A toll-free telephone number or freephone number is a telephone number that is billed for all arriving calls. For the calling party, a call to a toll-free number from a landline is free of charge. A toll-free number is identified by a dialing prefix similar to an area code. The specific service access varies by country.

Telephone numbers in Cyprus follow a closed telephone numbering plan which was adopted on 1 December 2001. As a result, for landline phone numbers the digit 2 followed by the old area code was affixed to the subscriber number and for mobile phones 9 was affixed to the phone number. The plan is also used in Akrotiri and Dhekelia.
PhONEday was a change to telephone numbering in the United Kingdom on Sunday 16 April 1995. A shortage of unique telephone numbers in the old dialling system meant that it was becoming increasingly difficult in certain areas of the country to assign unique numbers to new subscribers. To counteract this, dialling codes starting with 0 were changed to start with 01. In Bristol, Leeds, Leicester, Nottingham and Sheffield, the existing area codes, which were 5 digits in length, were instead entirely replaced with new codes comprising 4 digits, to increase the amount of possible numbers by a factor of ten. The changes made possible the ability to provision new numbers in each of these five cities. It also had the effect of assigning all geographic landline telephone numbers into one range of numbers starting with 01, allowing for further changes to be made at the Big Number Change in 2000. A £16m advertising campaign, and an eight-month parallel period during which both old and new codes were active, preceded the change. PhONEday followed a change made in May 1990, when the old London area code 01 was released from use, permitting all United Kingdom geographic numbers to begin with this prefix. Originally planned in 1991 to take place in 1994, in 1992 the change was postponed until the Easter Sunday bank holiday in 1995.
Lithuania uses an open telephone numbering plan with all phone numbers having nine digits, including the prefix "8", a 1–3 digit area code, and a 5–7 digit subscriber telephone number.

This is a discussion of telephone numbers in Ukraine. The nation of Ukraine has country code +380. It switched to the European Union's common dialing plan in 2009. Thus, Ukrainian phone numbers consist of a 2-digit zone code, an optional subzone code, an optional filler, and the local phone number. However, following the 2022 Russian invasion of Ukraine, the regions of Crimea, Donetsk, and Luhansk were given Russian telephone codes instead, as if they were following telephone numbers in Russia.

Telephone numbers in Russia are administered by Roskomnadzor, and Ministry of Digital Development, Communications and Mass Communications of the Russian Federation. Russia's National Numbering Plan (NNP) is a four-level telephone numbering plan with local, zone, country, and international scopes, implementing a closed numbering plan, in which the number of digits of all national significant numbers (NSN) assigned to subscriber telephones is fixed at ten, with three digits for the area code, and a seven-digit subscriber number which includes a zone code of up to two digits. Internationally, Russia participates in the numbering plans of the International Telecommunication Union (ITU) provided by recommendations E.164 and E.123, using the telephone country code 7.
+7 is an ITU country code for telephone numbering. It was originally assigned to the Soviet Union. After the 1991 dissolution of the Soviet Union, the code continued to be used by the fifteen successor states, the majority of whom switched to own country codes from the +3xx and +9xx ranges between 1993 and 1998.

All telephone numbers in Panama are seven or eight digits long and there are no area codes. All numbers that both begin with 6 and have 8 digits are mobile numbers. All landline numbers have 7 digits. The first digit of landline numbers may be used to vaguely identify the location of the caller. Mobile phones were also assigned 7 digit numbers until 2005, when they were moved to their own number space with 8 digits. Mobile numbers are recycled if the user is marked as inactive by the mobile service provider, and landline numbers are also recycled if a user cancels their landline phone service.
