Singapore Residential Number

Singapore Residential Number

The Info-communications media Developer Authority (IMDA), is responsible for regulating telephone numbers in Singapore. Also known under the National Numbering Plan. Singapore doesn’t have either area codes or trunk codes. A Wholesales VoIP is services of area code for the business sector 417 area code and 469 area code.


Prior to 1985 in Singapore, subscribers’ numbers consisted of five-digit and six-digit numbers. In the 1960s, 6-digit and 5digit numbers were introduced. Fixed lines grew in number and changed to seven-digit numbers in 1962. This was due in part to the emergence or new towns, such as Tampines and Jurong East, Bukit Batokok, and Yishun. A large number of numbers were required.


On September 1, 1995 the digit 9 was added to mobile phone and pager numbers. This gave rise to eight digits in numbers. After the April 2000 liberalization in telecommunications, the market saw rapid growth. This resulted to an increase in demand. SingTel StarHub, StarHub, and StarHub were all public telecommunications service provider. A way to minimize disruption to service was needed. They used the 8-digit system to ensure customers had seamless service continuity after the migration. After 30 June, all calls to Indonesian/Malaysian border towns will be cut off.


Singaporeans could call Malaysia directly from Singapore. This was similar to domestic calls. The only difference between calls to Malaysia from Singapore was that either the area code of the mobile phone or fixed line were required. For example, 019 for Celcom mobile phone carrier and 03 for Kuala Lumpur fixed telephone line. The area code (3, excluding any leading zero) is then followed. Finally, enter the subscriber Prepaid Mall and Lets Dial.

  • Similar to calls made to Samarinda in Indonesia and Batam, the 011 code must be followed the area code (minus “0”) and subscriber’s number. To call Batam in Singapore, the subscriber would dial 011-778xxxxxx instead.
  • Singapore phone numbers are written as +65XXXXXXXXXXYYY/+65XXXXXXXYYY. While landline numbers start from 6 and VOIP with 3, respectively, subscriber numbers are 8 numbers. There are no areas codes.
