Argentina at a glance
The numbers and facts you need before you dial.
What is the country code for Argentina?
Argentina answers to +54, slotted in right after your own exit code on any call into the country. On home soil, Argentines press the trunk 0 ahead of an area code. Then comes the famous wrinkle: to reach an Argentine mobile from abroad, you slip a 9 in behind the country code (+54 9) and leave off the domestic "15" that mobiles carry locally. Get that one digit right and everything else falls into line.
Code +54 was assigned to Argentina by the ITU under the E.164 plan. The “+” means “dial your local international exit code”; on a mobile, press and hold 0 to type it.
All four mean the same thing — they connect your call to Argentina.
How to call Argentina from anywhere
Landlines are the easy half: exit code, 54, the area code with its leading 0 dropped, then the number. Mobiles add the twist — exit code, 54, then a 9, then the area code, then the subscriber line, and never the domestic "15".
Full example: +54 11 XXX XXXX — drop the local leading 0 when calling from abroad.
Argentina phone number format explained
Argentina runs an open plan: area codes stretch 2–4 digits after the trunk 0, and the area code plus subscriber line always add up to 10 digits — the bigger the city, the shorter its code.
Landline
Pattern `0 [area code] [local number]`. Buenos Aires is 011; Córdoba 0351; small towns push to four-digit codes. At home: 011 1234 5678. From abroad: +54 11 1234 5678.
Mobile
At home it's `0 [area] 15 [number]`; from abroad that 15 disappears and a leading 9 takes its place, giving `+54 9 [area] [number]`. At home: 011 15 1234 5678. From abroad: +54 9 11 1234 5678.

Argentina mobile network prefixes
The prefix after +54 tells you which network issued the SIM — though number portability means it no longer guarantees the operator.
Claro (América Móvil)
the largest by share; nationwide mobile coverage across every area code.
Movistar (Telefónica)
a major operator with countrywide 4G/5G.
Personal (Telecom Argentina)
a major operator with nationwide reach.
Argentina time zone
Argentina runs on Argentina Time (ART), UTC-3, all year — it does not observe daylight saving time, so the offset never changes.
** Sitting just 1–2 hours ahead of US Eastern, Argentina shares almost the whole American working day — a rare luxury for the Americas. To catch Europe, ring during Buenos Aires' morning, which is their afternoon. With no clock-changes on Argentina's side, the only thing that ever shifts the gap is the US switching its own DST.

Common mistakes when calling Argentina
Almost every failed international call is a formatting issue, not a network issue.
**Dropping the mobile "9":** This is the one that catches everyone. From abroad an Argentine mobile must read **+54 9** before the area code
leave the 9 off and the call dies or rings a landline instead.
**Carrying the domestic "15" overseas:** That 15 is for in-country dialing only. From abroad it becomes the leading 9
use one or the other, never both in the same number.
**Holding the leading 0:** Let it go on calls from abroad
it's +54 **11**…, not +54 **011**…
**Reading the carrier off the number:** Portability plus shared geographic codes means a number reveals nothing about Claro, Movistar or Personal
**Reading the carrier off the number:** Portability plus shared geographic codes means a number reveals nothing about Claro, Movistar or Personal.
**Misjudging the code length:** Codes run 2–4 digits, but area code and subscriber line always total 10
get the split wrong and the call won't connect.
Tips to reduce the cost of calling Argentina
Send calls over IP
MCM carries Argentina traffic across the internet, well under roaming or IDD pricing.
Pick landlines for the long calls
fixed-line termination usually beats mobile, and it sidesteps the 9/15 mobile dance entirely.
Use the tiny time gap
being near-aligned with US hours means fewer missed-call callbacks and less wasted spend.
**Keep a local Argentina DID** so customers in Buenos Aires or Córdoba reach you at a domestic rate.

Argentina +54 — FAQ
Why does my call to an Argentine mobile keep failing?expand_more
You're almost certainly missing the 9. From abroad a mobile reads +54 9 + area code + number — no 9, no connection.
Where exactly does the 9 go?expand_more
Right after the country code and before the area code: +54 **9** 11 1234 5678 for a Buenos Aires mobile.
What is the "15" my Argentine contact mentions?expand_more
It's the domestic mobile prefix locals dial inside the country. Calling from abroad you drop the 15 and use the leading 9 instead — never both.
How do I reach an Argentine landline from the US?expand_more
Dial 011 + 54 + area code (leading 0 removed) + number — no 9 for landlines.
What's Buenos Aires' area code?expand_more
11 — dialed 011 at home, +54 11 from abroad (landline) or +54 9 11 (mobile).
Can I tell whether a number is Claro, Movistar or Personal?expand_more
No — portability and shared geographic codes mean the digits give nothing away.
Does Argentina change its clocks?expand_more
No — it stays on ART (UTC-3) all year, so the offset only moves when other countries shift their own DST.
Can MCM handle the 9/15 routing for my business number?expand_more
Yes — MCM provisions Argentine DIDs and manages the mobile dialing rules so your team never has to.
