Is 1800 Free Call In Singapore

The InfocommunicationsMediaDevelopment Agency (IMDA), controls the phone numbers in Singapore. Singapore does not have any area numbers or trunk codes. Every number is assigned to the same area and so are all 8-digit numbers. Ten possible categories exist, six are currently in use, the rest will be used in the future.


Before 1985 subscribers’ phones numbers in Singapore were between five- and six-digits. In the 1960s, fixed line growth led to 5-digit and 6-digit numbers being introduced. These numbers were then changed to seven digits due to the emergence in new places like Tampine (Tampines), Jurong East or Bukit batok.

The digit 9″ was added to pager numbers and mobile phone numbers. Numbers now have 8 numbers. The number eight has been added to the frontline of fixed-line telephone numbers on the 1st March 2002. SingTel was the public provider of telecommunications services by Prepaid Mall and Lets Dial
