Dial CodesHow to call San Marino from India
- Dial 00, the exit code of India. On a mobile phone you can press and hold 0 to type + instead.
- Dial 378, the country code of San Marino.
- Dial the rest of the number. Numbers in San Marino have no trunk prefix, so dial every digit of the number as it is written.
So a mobile number shaped like +378 6X XX XX XX is dialled from an Indian landline as 00 378 6X XX XX XX, and from any mobile phone as +378 6X XX XX XX. The X marks stand for the digits of the real number.
How to call San Marino from other countries
The steps are the same everywhere: your own country's exit code, then 378, then the number. The exit code is 011 from the United States and Canada, 00 from most of Europe, Africa and Asia, and 0011 from Australia. A mobile phone accepts + in place of any exit code, which is why numbers are best saved as +378 followed by the number.
