If you've landed on this Help Center directly from a search engine, here's some context on who we are. DQE Software is the company behind the APIs, connectors, and platform integrations documented in these pages.
Who is DQE Software?
DQE Software is an international software vendor specialising in customer data quality. For over 18 years, DQE has helped organisations validate, clean, deduplicate, and enrich customer data — postal addresses, email addresses, phone numbers, identities, and company (B2B) records — so that data stays accurate and usable across CRM, marketing, e-commerce, and compliance workflows.
DQE operates across Europe, China, and the United States. Its recent acquisition of Omikron combines complementary data quality expertise with strong coverage of the French and DACH markets, reinforcing DQE's position as a leading independent software vendor (ISV) in data quality.
DQE One: the product suite behind this documentation
DQE One is organised around three areas, several of which are documented in this Help Center:
- DataQ — real-time and batch validation covering addresses, emails, phone numbers, names, B2B company data, and mobile identity (ID Mobile).
- Unify — duplicate detection and merging for contacts, accounts, leads, and custom objects.
- Enrich — enrichment services such as geocoding and address relocation tracking.
These services are available as a standalone application, as native connectors for Salesforce and Microsoft Dynamics, or through APIs for custom integrations — which is what most of this Help Center covers.
Trusted by organisations worldwide
More than 1,000 companies across sectors such as luxury, banking, insurance, retail, and leisure rely on DQE to keep their customer data accurate, on projects ranging from single-record checks to processing tens of millions of contacts.
Technology and compliance
DQE's services are built to run in real time on a lightweight infrastructure. Data protection is built into the design — see our data processing description for details on how DQE handles personal data under GDPR. In 2026, DQE was awarded the EcoVadis Platinum medal, ranking among the top 1% of companies assessed by EcoVadis for corporate social responsibility.
