CDQ Guards
What Address Guard does
One API that keeps every business partner address correct, complete, and consistently formatted — at the point of entry and over time.
Address cleansing & enrichment
Corrects misspellings, outdated postal codes, and incomplete components, then standardizes formats to ISO standards and regional conventions like France's CEDEX. Enriches from external reference data or purely from internal metadata when external queries aren't needed.
Address autocomplete
Delivers smart, real-time address suggestions as users type — after as few as three characters — returning structured components plus a CDQ-ID, so addresses are complete and standardized right at onboarding.
Geo-coordinate enrichment
Converts addresses into geographic coordinates for deliveries, field operations, and analytics, with both geocoding and reverse geocoding. The step is optional in metadata-only mode.
Address & location identifiers
Enriches records with globally recognized identifiers — Swiss EGID, What3Words, Google Plus Codes, and UN/LOCODEs — using fuzzy and strict matching, especially where formal addressing systems are sparse or missing.
Address Data Pool
Integrates authoritative reference data from commercial, governmental, and open-source providers — Google Maps, HERE, USPS, OpenStreetMap, GeoNames, Wikidata, ePost Korea — plus internal CDQ metadata, so you get up-to-date reference data without managing sources.
Traceable, network-enhanced data
Every address change is traceable to its source and detection date. Through the CDQ network, you benefit from shared, network-enhanced reference data that fills gaps and speeds updates in regions with limited public data.
Why CDQ Address Guard
Four reasons enterprises choose Address Guard over one-off tools.
Continuous, not one-off
One-off cleansing projects go stale fast. Address Guard maintains address quality over time through an automated, continuous process.
Truly global coverage
Localized tools can't handle global diversity. Address Guard applies local and global formatting rules with per-region config and authoritative sources across jurisdictions.
Authoritative + network data
Manual validation doesn't scale. Address Guard validates against authoritative postal and reference sources, and its Data Pool fills gaps where public data is limited.
Embedded in your workflows
Delivered as headless APIs that plug cleansing and enrichment into ERP, CRM, and MDM — and works alongside other CDQ Guards.
How Address Guard works
A single API call turns a raw, inconsistent address into a clean, enriched, and traceable record.
Reference address identification
The system matches your input address against connected sources such as Google Maps, HERE, or local postal authorities — or works purely from internal metadata when external data is unavailable or unnecessary.
Enrichment and harmonization
Missing components — localities, administrative areas, postal codes, PO Boxes, premises, thoroughfares — are added and harmonized to ISO standards and regional conventions for consistent formatting across datasets.
Geo-coordinate enrichment
Where geospatial data is needed, addresses are converted into geographic coordinates via external geocoding services. This step is optional in metadata-only mode.
Translation and normalization
Addresses can be translated to a target language (English by default) and normalized to predefined standards, such as Latin characters without accents, for consistency across systems.
Location identifier enrichment
Records are enriched with identifiers like Google Plus Code, What3Words, EGID, or UN/LOCODE, using strict and fuzzy matching for precise, communicable location references.
Address Guard, answered
What master-data, compliance, procurement, and integration teams ask before a demo.
What is Address Guard?
Address Guard is a CDQ Guard that continuously cleanses, standardizes, enriches, and geo-standardizes business partner address data via API. It corrects and formats addresses to local and global conventions, fills in missing details such as postal codes and geo-coordinates, and validates them against authoritative postal and reference sources — so every address in your systems stays correct, complete, and usable.
Who is it for?
Master-data and governance leads who need consistent, harmonized formats and audit trails; risk and compliance teams validating addresses for KYC, tax, and ESG; procurement and finance teams cutting delivery and invoicing errors; and analytics and IT teams that need AI-ready, standardized data and headless APIs. It's built for large multinationals dealing with diverse global address formats.
How does it integrate with SAP, CRM, and MDM?
Address Guard is delivered as headless APIs that embed cleansing and enrichment directly into ERP, CRM, and MDM workflows — including SAP MDG — rather than as a standalone tool. It returns standardized outputs to reduce integration complexity, and works alongside other CDQ Guards like Partner Guard and Data Quality Guard.
How is data controlled and kept secure?
CDQ operates on a secure, customer-specific Data Mirror. Insights are proposed, never enforced — you keep full control of what's applied. Every change is traceable to its source and detection date, and anonymized improvements are only shared across the CDQ network with your consent.
Why continuous rather than a one-off cleanup?
One-off address cleansing projects go stale quickly. Address Guard defines a continuous category — automated cleansing, enrichment, and geo-standardization that maintains address quality over time and validates against authoritative sources, so quality doesn't decay between projects.
