Also known as: Acxiom ID, Acxiom Real Identity ID
Vendor-managed persistent consumer identifiers used to resolve and link identities across channels, devices, and datasets.
DESCRIPTION
Acxiom Consumer IDs are proprietary, privacy-aware identifiers that unify disparate consumer signals into persistent, person-level identities. They enable marketers and data teams to recognize individuals across offline and online channels, support audience building, measurement, and suppression, and reduce duplication. The IDs typically combine deterministic and probabilistic matching while honoring consent and regional privacy requirements. They underpin use cases like onboarding CRM audiences, attribution, and personalization, and integrate with adtech/martech platforms and clean rooms. Governance and contract controls are vital to ensure compliant usage and minimize re-identification risks.

TOP QUESTIONS
What are Acxiom Consumer IDs used for?
They unify consumer signals into a persistent ID to enable audience building, activation, measurement, and suppression across channels. The goal is consistent recognition that respects consent and privacy.
Category: Usage
How do Acxiom Consumer IDs relate to identity resolution?
They are outputs of identity resolution, linking identifiers such as hashed emails, device IDs, and postal addresses into a single person-level identity graph.
Category: Concept
What data privacy considerations apply to Acxiom Consumer IDs?
Use must align with consent, contractual restrictions, and regulations like GDPR and CCPA. Data minimization, retention, and purpose limitation are core controls.
Category: Risk
How are Acxiom Consumer IDs integrated into a data stack?
They are delivered via files, APIs, or platform connectors and mapped to first-party keys in warehouses, CDPs, or clean rooms for analytics and activation.
Category: Implementation
What matching methods underpin Acxiom Consumer IDs?
They commonly combine deterministic matches (e.g., hashed email) with probabilistic signals (e.g., co-occurrence patterns), weighted by quality and recency.
Category: Methods
How do Acxiom Consumer IDs compare to Experian Consumer IDs?
Both are vendor-managed identity graphs; differences include graph scale, partner ecosystems, coverage by region or channel, and pricing or contractual terms.
Category: Alternatives
How do I measure the quality of Acxiom Consumer IDs?
Track match rate, precision/recall on known holdouts, household vs. person disambiguation accuracy, decay over time, and impact on campaign performance.
Category: Validation
Can Acxiom Consumer IDs be used in clean rooms?
Yes, they are often supported in privacy-preserving clean rooms to enable overlap analysis and activation without exposing raw identifiers.
Category: Architecture
What is a common mistake with Acxiom Consumer IDs?
Assuming persistence equals truth; identities drift. Ongoing governance, versioning, and recertification are needed to prevent stale or over-linked records.
