Curaçao Phone Number validator
How the phone number format works
- Format
- Curaçao phone number in national or international (+599) format
- Example
- +59995181234
Things to watch for
- Accepts national or international (E.164, e.g. +599...) format
- Validated with Google's libphonenumber; confirms the number is possible/valid for this country, not that it is currently assigned or reachable
^[+]?[0-9 ()\-]{6,}$A Curaçao phone number is 8 digits under the shared code +599 — mobile numbers typically start with 9, landlines with 4 or 5. Curaçao became a separate, self-governing country within the Kingdom of the Netherlands in October 2010, when the former Netherlands Antilles was formally dissolved, and it kept the old +599 code rather than being assigned a new one of its own — a legacy it now shares with the smaller Caribbean Netherlands islands of Bonaire, Sint Eustatius, and Saba.
How this validator works
Enter the number in national form (95181234) or full international form (+59995181234); this tool checks the 8-digit length and leading-digit pattern against Curaçao’s real numbering plan using Google’s libphonenumber, entirely client-side. Because +599 covers four separate islands, the digits after the country code — not the country code itself — are what actually distinguish a Curaçao number from a Bonaire one; the validator checks the full sequence against Curaçao’s specific ranges rather than the code alone.
What a pass doesn’t tell you
A pass confirms the digits form a real Curaçao number shape — it doesn’t confirm the SIM is active or the landline connected, a separate carrier-side question this tool doesn’t try to answer.
Scope: useful for catching a digit mismatch within the shared +599 plan before a Curaçao number reaches a form — not a substitute for a real lookup service.

phone number FAQ
Does Curaçao share its country code with other islands?
Yes. Curaçao and the three islands of the Caribbean Netherlands — Bonaire, Sint Eustatius, and Saba — all still carry +599, inherited from the former Netherlands Antilles, and are told apart only by different leading digit blocks after the country code rather than by separate codes of their own.
Why does Curaçao show up so often in online casino licensing?
Curaçao has run one of the world's longest-established offshore gambling licensing regimes, making a Curaçao contact number a common sight on online casino and gaming-operator sites, alongside its more conventional financial-services sector.
Does a valid check confirm a Curaçao number is currently active?
No. It only confirms the 8 digits match a real Curaçao numbering pattern — not that the SIM is active or the landline connected, which needs a carrier-side lookup this free tool doesn't perform.
