Introduction
In Bonaire, Sint Eustatius and Saba (the Caribbean Netherlands), tax administration and personal identification are managed by the Belastingdienst Caribisch Nederland (BCN). While there is no separate tax-specific TIN like in many other countries, residents receive a Citizen Service Number (BSN) and a CRIB number for tax filings and official interactions. All data here is verified against official BCN sources.
Tax Identification Number Types
- BSN (Burgerservicenummer): A 9digit citizen service number issued to residents for government and tax administration purposes.
- CRIB Number: A unique identifier issued by BCN for tax communications, payroll levies, and administrative processes. Used in lieu of a traditional TIN.
2. TIN Format and Structure
- BSN: A 9digit numeric code assigned to individuals (e.g., 123456789), no letters.
- CRIB Number: Numeric identifier of unspecified length used for tax filings and payroll; strictly numeric with no letters or separators.

Issuing Authority and Registration Process
The Belastingdienst Caribisch Nederland (BCN), part of the Dutch Tax Authority, issues BSNs and CRIB numbers. Residents receive a BSN via local registration, and CRIB numbers are issued for official interactions with BCN. Offices operate on Bonaire, Sint Eustatius, and Saba.
TIN Verification and Lookup
To verify a resident’s BSN or CRIB number, authorized parties should consult the BCN systems via the official Belastingdienst Caribisch Nederland portal. Access requires secured credentials or inperson visits to local BCN offices.

TIN and VAT Number Connection
Bonaire, Sint Eustatius, and Saba apply a General Expenditure Tax (GET) instead of VAT. Businesses registered for GET receive a unique GET number in the format 3XX.XXX.XXX (9 digits). That number is used for tax remittance and acts as the operational tax ID.
Why Accurate TIN Validation Matters
Accuracy of BSN, CRIB, or GET numbers is essential:
- Ensures correct processing of income tax, GET filings, and payroll levies.
- Prevents rejected filings, compliance errors, or audit issues.
- Supports secure onboarding of suppliers and payroll management.
