Number structure

Following the

break-up of the Soviet Union The dissolution of the Soviet Union, also negatively connoted as rus, Разва́л Сове́тского Сою́за, r=Razvál Sovétskogo Soyúza, ''Ruining of the Soviet Union''. was the process of internal disintegration within the Sov ...

, Russia and Kazakhstan retained the same +7 country code for inbound calling. Under an agreement with Russia signed on 11 June 2006, Kazakhstan is assigned zone codes 6xx and 7xx (x = 0 to 9) under the unified plan. Hence, all numbers in Kazakhstan start with (+7) 6xx or (+7) 7xx.

Geographical numbers

Geographical (landline) telephone numbers in Kazakhstan consist of ten digits: *zone code: the leading three digits *area code: the following one or two digits *subscriber number: the last six or five digits, depending on the length of the area code. Geographic numbers use zone codes in the range from 710 to 729. Prior to the 2006 agreement, landlines used zone codes in the 3xx range; as zone codes 3xx were assigned to Russia, zone codes in Kazakhstan were changed by substituting the leading '3' with '7' in mid-2007.

Non-geographical numbers

Non-geographical numbers start with 75x or 76x.

Mobile numbers

Mobile numbers have 10 digits starting with 70x or 77x.

Dialling pattern

Local and national dialling

Calls within a single area code can be made by dialling the 7-digit subscriber number alone. For long-distance calls, callers from landline numbers dial the long distance prefix 8, wait for a tone, and then dial the zone code and number. Modern exchanges no longer require waiting for the tone, nor does mobile telephony where the long-distance prefix is not required.

International dialling

The international dialling prefix is 8~10 – callers dial 8, wait for a tone, and then dial 10 immediately followed by the
