Marketers are tasked with managing an inordinate amount of data. The often-anonymous consumer journey is complex and rapidly evolving, encompassing numerous channels and devices. Marketers are left needing to decipher the pieces in an attempt to create cohesive customer profiles that enable personal, purposeful interactions.
Deterministic identity resolution helps marketers overcome the complexities of fragmented data points with identity services designed to deliver actionable results. Here’s how this process powers personalized experiences with unified customer views.
What is Deterministic Identity Resolution?
Deterministic identity resolution resolves disparate data points into complete customer profiles. Identity resolution is a fundamental process that assembles disparate identifiers to construct a comprehensive understanding of your customers.
How Deterministic ID Resolution Works
Below are a few of the main components of the identity resolution process when it’s powered by deterministic data:
Data Collection
Customer data is collected from various sources, including online and offline channels. This data forms the foundation of deterministic ID resolution, where known identifiers (like email addresses or phone numbers) are used to match customer interactions across touchpoints with high confidence.
Online Data Collection Examples:
- Website interactions, such as logins and account activity
- Contact form submissions
- Product views and cart activity (tracked when logged in or via known identifiers like email)
- Email engagement, such as email opens, clicks, and conversions tied to a specific email address
- Mobile app behavior tied to a logged-in user
- Device IDs and push notification responses
- E-commerce transactions such as purchases linked to a customer profile via checkout credentials (e.g., email or loyalty ID)
- Customer Support Chat information, such as live chat interactions when authenticated or tied to CRM records
- Social Media engagement via integrations (when users log in via social profiles or interact through authenticated brand channels)
Offline Data Collection Examples:
- In-store purchases, such as loyalty program swipes or phone/email collection at checkout, and POS systems recording known customer purchases
- Call Center interactions, like phone support logs tied to customer profiles through caller ID or account verification
- Direct Mail campaigns, such as responses tracked via unique codes or URLs tied to customer records
- Events and trade shows, like badge scans or sign-ups using email addresses or business cards
- Surveys or paper forms, including physical forms collected at stores or events with identifiable information (e.g., name, phone, email)
- Retail kiosks or in-store Wi-Fi showing device connections tied to loyalty accounts or previous login credentials
Data Linking
Advanced algorithms and machine learning match and link data from different sources to a single customer ID.
Examples of Matching Logic:
- Email Address Match: A logged-in web session and a mobile app session tied to the same email are linked.
- Phone Number Match: A customer calls a service center, and an SMS opt-in is associated with the same mobile number.
- Loyalty Program ID: In-store purchase and online shopping history linked through a unique loyalty account number.
- Account Login: Multiple devices and sessions are merged with a single authenticated account login.
- CRM Record Match: Offline sales rep interactions and digital campaign responses matched through a shared customer ID in the CRM.
- Device ID and Known User Tie-In: A mobile device used by a logged-in customer is remembered and matched in future sessions, as long as login credentials are shared.
Single Customer View
At the core of deterministic ID resolution is the creation of a Single Customer View (SCV)—a unified profile that aggregates a customer’s interactions, preferences, and behaviors into one cohesive record. This view enables enterprise brands to deliver consistent, personalized experiences at scale.
What is a Single Customer View (SCV)?
A Single Customer View is a centralized, continually updated profile that consolidates all known data about an individual across touchpoints. This includes demographic information, transaction history, engagement metrics, preferences, and more—structured in a way that’s accessible and actionable for marketing, sales, service, and analytics teams.
What Goes Into an SCV?
A well-constructed SCV typically includes:
- Identity Data: Name, email, phone number, loyalty ID, and other identifiers
- Demographic Data: Age, gender, location, household data
- Behavioral Data: Online data, such as browsing history, app usage, email engagement, and offline data like purchase frequency, in-store visits, customer service calls
- Transactional Data: Past purchases, order value, payment methods, returns
- Channel Preferences: Preferred communication channels (e.g., SMS vs. email), opt-in status
- Engagement History: Campaign response, content views, product affinities
It is important to note that brands must perform regular data hygiene and enrichment processes on their customer data to address incorrect or missing data. Identity solutions rely on clean, up-to-date data.
Deterministic and Probabilistic Identity Resolution: What’s the difference?
There are two main types of matching methodologies used in identity resolution: deterministic matching and probabilistic matching.
Deterministic identity resolution uses authenticated, offline data and high-fidelity matching to confidently connect online identifiers to real-world individuals and households. This process ties various data points—such as phone numbers and device IDs—to individual profiles without relying on predictive algorithms, ensuring identities are resolved at the highest levels of accuracy.
Since Deep Sync’s identity graph is built on offline, deterministic data, it enables accurate, reliable identity resolution and empowers businesses to target and engage customers more efficiently and effectively.
On the other hand, probabilistic identity resolution relies on predictive algorithms and heuristics to resolve customer identities to a likely match. Since these algorithms produce educated guesses based on the probabilistic data at hand, they have a wide margin of error and aren’t always accurate. Even small mistakes can result in inaccurate customer profiles and misdirected audience targeting.
Why Deterministic ID Resolution is Essential for SCV
Unlike probabilistic approaches, deterministic IDR ensures that every data point included in the SCV is tied to a verified individual. This significantly improves data reliability and compliance with privacy regulations, which is essential for enterprise brands dealing with high volumes of data and strict governance standards.
Does a Deterministic Approach Lead to Better Data Quality?
Yes! A deterministic approach is superior because it relies on personally identifiable, authenticated, or self-declared information instead of predictions based on patterns or behaviors.
Benefits of Deterministic Matching
A deterministic identity resolution solution can have many benefits for Enterprise Brands, including:
Unified Customer Profiles
Create a single, unified customer profile by linking disparate data points. This is also often called a singular customer record.
