Know Your Business (KYB)
The Know Your Business (KYB) module enables organizations to vet corporate entities before onboarding merchants, partners, or corporate customers. Prembly connects directly to official corporate registries, tax authorities, and anti-money laundering databases globally to retrieve authoritative company filings, verify active operating status, and unpack complex ownership structures.

2. Initiating a KYB Verification
Corporate verifications can be dispatched manually by compliance officers or automated via direct API integration and onboarding workflows.
Option A: In-App Dashboard Verification
When verifying an entity through the Prembly web app:
- Navigate to Products > Verification > KYB in the sidebar.
- Click Verify Business in the top right corner.
- Select the Country of Registration.
- Choose the target Verification Service (e.g., CAC Advanced, SCUML Verification, or Global Business Search).
- The modal dynamically displays the required fields defined in that service's schema (e.g., Nigerian CAC requires
rc_numberandcompany_type; Global Search requirescompany_numberand ISOcountry_code). - Click Run Check to execute the query against the official registry.


Option B: Verification Services REST API
Integrate corporate vetting directly into your merchant onboarding flow using the channel endpoints from the Verification Services Directory.
Example 1: Nigerian CAC Advanced Verification

X-API-Key: <your_api_key>
Content-Type: application/json

"country_code": "GB"
}Option C: Automated Workflows
Automate end-to-end corporate onboarding by designing pipelines in Workflows. You can configure a workflow to verify the corporate registry first, automatically extract the directors, and conditionally trigger identity and sanctions screening on each key executive.
3. Directors, UBOs & Chained KYC
A critical component of corporate due diligence is uncovering Ultimate Beneficial Owners (UBOs)—individuals holding 25% or more equity or significant managerial control.
- Automated Director Extraction: Advanced KYB endpoints return the full registry-declared list of officers, secretaries, directors, and major shareholders, including their full legal names, appointment dates, and registered addresses.
- Spawning Linked KYC: Inside the Directors & UBOs tab of any KYB report, compliance officers can click Run KYC next to any director's name. This triggers an individual identity check via Prembly's KYC module, automatically establishing a parent-child relationship between the business entity and the individual in Customer 360.
4. Reading the KYB Report & Verification Statuses
The KYB Report groups corporate telemetry into dedicated audit views:
- Company Overview: Legal business name, registration date, registered office address, and live registry status.
- Operating Status Flags: Highlights whether the company is actively trading (
Active) or poses compliance risk (Inactive,Dissolved,Struck Off, orUnder Receivership). - Directors & Shareholders: Complete ownership breakdown with action buttons to launch chained KYC or AML sanctions checks.
- Document Proofs: Digital certificates of incorporation, memorandum copies, or official filing status receipts when returned by the registry.
Response Status Codes
| Status Code | Label | Description | Recommended Handling |
|---|---|---|---|
00 | Success | Entity successfully retrieved from the corporate registry. | Review operating status and proceed to UBO vetting. |
01 | Not Found | Registration number or corporate name does not match registry records. | Prompt merchant to verify registration details or provide incorporation certificates. |
02 | Service Unavailable | Corporate registry database or government gateway is temporarily unavailable. | Retry with exponential backoff or place the check in an asynchronous queue. |
5. Compliance Management & Escalation
- Customer 360: Aggregates business registry data, merchant transaction metrics, and director risk profiles into a centralized corporate view.
- Case Management: If a corporate check reveals a dissolved status, high-risk sanctions flag, or unregistered business name, the record automatically routes into Case Management for senior compliance officer review.
- Audit Exports: Generate stamped compliance dossiers (PDF) or export verified corporate cohorts (CSV/XLSX) for regulatory submissions and banking partner audits.
