Telephone numbers in Kazakhstan

Kazakhstan is a member of the International Telecommunication Union (ITU), and has been using the ITU-assigned country code 7 jointly with Russia in an integrated numbering plan since the breakup of the Soviet Union. In 2021, ITU reserved country code 997 for Kazakhstan, which the government planned to activate on 1 January 2023 with a two-year period of permissive dialling for the former code 7. in November 2023, when it was reported that Kazakhstan instead had been working on a new code-sharing agreement with Russia. ==Numbering plan==

Under an agreement with Russia signed on 11 June 2006, Kazakhstan was assigned zone codes 6xx and 7xx (x = 0 to 9) in the integrated numbering plan with ITU country code 7. 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 procedures==

Local and national dialling 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. International dialling 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. ==See also==
