Overview of Indonesia's +62 811 Mobile Prefix
The +62 811 prefix is a non-geographic mobile network code assigned to mobile network operators (MNOs) and mobile virtual network operators (MVNOs) in Indonesia. Unlike geographic area codes, 811 does not correspond to a specific city or region; it is used for mobile services nationwide, including major islands such as Java, Sumatra, Kalimantan, Sulawesi, and Papua. This prefix is part of the Indonesian National Numbering Plan, which adheres to ITU-T E.164 standards.
Number Structure and Formatting
Indonesian mobile numbers using the 811 prefix have a total length of 9 to 10 digits after the country code, depending on the operator's allocation. The typical format is:
- International format: +62 811 XXXX XXX (or +62 811 XXXX XXXX)
- National format: 0811 XXXX XXX (or 0811 XXXX XXXX)
When dialing from abroad, you must replace the leading '0' with the country code +62. For example, a local number 0811-234-567 would be dialed as +62 811-234-567 from overseas. The exact number of digits may vary, but the total length of the subscriber number (including the prefix) is typically 10 to 11 digits in national format.
Carrier and Porting Considerations
The 811 prefix was historically associated with Telkomsel (specifically its Kartu Halo and simPATI brands), but due to mobile number portability (MNP) regulations, subscribers may retain their 811 number when switching operators. Therefore, the prefix does not guarantee a specific carrier. For accurate routing, always use the full number and rely on network databases for ported numbers.
Dialing Instructions
- Domestic calls: Dial 0811 followed by the subscriber number. No area code is needed.
- International calls: Dial your country's exit code (e.g., 00 from most countries, 011 from the US), then 62, then 811, then the subscriber number. Omit the leading '0'.
- SMS and MMS: Use the same international format for messages sent from abroad.
Regulatory and Usage Notes
The 811 prefix is allocated for public mobile services, including voice, SMS, and data. It is not a toll-free or premium rate number. Calls to 811 numbers are charged according to your mobile plan's rates for international calls or domestic mobile calls if you are in Indonesia. The prefix is also used for machine-to-machine (M2M) and IoT services in some allocations, but the general public uses it for standard mobile communication.
For businesses, having a mobile number with the 811 prefix can indicate a long-standing mobile service, but it does not provide any geographic advantages. When validating phone numbers for Indonesian customers, always check the full number length and consider that the subscriber may have ported to another network.
