Reference excerpt

The following are telephone codes in Cape Verde.

Overview Telephone numbers in Cape Verde are 7 digits long (except for special 1xx codes), and must always be dialed in their entirety (a closed dialing plan). The first 3 digits of a fixed-line (non-mobile) number correspond to its geographic area. Calls within a given 2xx area, and between certain areas, are considered local calls and priced accordingly. Mobile numbers have no geographic area, and calls to or from national mobile numbers are treated the same regardless of location.

History On July 3 2004, 2 was prepended to all fixed-line numbers, and 9 to all mobile numbers, increasing the number length to 7 digits.

Calling format xxx xxxx - calling inside Cape Verde +238 xxx xxxx - calling from outside Cape Verde The NSN length is seven digits.

Numbering plan

Number ranges In all cases listed, when a 2x range is split between two islands, one takes 2x0 through 2x4, while the other takes 2x5 through 2x9.

Special numbers 102 - Information 130 - Hospital 131 - Fire protection 132 - Police

Worked examples

Example 1 — a first encounter with Telephone numbers in Cape Verde

Start with the simplest possible case. Write down what Telephone numbers in Cape Verde 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 Cape Verde 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 Cape Verde 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 Cape Verde

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