Public resources The emergency number is 112. GSM mobile phones may accept different numbers, such as 999, 000 or 911, depending on the firmware. Additionally, calls to 911 are forwarded to 112 (in the Caribbean Netherlands, this is reversed - 112 redirects to 911 in that case). Directory assistance is available from several commercial providers, on 18xx (e.g., 1888 from KPN). Caribbean Netherlands The islands of Bonaire, Sint Eustatius and Saba, which form the Caribbean Netherlands after the dissolution of the Netherlands Antilles, retained the numbering plan of the Netherlands Antilles using country code +599, followed by 7, 3 or 4 for Bonaire, Sint Eustatius or Saba, respectively. Calls between the European Netherlands and Caribbean Netherlands are billed as international calls.
