In addition to the prefix number, of course you have also seen phone numbers that start with +62 instead of 0 ​​when making calls or registering an account online.

For those of you who don’t know, +62 is Indonesia’s own country code for international communication network connectivity set and defined by International Telecommunication Union (ITU) which is under the auspices of the UN organization (United Nations).

The ITU itself actually divides country codes for international communications network connectivity into 9 Zones, where Indonesia is included in Zone 6 for Oceania, Australia and others.

Several country codes within Zone 6 have codes that are almost consecutive, such as Malaysia with +60, Australia with +61, Indonesia with +62, Philippines with +63, Singapore with +65, Thailand with +66 and others.

The plus sign (+) in front of the numbers also plays an important role in indicating the country code because without this sign it is just an ordinary number. Using the +62 country code for Indonesia, it can be reached both abroad and domestically.

If you call using only 08xx instead of +628xx on the front of the number, the communication range will only be within Indonesia. So using +62 is very useful for international communication.
