Country codes are defined by the International Telecommunication Union (ITU) in ITU-T standards E.123 and E.164. The prefixes enable international direct dialing (IDD). Country codes constitute the international telephone numbering plan. They are used only when dialing a telephone number in a country or world region other than the caller's.
The differences between the prefixes are the length of the number (six or ten digits), the license cost to use them each year (approximately A$1 for 1800 and 1300, A$10,000 for 13 numbers) and the call cost model. 1300 numbers [8] and 13 numbers share call costs between the caller and call recipient, whereas the 1800 model offers a national ...

The IUPAC nomenclature of organic chemistry, for example, uses the numerical prefixes derived from Greek, except for the prefix for 9 (as mentioned) and the prefixes from 1 to 4 (meth-, eth-, prop-, and but-), which are not derived from words for numbers. These prefixes were invented by the IUPAC, deriving them from the pre-existing names for ...

The Type Allocation Code identifies a particular model (and often revision) of wireless telephone for use on a GSM , UMTS , LTE , 5G NR , iDEN , Iridium or other IMEI-employing wireless ...
As a matter of fact, each area code has only a limited number of prefixes assigned, and these are locally limited within the area. For example, the (0342) area has numbers with a 456- prefix, mostly located in the centre of Santa Fe. It also has numbers with a 460- prefix, usually for phone lines in the north east of the city.
