Caribbean Netherlands phone number format

How do you format a Caribbean Netherlands phone number?

Write a Caribbean Netherlands phone number with the country code +599. A mobile looks like 318 1234 inside the Caribbean Netherlands and +599 318 1234 from abroad. Mobiles have 7 digits after the country code, and the E.164 form is +5993181234. A format check confirms the digits fit the numbering plan, not that the number is in service.

These are the example numbers from Google’s libphonenumber data, the same numbering-plan data our validator uses, written three ways.

How to write a Caribbean Netherlands number in E.164

1. Remove spaces, dashes, dots and brackets so only digits are left.
2. The Caribbean Netherlands has no trunk prefix, so keep every digit of the national number.
3. Put +599 in front. The result has 7 digits after the country code for a mobile.

So 318 1234 becomes +5993181234. E.164 is the format SMS gateways, dialers and most CRMs store; see the E.164 format explained for why.

Mobile or landline?

The Caribbean Netherlands allocates separate number ranges to mobiles and landlines, so a numbering-plan check reads the line type straight from the digits, for free. That type describes the range the number came from. It doesn’t prove the number is connected today.
