The primary international country code designated for [Antarctica](
https://www.google.com/search?kgmid=/m/0jfx) is +672. However, because the continent is governed by the [Antarctic Treaty System](
https://www.ats.aq/) and has no single government, bases run by different nations use distinct dialing setups. [1, 2, 3]
Here are the specific international codes and dialing formats used to reach various research stations:
## The Global Antarctic Code (+672)
This code is primarily used by the [Australian Antarctic Division](
https://www.antarctica.gov.au/) to route calls directly to their active bases. To dial them, you enter +672, followed by the specific Station Area Code, and then the person's 4-digit extension: [2, 4]
| Base / Location | Country Code | Station Area Code | Full Dialing Prefix |
|
-|-|
-|-|
| Davis Base[](
https://www.google.com/search?kgmid=/m/01c4m0) | +672 | 10 | +672 10 xxxx |
| Mawson Base[](
https://www.google.com/search?kgmid=/m/01c4md) | +672 | 11 | +672 11 xxxx |
| Casey Base[](
https://www.google.com/search?kgmid=/m/01c4l6) | +672 | 12 | +672 12 xxxx |
| Macquarie Base | +672 | 13 | +672 13 xxxx |
## National Country Codes Used in Antarctica
Many nations route phone systems for their bases through their home country's standard international calling infrastructure rather than the +672 code. [5, 6]
*
* +54 (Argentina): Reaches Argentinian bases like Esperanza Base or Marambio Base.
* +56 (Chile): Reaches Chilean outposts like [Eduardo Frei Montalva Station](
https://www.google.com/search?kgmid=/m/0c9_72) or González Videla Station.
* +44 (United Kingdom): Reaches British bases like [Rothera Research Station](
https://www.google.com/search?kgmid=/g/11bwdqp0qh) or [Halley Research Station](
https://www.google.com/search?kgmid=/m/01ylfn).
* +39 (Italy) / +33 (France): Reaches the jointly operated [Concordia Station](
https://www.google.com/search?kgmid=/m/047b17).
* +1 (United States / Canada): Reaches U.S. stations like McMurdo Station or Amundsen-Scott South Pole Station via dedicated satellite tie-lines that link directly back to the U.S. domestic network. [5]

If you are trying to dial a specific person, let me know:
*
* What specific base or country are you trying to call?
* Do you already have their 4-digit local extension?
*
I can give you the exact step-by-step dialing sequence from your location.
