ISO country codes are internationally recognized codes that designate every country a two-letter or three-letter combination. These codes are often used as abbreviations in statistical analyses, tables, figures, or maps. They are also used for top-level domains for countries on the internet. For example, the two-letter country code for Austria is 'AT'. This is in contrast to Australia, which has a three-letter code, 'AUS', and is only used during events with international participants.

The two-letter abbreviation for Austria is 'AT'
The two-letter abbreviation for Austria is AT. This is in keeping with the ISO 3166 classification system, which defines unique two- and three-letter codes for countries worldwide. These ISO country codes are internationally recognized and are used to designate every country and most dependent areas.
The two-letter country codes are always written in capital letters and are often used as abbreviations in statistical analyses, tables, figures, or maps. For example, the two-letter codes are used as suffixes for top-level domains for countries on the internet, such as .us for the United States, .fr for France, or .de for Germany.
The three-letter country codes are also commonly used, especially at events with international participants, such as sports meetings or song contests. For instance, CAN for Canada, DNK for Denmark, and AUS for Australia.
It is important to note that the protocol order in which countries are listed in tables, figures, or maps is based on the alphabetical list of country names in their national language for EU and EFTA Member States and candidate countries. For potential candidates, the order is based on the alphabetical order of their country codes.

ISO 3166-1 alpha-2 is the name of the two-letter country code system
These codes are used in web domain names and top-level domains (ccTLDs), such as '.fr' for France or '.de' for Germany. The Internet Assigned Numbers Authority (IANA) assigns these ccTLDs, usually following the alpha-2 codes. However, there are exceptions, such as the United Kingdom, which uses '.uk' instead of '.gb'.
The ISO 3166-1 alpha-2 codes are also used in software localisation, paired with language codes from the ISO 639-1 standard to create locale identifiers. These identifiers are crucial for addressing cultural nuances and local conventions. The codes are also used in automotive labelling and by the United Nations for international vehicle registration codes.
In the case of Austria, its two-letter country code is 'AT'. This code is used in various contexts, including internet domains, software localisation, and international standardisation. The ISO 3166-1 alpha-2 code system provides a standardised way to represent countries and territories using just two letters, making it a concise and widely adopted system.

Country codes are used in top-level domains for countries on the internet
Country codes are an internationally recognised system that assigns a combination of two or three letters to every country and most dependent areas. These codes are used to indicate a site's relation to a specific country or region and are referred to as country code top-level domains (ccTLDs). The two-letter country code suffixes are used in top-level domains for countries on the internet. For example, '.at' is the country code top-level domain for Austria.
The first ccTLD was registered in 1985, and it was .us for the United States. Other early ccTLDs included .uk for the United Kingdom, .il for Israel, .au for Australia, and .de for Germany, all of which were registered in 1985 and 1986. As of 20 May 2017, there were 255 country-code top-level domains using two-character codes in the Latin alphabet.
ICANN (Internet Corporation for Assigned Names and Numbers) is the company that regulates the allocation of all ccTLDs. An NIC (Network Information Center) or Domain Name Registry is responsible for the management and registration of all regional domain extensions in a country. Country-specific domain extensions generally indicate the region or language that the website’s content is relevant for.
The guidelines for ccTLDs are determined by their respective countries. For example, the American (us), Japanese (jp), Canadian (ca), French (fr), and German (de) domains have a local-presence requirement, meaning that only those with a connection to the ccTLD can register subdomains. Other ccTLDs, like .com or .org, are generic top-level domains that refer to specific themes rather than regions and can include more than two letters.
In addition to the standard ccTLD, some countries have variations in other languages. For example, Sri Lanka uses .lk as its country code but also has TLDs in Sinhalese and Tamil: .ලංකා and .இலங்கை, respectively. These internationalised domain names can use characters from the Latin alphabet with accents, as well as characters from other alphabets.

Country codes are internationally recognised and are always written in capital letters
Country codes are internationally recognised codes that designate every country and most dependent areas. These codes are a two-letter combination, always written in capital letters, like an acronym that stands for a country or state. For example, the two-letter suffixes .us (United States), .fr (France), and .de (Germany) are used for top-level domains for countries on the internet.
The ISO 3166 classification system defines unique two- and three-digit codes for all countries worldwide. The ISO country codes are used throughout the IT industry by computer systems and software to ease the identification of country names. They are also used in statistical analyses, tables, figures, or maps, where the country code is often used as an abbreviation.
The two-letter country codes are always written in capital letters. For instance, the code for Canada is 'CA', for Denmark is 'DK', and for Australia is 'AU'. These three-letter codes are also often used at events with international participants from various countries, such as sports meetings or song contests.
The ISO 3166-1 alpha-2 system ensures that each country has a unique two-letter code. This is different from the ISO 639-1 system, which uses a different set of two-letter codes for languages. When a country code is deleted, an entry for the corresponding former country name is included in ISO 3166-3, and it is assigned a four-letter code, with the first two letters being the old alpha-2 code.

There is a different set of two-letter codes used for languages
The two-letter abbreviation for Austria is 'AT'.
There is indeed a different set of two-letter codes used for languages. ISO language codes are standardized codes that represent languages and language families. They are defined by the International Organization for Standardization (ISO) and are used internationally to identify languages in various contexts. ISO 639-1 is the first part of the ISO 639 standard, which defines two-letter codes for a wide range of languages. These codes are often used in contexts where brevity is important, such as in URLs, domain names, and language tags. For example, "en" stands for English, "fr" for French, and "es" for Spanish.
ISO 639-2 is used when more granularity is needed in language classification. It provides both two-letter and three-letter codes, accommodating a larger set of languages and variations. ISO 639-2 codes are commonly used in libraries, archives, and other academic or cultural contexts. For example, "yue" for Cantonese and "hak" for Hakka.
ISO 639-3 is an extension of the ISO 639 standard and aims to cover the full range of known languages worldwide. It provides codes for individual languages and distinct dialects, such as "zh-CN" for Simplified Chinese and "zh-TW" for Traditional Chinese. These codes are used for linguistic research, documentation, and preservation efforts.
The ISO 639 Maintenance Agency is responsible for maintaining and updating the standard, and the codes often reflect the English or native name of the language. ISO language codes provide a consistent and standardized way to represent languages, enabling accurate language identification, data organization, and multilingual support.
