--- title: "Belgium" url: "https://developer.incode.com/general-reference/belgium/" section: "general-reference" group: "eKYB Reference / eKYB Prefill Coverage" version: "v1.1" status: "live" --- # Belgium eKYB Prefill in Belgium leverages Belgium's source of truth to automatically retrieve and populate business information based on a company's BCE/KBO number or VAT number, including the business name, entity type, registration status, registration date, credit rating, and other corporate details, without requiring manual input from the user. ## Source | Country | Source | Description | | --- | --- | --- | | Belgium | `BE_KYB_PREFILL` | Returns matching Belgian business details from Belgium's source of truth for pre-fill. | ## Direct API approach For general integration notes and shared response semantics, see the [eKYB Prefill API Reference](/general-reference/ekyb-prefill-api-reference/). All module configurations and user data can be forwarded directly in the request for performing a Prefill lookup. This overrides existing configuration and data collected about the user. ### Endpoint `POST /omni/externalVerification/ekyb-prefill` ### Request parameters | Parameter | Required | Description | | --- | --- | --- | | `plugins` | Mandatory | String array. Must be `["ekyb-prefill"]`. Specifies the Prefill flow. | | `source` | Mandatory | String. Must be `BE_KYB_PREFILL`. Identifies the Prefill source. | | `country` | Mandatory | String. Two-letter Alpha-2 country code. Must be `BE`. | | `taxId` | Mandatory | String. BCE/KBO number or VAT number. See [Tax ID formats](#tax-id-formats) for details. | | `businessName` | Optional | String. Registered business name, used to verify the match against the source of truth. | | `address` | Optional | String. Business address, used to verify the match against the source of truth. | ### Tax ID formats Belgium supports two business identifier formats as search input. Requests with an invalid format return a 400 error. | Entity Type | Format | | --- | --- | | BCE/KBO number | 9 numeric digits, no prefix (e.g. `656908546`) | | VAT number | `BE0` + the same 9-digit BCE number (e.g. `BE0656908546`) | ### Sample request ```json { "plugins": ["ekyb-prefill"], "source": "BE_KYB_PREFILL", "country": "BE", "taxId": "656908546", "businessName": "", "address": "" } ``` ### Sample response The Prefill response returns business data retrieved directly from the source of truth. Passthrough fields are returned as-is from the source, without fuzzy matching or verification scoring. Match fields (`nameMatch`, `addressMatch`) are only returned when the corresponding input (`businessName`, `address`) was submitted. Field availability varies significantly by company — see the notes under each example below. **Example 1 — purchasing cooperative (large turnover, small headcount)** ```json { "kyb-prefill": [ { "tin": "123456789", "vatNo": "BE0123456789", "name": "SAMPLE TRADING CV", "nameMatch": "Verified", "address": "Sample Straat 10, 1040 Sample City", "city": "Sample City", "postalCode": "1040", "entityType": "Cooperative company", "registrationStatus": "ACTIVE", "registrationDate": "2016-06-22T00:00:00Z", "creditRating": "B", "creditRatingDescription": "Low Risk", "industryDesc": "Activities of business and employers membership organisations", "turnover": { "currency": "EUR", "value": 13390642077 }, "employeeCount": "39", "shareholders": [ { "name": "SAMPLE HOLDING SA", "percentSharesHeld": 32.67 } ], "directors": [ { "name": "SAMPLE DIRECTOR NAME", "positionName": "Director" } ], "otherAddresses": [ { "otherAddress": "Sample Straat 10 1040 Sample City" } ], "otherNames": [ { "name": "SAMPLE TRADING", "businessNameType": "Trading Name" } ] } ] } ``` **Example 2 — multinational subsidiary (cross-border parent)** ```json { "kyb-prefill": [ { "tin": "987654321", "vatNo": "BE0987654321", "name": "SAMPLE CHOCOLATE BELGIUM SA", "nameMatch": "Verified", "address": "Sample Dreve 13, 7700 Sample Town", "city": "Sample Town", "postalCode": "7700", "entityType": "Public limited company", "registrationStatus": "ACTIVE", "registrationDate": "1997-09-24T00:00:00Z", "industryDesc": "Wholesale of sugar, chocolate and sugar confectionery", "turnover": { "currency": "EUR", "value": 48835433 }, "employeeCount": "270", "websites": ["http://www.samplechocolate.example"], "shareholders": [ { "name": "SAMPLE HOLDING FRANCE SAS", "percentSharesHeld": 100 } ], "ultimateParent": { "name": "SAMPLE NETHERLANDS HOLDING B.V.", "country": "NL" }, "immediateParent": { "name": "SAMPLE NETHERLANDS HOLDING B.V.", "country": "NL" }, "otherAddresses": [ { "otherAddress": "Sample Dreve(L) 13 7700 Sample Town" }, { "otherAddress": "Sample Lei 37 2018 Sample City" } ], "otherNames": [ { "name": "SAMPLE CHOCOLATE BELGIUM NV", "businessNameType": "Trading Name" } ] } ] } ``` **Example 3 — small boutique with a distinct trading name** ```json { "kyb-prefill": [ { "tin": "456789123", "vatNo": "BE0456789123", "name": "SAMPLE BOUTIQUE BVBA", "nameMatch": "Verified", "address": "Sample Walletje 20 C, 8300 Sample Coast", "city": "Sample Coast", "postalCode": "8300", "entityType": "Private limited liability company", "registrationStatus": "ACTIVE", "registrationDate": "2010-07-30T00:00:00Z", "industryDesc": "Tour operator activities", "otherNames": [ { "name": "SAMPLE LUXURY BRAND BOUTIQUE", "businessNameType": "Trading Name" } ] } ] } ``` :::info Field availability differs significantly by company. `turnover`, `employeeCount`, `shareholders`, `directors`, `websites`, `otherAddresses`, and `creditRating` may all be absent for a given company — this is expected and does not indicate an error. `ultimateParent`/`immediateParent` are absent for companies that sit at the top of their own group. ::: ### Response fields | Key | Value | Description | | --- | --- | --- | | `tin` | BCE/KBO number | 9-digit registration number, as returned from the source of truth. | | `vatNo` | VAT number | `BE0` + the 9-digit BCE number. | | `name` | Business name | The registered legal name of the business as returned from the source of truth. | | `nameMatch` | Verified, Approximate Match, Unverified | Match result comparing the submitted `businessName` against the registered name.
