Get a complete profile of individuals by identifying and connecting crucial pieces of information
Stop marketing to fragmented profiles. Alesco’s Identity Resolution services break down data silos, linking disparate offline identifiers — like postal addresses and phone numbers — to digital IDs, giving you a single, unified view of your customer.
At the heart of our resolution service is our identity graph. We continuously ingest, validate, and reconcile multiple B2B and consumer data points from trusted public records, utility connections, and digital signals. This powerful engine matches your fragmented first-party data against our premier databases, resolving multiple device IDs, emails, and physical addresses back to a single, real-world individual.

Automatically append missing phone numbers, email addresses, and physical addresses to complete your CRM profiles.

Seamlessly bridge the offline-to-online gap. Onboard your direct mail lists directly into programmatic DSPs and social platforms with high match rates.

Track the true customer journey by understanding when a digital ad impression, an email open, and a physical mail piece hit the same household.

Build a durable marketing foundation independent of third-party cookies by relying on privacy-compliant, persistent first-party identifiers.

As part of the process, we gather data from various sources, which may include databases, spreadsheets, web forms, or external data providers. We then clean and standardize the data to remove inconsistencies and errors, such as formatting and misspellings.

With matching, we compare the data elements to identify potential matches. We use various algorithms and techniques, such as exact, fuzzy, or probabilistic matching.

Scoring involves assigning a confidence score to each potential match to indicate the likelihood that two records refer to the same entity. The threshold for accepting a match can be adjusted based on the desired level of accuracy and recall.

Establishing links or connections between records that meet the matching criteria, we effectively merge or consolidate them into a single entity or profile. We then resolve any conflicts or inconsistencies during the linking process, such as differences in attributes or values.
Email is a critical aspect of data integration that involves identifying and associating an individual’s multiple email addresses across various platforms and databases. By accurately connecting these existing accounts, businesses can better understand customer behavior, enhance marketing strategies, and create personalized user experiences. With email identity resolution, organizations can achieve higher email deliverability rates and optimize their marketing efforts effectively.


IP Identity Resolution revolves around matching and consolidating multiple IP addresses that an individual uses across devices and networks. This process helps businesses in fraud detection, security enhancement, and targeted advertising. Companies can detect suspicious activities and prevent unauthorized access while delivering relevant content to specific IP address segments.
This type of identity resolution focuses on linking various phone numbers associated with an individual to build a unified profile. It enables businesses to establish seamless communication with customers and prospects, improve service, and carry out effective marketing campaigns through targeted SMS or phone calls. Companies can also enhance lead generation and optimize their outreach strategies.


This identity resolution component connects multiple physical addresses attributed to a single person. This is vital for companies with extensive direct mail marketing initiatives or those that rely on accurate customer location data for their services. By resolving postal identities, businesses can minimize communication redundancies and ensure the successful delivery of physical marketing materials.
An identity graph is a database that links different identifiers associated with the same person or household. Alesco’s graph matches anonymous digital signals (like IP addresses or mobile ad IDS) with verified offline data (like physical addresses) to create a single, cohesive view of a prospect.
