* There are no city codes in some countries. In such case, you need to dial the phone number right after the country code.

To call a subscriber in San Francisco (USA), you need to dial:
0 – 0 – 1 – 415 – XXXXXXX, where
0 – 0 – international exit;
1 – USA country code;
415 – San Francisco code; XXXXXXX – phone number of the subscriber.

To call to a subscriber in Odesa, you need to dial:

If you are making a call within one area of Ukraine, except for the Kyiv region, instead of an area code you need to dial “2” and the city code (two figures), then, without any interval, you need to dial the phone number of the subscriber.
For making long-distance calls to a subscriber in the Kyiv region, you need to dial “0”, wait for the continuous signal, dial area code “45” and the city code (two figures), then, without any interval, you need to dial the phone number of the subscriber. The same order follows making a call between subscribers within the Kyiv region.
