Let us answer your questions.

We're on a different journey and we know you might have some questions about it.

Identity & Identity Resolution
What is Identity Resolution?

Identity Resolution is the practice of connecting and consolidating all the identifiers of an individual that may exist on multiple platforms and devices and mapping them to one person. This allows brands to better leverage the data they already have on their customers, enabling the ability to gain unparalleled recognition and insights.

How does Identity Resolution work?

Identity Resolution typically relies on assumptions and modeling to confirm identity. Our Identity Resolution is different, using our Person-Centered Graph™ to process data from public and private sources. We use machine learning to determine confidences on different components of a person's identity, for example letting you know how sure an individual’s email is truly theirs. This allows us to resolve identity to a person in ways that others simply cannot.

What is an identity graph?

An identity graph connects disparate consumer identifiers into an accurate and complete customer view.

In order to better understand a single individual, we need to understand the fragmented pieces of who they are. An identity graph is a collection of nodes and edges, where the nodes are contact fragments and the edges are the connections between them. A grouping of nodes and connected edges represents a whole person, formed in the graph.

Effective Identity Resolution and customer profile development depends on the precision, depth, and scale of the identity graph.

How do I connect my unorganized customer data?

Identity Resolution solves the issue of fragmented, siloed, and incomplete customer information by taking all the disparate identifiers and touchpoints of an individual that may exist on multiple platforms, devices, and channels and attaching them to one person.

How is the identity graph different from traditional Identity Resolution capabilities?

Where other organizations use a table of identifiers to look up identifiers enact Identity Resolution, our identity graph uses machine learning to predict patterns, ingest new information, and determine the confidence scores of linkages. The identity graph has the ability to learn and adapt in real-time, which provides you with the most up-to-date information.

By facilitating more connections across data streams, the identity graph amplifies a brand’s own data. Access to our identity graph supports a range of use cases, including enriched customer insights, expanded customer engagement, connected customer experiences, and honoring customer preferences.

How should I evaluate an identity graph?

Determine how you plan to use an identity graph. Many graphs are only device-focused, ours is person-centered. Most graph providers also charge for any query. We only charge for successful identified individuals—this increases the effectiveness of our customers spend by always delivering value. Additionally, it's important to evaluate three critical components for analyzing data: Scale, Precision, and Depth. Scale measures the top line number of devices and people represented by the graph; it’s a leading indicator of activation reach, match rates, and customer profiles. Precision measures the proportion of identifiers correctly linked to the same person; it’s the starting point for evaluating linkage accuracy. Depth measures the number of identifiers per cluster, such as number of devices per person; it drives addressability across touchpoints and persistence over time.

How does FullContact approach accuracy?

At FullContact, we assign a probability on each edge of our graph and adjust that probability millions of times a day as we see positive evidence or we downgraded by negative evidence. This positive and negative evidence is combined in what we call a Belief Vector. Every connection has two “scores” that indicate the positive reinforcement and negative undermining of the connection itself. We can then calibrate the belief we have in a collection of contact fragments into the representation of a real person. You can tune the confidence levels of the belief vectors to get the results you’re looking for.

Security & Privacy
What steps does FullContact take to secure personal data?

FullContact places a premium on staying at the forefront of privacy and security practices. FullContact is SOC2 Type 2, PCI, Cloud Security Alliance, and U.S.-EU/Swiss Privacy Shield compliant, and employs a GDPR (CIPP/E) certified executive as a central part of its corporate leadership. Learn more about our approach to privacy here.

Is FullContact GDPR compliant?
Is FullContact CCPA compliant?

Yes! While CCPA is an ever-evolving law, we're following it closely and going beyond what's required. Learn more about our approach to privacy here.

If my organization provides Mobile Ad IDs or Cookies, can we receive names & address information?

No. FullContact is not in the business of selling datasets or providing PII your organization does not already have, nor do we sell name/address databases derived from MAIDs or cookies. We help you ​​easily connect your first-party customer & prospect data across your platforms. You can read our person-first stance on privacy here and our privacy policy here.

Do you sell lists or audiences for marketing purposes?


What kinds of companies do you not do business with?

We don’t sell Identity Resolution products or solutions to political organizations, foreign governments, companies looking for Identity Resolution outside of the United States, bad actors, or companies that don’t align with our brand ethics.

API & Identifiers
What inputs can you take?

We can take numerous inputs, including name/address, phone numbers, personal and/or professional emails (hashed and/or plain text), social username/ID, Mobile Ad IDs, PersonID (if you’re using Resolve), and Customer RecordID (if you’re using Resolve).

How do matches affect billing?

It’s simple. Unlike others, we only charge you when FullContact delivers value. If you request data from us, and we have something to share (a 200 Response for our technical readers) that is a match. For plans billed by match, if we don’t return data, you won’t be charged.

What is a Mobile Advertising ID?

A Mobile Advertising ID (MAID), sometimes called a mobile device ID, is a unique, anonymous hexadecimal number that iOS or Android assigns to each device to track user activity for advertising. Mobile Ad IDS from iOS are called IDFAs and those that Android assigns are AAIDs.

We make combining online and offline customer data easy. It’s important to recognize the data you already have, and look how it can be matched across channels. Our Resolve capability matches your inputs to individuals, then maps a persistent identifier to those individuals. The persistent identifier, or PersonID, is specific to you and your customers or prospects. Once you map to a PersonID, you have the online and offline data in a single, easy-to-manage profile.
