Telephone numbers in Kazakhstan are regulated under the auspices of the Telecommunications Committee of the Ministry of Digital Development, Innovations, and Aerospace Industry in the Republic of Kazakhstan.[1] They are administered by telecommunication providers, notably Kazakhtelecom, a state-backed and the largest national operator.

Kazakhstan has been sharing the country code 7 with Russia since its independence in 1991. In 2021, the country was assigned the code 997[2] which was to be activated in January 2023. In early 2023, however, the country applied for a change of code to 77.[3]


Following the break-up of the Soviet Union, Russia and Kazakhstan retained the same country code 7 for inbound calling. Under an agreement with Russia signed on 11 June 2006, Kazakhstan was assigned zone codes 6xx and 7xx (x = 0 to 9) under the unified plan.

Geographical numbers[edit]

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.[4] 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[edit]

Non-geographical numbers start with 75x or 76x.[4]

Mobile numbers[edit]

Mobile numbers have 10 digits starting with 70x or 77x.[4]

Dialling procedures[edit]

Local and national dialling[edit]

Calls within a single area code can be made by dialling the seven-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.[citation needed]

International dialling[edit]

The international dialling prefix is 8~10 – callers dial 8, wait for a tone, and then dial 10 immediately followed by the country code and the remainder of the number. Modern exchanges no longer require waiting for the tone.

Country code[edit]

Kazakhstan is a member of the International Telecommunication Union (ITU), and has been using an ITU-assigned country code 7 jointly with Russia since the breakup of the Soviet Union. In 2021, Kazakhstan was assigned country code 997 which it planned to activate on 1 January 2023 with a two-year period of permissive dialling using the former code 7.[2]

In 2022, however, Kazakhstan has filed another application to ITU, this time for the assignment of the country code 77.[3] In December 2022, and then again in March 2023, an ITU expert group recommended against this proposal, pointing to the unavailability of the 77 code for assignments as well as the ITU policy of assigning only three-digit country codes.[5][6]
