Reference excerpt

Telephone country code: 506 International Call Prefix: 00 As of 2010 the government body in charge of allocations is the Superintendencia de Telecomunicaciones SUTEL.

History of allocations Prefix 00 was reserved for international calls, while prefix 9 was assigned to special numbers, such as 911. Toll-free numbers start with 800 followed by 7 digits while premium-rate numbers start with 900 followed by 7 digits. Before 1994, all phone numbers in Costa Rica were six digits long. The Instituto Costarricense de Electricidad, which at that time had the monopoly on telecommunications, introduced a system in which the telephone numbers in every province were assigned a prefix to make them 7 digits long. This numbering system was effective for some time. However, the boom of mobile phone customers since the introduction of GSM around 2000 and the expansion of metropolitan areas caused a serious shortage of available numbers. Thus many GSM-based customers used numbers starting with 3 and many residents of San Jose province had telephone numbers starting with prefixes other than 2. Since March 20, 2008, a renewed numbering system added the prefix 2 for all landlines and 8 for all mobile phone numbers. This system was implemented in order to face the introduction of 1.5 million 3G W-CDMA customers in Q1 2009. The transition to 8-digit numbers was heavily publicized in Costa Rican media. However, the change caused considerable confusion among foreigners. Also, all calls dialed using the old 7-digit version of the phone number are automatically redirected to a voice message with information about the change. In 2010, after the end of the government monopoly in telecommunications, prefixes 3, 4, 5, 6 and 7 were assigned to private operators. 8-digit numbers are commonly written one of two ways: "xxxxxxxx" or "xxxx-xxxx"

Worked examples

Example 1 — a first encounter with Telephone numbers in Costa Rica

Start with the simplest possible case. Write down what Telephone numbers in Costa Rica 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 Costa Rica 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 Costa Rica 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 Costa Rica

In research: Telephone numbers in Costa Rica 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 Costa Rica 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 Costa Rica is common in secondary-school and first-year university syllabi. It links to neighbouring topics Costa Rica communications-related lists, Telecommunications in Costa Rica, Telephone numbers by country, so understanding it makes those chapters shorter.
In everyday life: Look for Telephone numbers in Costa Rica 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.
