Telephone numbers in Cyprus

Telephone numbers in Cyprus is a mathematics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Telephone numbers in Cyprus rather than just read about it. In short: 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.

Key takeaways

Telephone numbers in Cyprus belongs to mathematics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Telephone numbers in Cyprus to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Telephone numbers in Cyprus from memory before moving on to harder problems.

Reference excerpt

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.

Currently Under the new system, these changed to numbers with eight digits, to be dialled from within Cyprus or abroad.

Landline number in Nicosia called from within Cyprus (including Nicosia): 22 xxxxxx Landline number in Nicosia called from abroad: +357 22 xxxxxx Mobile phone number called from within Cyprus: 9x xxxxxx (during that period only 09 code was in use, from CYTA) Mobile phone number called from abroad: +357 9x xxxxxx As with fixed line numbers, under the new system, these changed to numbers with eight digits, to be dialled from within Cyprus or abroad. Numbering portability between the networks is possible.

Mobile phone number called from within Cyprus: 9x xxxxxx (the first x depends on the company, as seen below, the second x is random except when it follows a 4 for Epic)

All numbers (except short codes) in Cyprus now have eight digits, hence the new numbering plan's promotional logo (in advertising) was an octopus called TESA (from Greek Τελικό Εθνικό Σχέδιο Αριθμοδότησης Final National Numbering Plan).

In the past Previously, landline numbers consisted of the trunk code 0, the area code, and a six-digit number.

Landline number in Nicosia called from Nicosia: xxxxxx Landline number in Nicosia called from inside Cyprus (other than Nicosia): 02 xxxxxx Landline number in Nicosia called from abroad: +357 2 xxxxxx Mobile phone numbers had the prefix 09, followed by six digits, which had to be dialled in full.

Mobile phone number called from within Cyprus: 99 xxxxxx (during that period only 09 code was in use, from CYTA) Mobile phone number called from abroad: +357 9 xxxxxx As with fixed line numbers, under the new system, these changed to numbers with eight digits, to be dialled from within Cyprus or abroad. Numbering portability between the networks is possible.

Mobile phone number called from within Cyprus: 9xxxxxxx (where the first x is either 9 or 7 which belongs to CYTA, 6 which belongs to Epic, 5 to PrimeTel 4 to Cablenet) Mobile phone number called from abroad after 12/2001: +357 9x xxxxxx

Regional codes The 5 districts of Cyprus under government control each have their own 2 digit dialling code for landline numbers. These are:

(Note: Kyrenia District is fully within the area not under government control. Although some websites claim the code 27 to be for Kyrenia, no phone number is assigned to it.) After the district code, a 3 digit "area code" is written, which different for every town (Most towns have multiple codes, depending on how many numbers are in it). For example the prefixes 723 and 724 are used for Xylotymbou There isn't a list that displays all the codes, and from researching the yellow pages, the codes don't seem to be able to be narrowed down further and are mostly random.

Situation in Northern Cyprus

In Northern Cyprus, the Turkish numbering plan is used. The Turkish area code 0392 has been assigned for use with landline numbers, with 0533 Kuzey Kibris Turkcell and 0542 KKTC Telsim being used for mobile phones, while the Turkish country code +90 is used for calls from the rest of the world. For calls from the Republic of Cyprus to Northern Cyprus, the code 0139 followed by the 7-digit subscriber number is used, which are charged at local call rates. 0139 is still used for direct calls to Northern Cyprus even after the numbering plan change of December 2001. For calls from Northern Cyprus to the Republic of Cyprus, area code 0123 is used but the call is charged at international rates. It is also possible to use the international prefix 00357. These direct telephone connections between the two halves of the island are operated by the United Nations exchange, which allows direct telephone calls between the two communities is in place since 4 May 1998. After 2 March 2003, direct international calls from the Republic of Cyprus to Turkey are possible. Now callers from the Republic of Cyprus can call Northern Cyprus either through Turkey dialing 0090 392 xxxxxxx (calls charged at international rates), or using 0139 (calls charged at local rates).

Worked examples

Example 1 — a first encounter with Telephone numbers in Cyprus

Start with the simplest possible case. Write down what Telephone numbers in Cyprus claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Telephone numbers in Cyprus before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Telephone numbers in Cyprus ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Telephone numbers in Cyprus

In research: Telephone numbers in Cyprus appears in mathematics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Telephone numbers in Cyprus in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Telephone numbers in Cyprus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cyprus communications-related lists, Telecommunications in Cyprus, Telephone numbers by country, so understanding it makes those chapters shorter.
In everyday life: Look for Telephone numbers in Cyprus outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
