Telephone numbers in Singapore(Redirected from +65)
Telephone numbers in Singapore, also known as the National Numbering Plan, are regulated by the Info-communications Media Development Authority (IMDA). Due to the small geographical size of Singapore, there are no area or trunk codes, with the Public Switched Telephone Network, Radio Network and IP Telephony all belonging to one numbering area, and thus comes in the same 8-digit numbering format. Numbers are categorised based on the first digit, thus providing ten possible categories, of which six are currently in use and the remaining four reserved for future usage.
Location of Singapore
|Regulator||Info-communications Media Development Authority|
|Typical format||+65 XXXX XXXX|
|Country calling code||+65|

Until 1985, subscribers' telephone numbers in Singapore were five and six digits, but in that year, these changed to seven digits as the introduction of new towns arose (Tampines, Jurong East, Bukit Batok, Yishun and Hougang) and a large number of new numbers were required. Rationalisation was based on geographical locale over the 12 years.
In 1995, the digit '9' was added to the front of mobile phone and pager numbers, making numbers eight digits, and on 1 March 2002, the digit '6' was added to the front of existing fixed line telephone numbers.
Calls to Malaysia and Indonesian border townsEdit
Until 1995, calls to Malaysia from Singapore were direct, with only the area code and number being required, hence 03 for Kuala Lumpur instead of +60 3. In 1995, owing to the divergence of the two countries' numbering plans, the Subscriber Trunk Dialling prefix 020 was adopted. For example, in order to call a number in Kuala Lumpur, 020 is dialled first, followed by the area code 3 (excluding the leading zero), then the subscriber number.
Similarly, calls to Batam, Samarinda, Pekanbaru and Tanjung Pinang in Indonesia require only the code 011, followed by the area code (minus '0') and the subscriber's number, hence to call a number in Batam from Singapore, a subscriber would dial 011 778 xxx xxx, instead of the international code +62 778. Calls to the rest of Indonesia, including those to mobile phones, require international dialling.
Following the liberalization of the telecommunications industry, new carriers are assigned new carrier-specific codes for international and regional trunk call services. The codes 020 and 011 are assigned to the incumbent carrier SingTel. The other two major carriers, M1 and StarHub, do not offer any special dialling arrangements for calling to Malaysia and Indonesia, instead requiring full international dialling, the same as calling other countries.

International Direct Dialling and VoIP servicesEdit
The generic international call prefix when making an international call is 000, which all telecommunications service providers are required to share. However, the code is not well known as carrier-specific access codes are generally used, such as 001 for SingTel, 002 for M1 and 008 for StarHub. On a mobile phone, a plus sign (+) can be keyed in as a substitute for the prefix.
VoIP services, like Zone 1511, use prefixes in the 15xx range. For example, to call a number in London using Zone 1511, a subscriber would dial 1511 44 20 xxxx xxxx. hhAccess codes in the 0xx range (for example, 018 - StarHub's VoIP services or 019 - SingTel's VoIP services) indicate a Tier 1 VoIP provider. Access codes like 1xxx (for example, 1511) are indicative of a Tier 2 VoIP provider.
