1 March 2002: wireline subscriber numbers change to 8 digits

Conventional telephone numbers (fixed, wireline services) in Singapore expanded to 8 digits as of 1 March 2002. The digit '6' was prepended to the existing 7-digit subscriber numbers.

The Infocommunications Development Authority of Singapore (IDA) moved the expansion date forward from a previous March 2004 target date. Previous reports also indicated a 2003-2004 time range.

Within Singapore, the permissive dialling period will be for the month of March 2002, where both 7-digit and 8-digit numbers can be used. As of 1 April 2002, attempts to use 7-digit numbers will not reach a subscriber but rather a recorded announcement. After 30 June 2002, this recorded announcement will be replaced by a service unavailable tone.

From other nations, the permissive dialling period was from 1 March 2002 through 31 August 2002. After that date, international callers attempting to use 7-digit numbers heard a recorded announcement, without reaching a subscriber. The end of permissive dialling period was moved up from a previously announced 28 February 2003 deadline. The recorded announcement was removed at 1 March 2003, with old dialling format resulting in an unavailable number response.

Wireless numbers (mobile, paging) that begin with the digit '9' are not affected by this change. These were already 8-digit numbers as of 1995 (see below).

For details on this change, see IDA Media Release of 19 January 2001.

KDDI announcement of 2001.

Singapore telecom regulator TAS previously announced its intention to expand the wireline subscriber numbers. See TAS announcement for an earlier document on the numbering expansion.

Wireless numbers (cellular, pager) were already expanded to 8 digits (see below).

1995-1996: 020 access code to Malaysia introduced

Prior to 1995-1996, 020 was a prefix to call Malaysia +60 numbers from Singapore.

Details courtesy Ken Westmoreland:

"Some time during 1995-1996, direct dialling to Malaysia was discontinued, as a result of that country's introduction of the 01 range for mobile phone services. Instead of using the +60 country code, the prefix 020 was introduced for trunk dialling to Malaysia."

1 September 1995: renumbering of wireless services

8-digit numbers were in effect for mobile phones and pagers as of 1 September 1995, with 9 added before the previous 7-digit mobile number (source: Singtel).
