Area code information

30 September 2011 - Sint Maarten changes to +1 721

Sint Maarten will transition to the North American Numbering Plan (+1) where it would leave +599 and migrate its numbers to +1 721 xxxxxxx.

+1 721 will be activated in permissive mode on 30 September 2011 (previously planned for 31 May 2010), allowing calls to St Maarten using the existing +599 numbers until 31 March 2012 (previous plan mandatory date was 30 November 2010). After use of +1 721 becomes mandatory, a recorded announcement would be provided to callers attempting to dial St Maarten with +599 until at least 31 March 2013 (30 November 2011 in previous schedule).

Approval was granted after review by the NANP Industry Numbering Committee from 2008. There was an industry suggestion to consider sharing an area code with one or more other island nations for this case (ATIS, INC101 12-21 August 2008).

There were no details as of June 2011 regarding changes to short codes and international prefixes, if any, with the transition to +1 721. Existing calls to St Martin (French portion of the island) are placed using the international prefix and country code +590.

10 October 2010 - dissolution of Netherlands Antilles

The Netherlands Antilles was dissolved on 10 October 2010 (previously scheduled for 1 January 2010). Sint Maarten formed an autonomous government under the Netherlands while Bonaire, Saba and Saint Eustace became special island municipalities of the Netherlands. In 2009, Curaçao became a constituent state.

Aruba split from the Netherlands Antilles in 1986 and was assigned its own country code, +297.

July 2004 - area codes formally absorbed for most islands

Telephone numbers for the islands of Bonaire (+599 7), Saba (+599 4), St Eustatius (+599 3) and St Maarten (+599 5) were formally declared national numbers with the former area codes absorbed into the subscriber numbers.

Area code format remained in effect for Curaçao (+599 2, +599 6, +599 8, +599 9).

20 April 2004 - St Maarten area code eliminated

Regulator Burtel confirmed numbering changes for the island of St Maarten, which eliminated the area code '5' (former format +592 5 xxxxx) and integrated the digit into the subscriber number (new format +592 5xxxxx or +592 5xxxxxx).

Subscriber numbers will be 6 or 7 digits long, depending on range and service. Collect and operator-assisted calls to St Maarten were only allowed for the +592 54xxxxx fixed/wireline number range.

The announcement indicated that the island of Curaçao continues to structure its numbers with area codes (+592 2, +592 6, +592 8, +592 9).

1997-2001 (?) - national 7-digit subscriber numbering plan

Netherlands Antilles has completed a transition to a national 7-digit numbering plan. Area codes as such were eliminated, except for Curacao which retains area code 9 (+599 9) before the 7-digit subscriber number.

Calls from one island to another reportedly still require use of the trunk prefix 0. Local calls within an island apparently require 7-digit dialling.

Some details were available in a document from the telecom regulator as filed with ITU as of September 2000 (page no longer available).

Information on Numbering Plan (as of 1st July 2000) is also available on a Cyserve page.

However, there have been conflicting reports and unclear information among various sources as to timing and details of the various changes.

Some details are also confirmed in a report courtesy Greg Monti (December 2002).

The following table indicates the migration from former to current number formats, according to island and service type, based on consensus of available information:

Island        Old Format       New Format      Service/Carrier

2000? - St Eustatius - change to national 7-digit format

According to information filed with ITU in September 2000, numbers in St. Eustatius (Statia) had been converted from the previous +599 3 8xxxx format to the national 7-digit format +599 318xxxx.

The exact date of the St Eustatius change is unknown.

The area code was eliminated, and '31' prepended to the subscriber number to form the new national 7-digit number.

Examples of the new 318xxxx format numbering have been found on various sources.

before July 2000 - Saba changes from 5 to 7 digits

Saba was reportedly converted to 7-digit format of 416xxxx (formerly in the format +599 4 6xxxx) just before July 2000.

