Caller Instructions

• Local callers within Kalka: If you are calling from within the same STD code area, you may be able to dial only the 7-digit subscriber number, depending on your telephone exchange. However, for clarity and consistency, it is recommended to use the full STD code format.
• Callers from other parts of India: Always prefix the number with '0' before the area code. For instance, to call a Kalka number from Mumbai, you would dial: 0-1733-XXXXXXX.
• Callers from abroad: Dial your country's international access code (e.g., 011 from the US, 00 from most European countries), followed by India's country code 91, then the area code without the leading '0', and finally the subscriber number. Example: 011-91-1733-XXXXXXX.

Overlay and Numbering Considerations

Currently, there is no overlay code for the Kalka area. The 1733 code is exclusively assigned to this geographic region. As per the Telecom Regulatory Authority of India (TRAI) guidelines, the number of digits in the subscriber number is fixed at 7 for this area, making the total length of a local number (including the area code) 11 digits (excluding the trunk prefix).

Network and Services

Landline services in Kalka are primarily provided by state-owned BSNL (Bharat Sanchar Nigam Limited) and private operators like Airtel and Reliance Jio, which offer fixed-line services in select areas. These lines are part of the public switched telephone network (PSTN) and support traditional voice calls, fax, and DSL broadband services. Mobile services in the region use separate mobile prefixes and are not covered under this geographic code.

When dialing from abroad, ensure you have the correct country code and area code to avoid misrouted calls. For any billing or tariff inquiries, contact your service provider.
