The Nikolian telephone numbering plan is a telephone number assigning system used in Nikolia. All numbers (both fixed and mobile lines) have 8 digits, with only difference being that mobile lines calling codes have three digits, compared to four within fixed lines. Area code can be omitted when the caller and the receiver are in the same area. This, however does not apply to mobile lines.
Since 1965, Nikolia uses 8 digit system with 4 digit area code for landlines and 3 digit dialing code for mobile service providers. Area codes are assigned based on voivodeships and counties. Standard area code format is
VVCC whereas the first two digits are voivodeship network group, for instance numbers registered in Moravia would have
67 as the two digits of the dialing code. The remaining two digits are county network groups, assigned per administrative divisions of Nikolia. An example of a number registered in Carigrad would be
(6724) XXXX XXXX. A person calling a number registered in the same network group as the caller does not have to include dialing code of the area, however, while dialing numbers registered in another network group, a caller must type in its area dialing code.
Dialing numbers in Nikolia from abroad works by the principle of adding country calling code of Nikolia,
+645 in front of the number, then typing in the number in the same format as within Nikolia, area code - number.
Mobile service providers
Compared to landlines that have 4 digit calling code, mobile lines, however have 3. These are assigned to operators and are not assigned based on geographic area. Mobile phone users must type in full number including the calling code regardless if the receiver is user of the same mobile service provider, or is in the same area network group. There are 10 mobile network operators providing mobile communications in Nikolia, among which 4 are the most used by Nikolian citizens: Telekom Nikolije (dialing codes: 451, 452, 453, 454, 455 and 456), N-mobile (dialing codes: 457, 460, 461 and 462) and mobiNIK (dialing codes: 458, 459, 463 and 464)
Nikolia is, per administrative divisions, separated into two levels of network groups. First level is separation per voivodeship, and the second level is separation by county within the voivodeship network group.
