ISO 3166-2:ES

ISO 3166-2:ES is a science 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 ISO 3166-2:ES rather than just read about it. In short: ISO 3166-2:ES is the entry for Spain in ISO 3166-2, part of the ISO 3166 standard published by the International Organization for Standardization (ISO), which defines codes for the names of the principal subdivisions (e.g., provinces or states) of all countries coded in ISO 3166-1. Currently for Spain, ISO 3166-2 codes are defined for two levels of subdivisions: 17 autonomous communities and two autonomous cities in…

Key takeaways

ISO 3166-2:ES belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect ISO 3166-2:ES to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of ISO 3166-2:ES from memory before moving on to harder problems.

Reference excerpt

ISO 3166-2:ES is the entry for Spain in ISO 3166-2, part of the ISO 3166 standard published by the International Organization for Standardization (ISO), which defines codes for the names of the principal subdivisions (e.g., provinces or states) of all countries coded in ISO 3166-1. Currently for Spain, ISO 3166-2 codes are defined for two levels of subdivisions:

17 autonomous communities and two autonomous cities in North Africa 50 provinces Each code consists of two parts, separated by a hyphen. The first part is ES, the ISO 3166-1 alpha-2 code of Spain. The second part is one or two letters. For the provinces, the letters were originally used in vehicle registration plates. The codes for the following provinces are based on the names of their capital cities rather than their own names:

Álava/Araba (ES-VI): Vitoria Asturias (ES-O): Oviedo Illes Balears (ES-PM): Palma Cantabria (ES-S): Santander Gipuzkoa (ES-SS): San Sebastián La Rioja (ES-LO): Logroño Las Palmas (ES-GC): Las Palmas de Gran Canaria Bizkaia (ES-BI): Bilbao

Current codes Subdivision names are listed as in the ISO 3166-2 standard published by the ISO 3166 Maintenance Agency (ISO 3166/MA). ISO 639-1 codes are used to represent subdivision names in the following administrative languages:

(es): Spanish (eu): Basque (ca): Catalan (gl): Galician Except where noted, the names given are in Spanish (Castilian). In autonomous communities and provinces where any of the regional languages is the sole official language of toponymy, the Spanish name is given in square brackets for information. In subdivisions where both a regional language and Spanish are co-official languages of toponymy, both names are listed vertically.

Autonomous communities; autonomous cities in Spain

Notes

Provinces

Changes The following changes to the entry have been announced in newsletters by the ISO 3166/MA since the first publication of ISO 3166-2 in 1998:

Special territories The following two areas not covered by European Union Customs arrangements are also exceptionally reserved ISO 3166-1 alpha-2 codes on the request of the World Customs Organization:

EA Ceuta, Melilla IC Canary Islands However, these codes do not correspond in any way to the ISO 3166-2 codes of the territories.

Worked examples

Example 1 — a first encounter with ISO 3166-2:ES

Start with the simplest possible case. Write down what ISO 3166-2:ES claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 ISO 3166-2:ES 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 ISO 3166-2:ES 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 ISO 3166-2:ES

In research: ISO 3166-2:ES appears in science 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 ISO 3166-2:ES 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: ISO 3166-2:ES is common in secondary-school and first-year university syllabi. It links to neighbouring topics Autonomous communities of Spain, ISO 3166, Provinces of Spain, so understanding it makes those chapters shorter.
In everyday life: Look for ISO 3166-2:ES 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.
