdated employer, incorrect email — you can request corrections. Visit D&B's Data Update page at dnb.com/utility-pages/data-update.html to submit changes.

Manage Communication Preferences

D&B offers a Communication Preferences management tool where you can update how they contact you. Visit dnb.com and look for their communication preferences page.

Opt Out of Data Sales

To opt out of D&B sharing or selling your professional contact data:

1. Go to dnb.com

2. Find the "Do Not Sell My Personal Information" link (typically in the footer)

3. Enter your email address

4. Complete the opt-out form with your name, company, job title, phone number, email, and country

5. Submit the request

D&B typically responds within 15 days. You can also call them directly at 800-526-0918 (US) for assistance.

Exercise GDPR/CCPA Rights

If you're in the EU, you can contact D&B's data protection officer at eudpo@dnb.com. Their designated EU representative is D&B Business Information Solutions Unlimited Company, based in Dublin, Ireland. You also have the right to lodge a complaint with your local data protection authority.

Under CCPA (California) and similar US state privacy laws, you have the right to know what data is collected, request deletion, and opt out of data sales.

Maintaining accurate records across data systems is a broader challenge for B2B teams — if you're on the other side of this equation, a solid data quality governance framework helps keep contact data clean and compliant.

How D&B Professional Contact Data Fits Into the B2B Data Landscape

D&B is one of many companies that collect and license professional contact data. The broader B2B data ecosystem includes:

• Business data aggregators — D&B, ZoomInfo, Apollo, Clearbit, and others maintain large databases of professional contacts

• Data enrichment platforms — Services that take basic contact information and append missing fields like email, phone, job title, or company details

• Intent data providers — Companies that track buying signals to help sales teams prioritize outreach

• Public data scrapers — Tools that collect publicly available professional data from LinkedIn, company websites, and directories

What makes D&B distinctive is their scale (200 years of business data, 2,000+ data sources) and their focus on company-level organization. Your contact data isn't just stored as a standalone record — it's linked to your employer's D-U-N-S Number and the broader corporate family tree. This makes D&B particularly strong for account-based approaches where understanding organizational hierarchy matters.

If you're interested in how data enrichment works across different providers and why single-source data has limitations, it's worth understanding the waterfall enrichment model — where multiple data sources are queried in sequence to maximize accuracy and coverage.

What to Do After Receiving the Notification

Here's a practical checklist for anyone who just received a D&B professional contact data notification:

1. Verify it's legitimate — Check the sender address and look for the red flags listed above. Don't click links if anything looks suspicious.

2. Review the Transparency Statement — Go directly to dnb.com and read their Professional Contact Data Transparency Statement to understand what data they hold and how it's used.

3. Decide your preference — Do you want to leave your data as-is, update inaccurate information, or opt out entirely?

4. Take action — Use the appropriate channel: Data Update page for corrections, "Do Not Sell" form for opt-out, or eudpo@dnb.com for EU-specific rights.

5. Monitor for phishing — Be aware that scammers imitate D&B notifications. If you receive follow-up emails requesting passwords, attachments, or payments, those are fraudulent.

The key point: receiving this notification doesn't mean anything bad happened. It's a routine transparency notice. But it is a reminder that your professional data is actively being traded in the B2B data marketplace.

How Accurate Is D&B Contact Data?

D&B claims to maintain data quality through standardization, validation, cleansing, and matching processes. They verify email addresses at the mail server level quarterly and test phone numbers for connectivity at least twice a year.

That said, no single data provider has perfect accuracy. Industry data shows that B2B contact databases typically decay at a rate of 25–30% per year as people change jobs, companies merge, and contact details go stale. D&B's quarterly refresh cycle helps, but gaps are inevitable — especially for fast-moving industries or smaller companies.

This is why many B2B teams don't rely on a single data source. Instead, they use multiple providers or enrichment platforms that aggregate data across sources to improve contact data validation and coverage rates.

If you've found that D&B has inaccurate data about you, it's worth correcting it — not just for your own sake, but because inaccurate contact data leads to wasted outreach from sales teams who don't realize the information is outdated.

D&B Data and AI: What You Should Know

One relatively new development in D&B's notification is the mention of AI-powered tools that use your professional contact data. This includes:

• Chat D&B — An AI chatbot that D&B customers can query to find professional contacts. Your data may surface in AI-generated responses.

• SmartMail AI — A feature in D&B Hoovers that uses AI to help customers draft outreach emails targeted at you.

• SmartSearch — An AI-powered search function that may return your professional contact data in results.

This is part of a broader trend across the B2B data industry. AI is being layered on top of contact databases to make it faster and easier for sales and marketing teams to find and engage professionals. Your professional data isn't just sitting in a database — it's being actively used to generate personalized outreach at scale.

For professionals who want to understand how their data moves through B2B systems, learning about firmographic data and how companies like D&B link individual contacts to organizational profiles gives useful context.

Key Takeaways

• A D&B professional contact data notification is a legitimate compliance notice — not spam, not a sales pitch

• D&B collects your name, job title, employer, email, phone, and social links from 2,000+ sources

• They license this data to other businesses for marketing, sales, risk management, and compliance purposes

• You can update, correct, or opt out of your data through D&B's website or by contacting them directly

• Watch for phishing — real notifications come from noreply@compliance.dnb.com and never ask for passwords or attachments

The notification is ultimately a reminder that in B2B, professional contact data is a commodity. Companies collect it, verify it, license it, and use it to connect with professionals who might be interested in their products or services. Whether you view that as a useful part of the business ecosystem or a privacy concern is up to you — but at least now you know exactly what's happening with your data and how to take control of it.