According to information filed with ITU in September 2000, the conversion was as follows:

Fixed/wireline subscriber numbers of form +599 4 62xxx and +599 4 63xxx were changed to +599 4162xxx and +599 4163xxx respectively.

Mobile numbers of form +599 4 65xxx were changed to +599 4165xxx.

Item on the phone number changes: article on www.seasaba.com.

1999-2001 (?) - Sint Maarten subscriber number expansion (+599 5)

Sint Maarten (+599-5) was converted from 5-digit to 7-digit subscriber numbers by 2001.

Eastern Caribbean Cellular (ECC) reported that cellphone reprogramming would be required from 9 April 2001 to 14 May 2001, by prepending digit '5' to ECC and TelCell 6-digit numbers. The existing 6-digit format for cellphones was reported to be temporary, in preparation for eventual completion of transition to 7-digit numbering throughout the Netherlands Antilles. All mobile phones in St. Maarten would be 7 digits as 14 May 2001.

Source: Daily Herald article.

Information filed with ITU in September 2000 indicated that fixed/wireline telephones were already functioning as 7-digit numbers for the ranges +599 52xxxxx and +599 54xxxxx.

Greg Monti reported (December 2002) that the former +599 5 xxxxx format was converted to +599 54xxxxx (prepend '54' to subscriber number, and eliminate the area code).

According to an earlier article in the Daily Herald, the digits '52' were to be prepended to existing 5-digit subscriber numbers to form new 7-digit numbers. This was a change from an even earlier plan to prepend the digits '46' before Sint Maarten subscriber numbers. The new 7-digit Netherlands Antilles plan will be compatible with the North American Numbering Plan, of which there are rumours about joining.

An early report of this was received from John Boteler.

JMB mentioned a plan to expand from 5 to 6 digits, by prepending the digit '2', although that plan was obviously abandoned or unconfirmed. (tip courtesy Ray Chow)

18 October 1999 - Bonaire subscriber number expansion (+599 7)

As of 18 October 1999, Bonaire subscriber numbers were expanded to 7 digits from 4 digits, and the area code digit (7) incorporated into the subscriber number. International calls to Bonaire should now be dialled as +599 then the new 7-digit format.

Source: Info Bonaire.

Within Bonaire, a prefix 717 was added to the previous 4-digit non-wireless subscriber numbers. If the old number was 2345, the number after 18 October 1999 would be 717.2345.

From abroad, the first 7 of the 717 prefix signifies Bonaire island. But area codes as such have been eliminated in the Netherlands Antilles. International calls to 2345 in Bonaire are now dialed as +599 717 2345 (formerly +599 7 2345).

According to information filed with ITU in September 2000, Bonaire mobile number ranges are +599 78xxxxx and +599 79xxxxx.

See also Bonaire E-News (September 1999) for another report on Bonaire changes.

Previous reports originally announced various subscriber number expansion lengths: 5, 6 or 7 digits from 4. Earlier reports are available from: Info Bonaire, and Bonaire E-News (June 1999).

An early news report on the change claimed that the first digit of the prefix to be added to Bonaire subscriber numbers was practically guaranteed to be '3', to allow for a transitional period between old and new numbering plans.

Bonaire cell numbers were to be moved from the Curacao numbering range (+599 9) into Bonaire's range (+599 7) when this change takes effect. Confirmation of change dates was unavailable, but Cyserve reports that Telbo Cellular numbers will be of the form 78xxxxx, while Cellular One subscriber numbers are of format 79xxxxx.

1 February 1997 (?) - Curacao subscriber number expansion

An extra digit was added to Curacao numbers (previously in the +599 9 xxxxxx format) in 1997. 7-digit numbers were formed from previously 6-digit numbers. The area code digit '9' was retained, therefore the format became +599 9 xxxxxxx (with +599 9 before the 7-digit subscriber number).

An information article is available. (Thanks to a reader whose tip led to more details on this change.)
