Deep Sync’s Identity Resolution Services

Transform fragmented data collected across multiple sources into single customer views—centralized, continually updated profiles that consolidate all known data about individuals across touchpoints—with our identity resolution services.

Advanced algorithms leverage our exclusive identity graph to link disparate data to persistent IDs.

    Identity resolution assembles disparate identifiers to construct a comprehensive understanding of your customers.

    By connecting fragmented data points with Deep Sync’s persistent individual identifier, identity resolution creates cohesive customer profiles essential for accurate marketing, engagement, and measurement. In addition to the application of our individual identifier, Deep Sync provides:

    • Address standardization
    • Change of address processing
    • Deduplication

    Access actionable insights about your customers with Deep Sync’s Identity Resolution service.

    Data translation enables seamless activation and utilization of customer data across channels and platforms. By bridging the gap between offline and online data points, translation clarifies the customer journey while providing the means to extend your reach and continue the conversation.

    Available offline data points include:

    • First Names
    • Last Names
    • Postal Addresses
    • Email Addresses
    • Phone Numbers

    Available online identifiers include:

    • CTV IDs
    • IP Addresses
    • MAIDs
    • UID2s

    Bridge the gap with Deep Sync’s data translation service.

    Identity Resolution FAQs

    How does identity resolution work?

    The identity resolution process starts when you share your first-party customer data with Deep Sync. Alternatively, you can use our Integrated Identity Resolution application in the Snowflake marketplace to complete the process in the cloud.

    Whichever method you choose, Deep Sync uses a deterministic matching process to attribute various identifiers to your customers. Equipped with our identity graph and exclusive persistent identifier, the Deep Sync ID, we link offline and online data, ultimately resolving your records to unified customer profiles.

    What is a persistent identifier?

    A persistent identifier is a unique code assigned to an individual or household. Even if a customer changes their physical address, email address, or phone number, this ID remains the same. As a result, you can continuously group customer data and understand each individual’s customer journey despite any changes to their personal information that might otherwise make them more difficult to track.

    How does identity resolution improve my marketing ROI?

    Identity resolution improves your marketing ROI by:

    • Delivering more relevant communications. When you centralize customer data into unique profiles, you can personalize your marketing messages to each individual’s needs, encouraging brand loyalty.
    • Avoiding fragmented messaging. Identity resolution empowers you to serve cohesive messages across channels rather than disjointed ones, creating cross-channel consistency and reinforcing key points.
    • Reducing customer acquisition costs. Marketing campaigns that speak to customers’ unique needs and provide cohesive messaging cultivate a positive customer experience that encourages them to stick around. By retaining these customers, you won’t have to spend as much on customer acquisition.

    How often is your identity graph updated?

    Our deterministic identity graph is updated weekly. These regular updates ensure we’re resolving customer identities using the most accurate, up-to-date information possible.

    Is your identity resolution process privacy-compliant?

    Yes, Deep Sync is committed to privacy and compliance across its data solutions. We meet, if not exceed, all applicable consumer privacy requirements, accept opt-outs from every state, and never sell or share your proprietary customer files. If you’d like to keep your data secure in the cloud, we can perform identity resolution through our Integrated Identity Resolution application in the Snowflake marketplace.

    Additionally, the persistent Deep Sync ID assigned to each customer is completely anonymous. We store offline data separately from online data and link this information to pseudonymized individual IDs.

    Identity resolution as a whole actually helps you strengthen your compliance with privacy regulations. For instance, if a customer opts out of communications on one device, identity resolution can help ensure you honor that request across their devices.
