Dialing Formats and Procedures
When dialing a number within the same area code (3404), it is common to use the local 7-digit subscriber number without the area code. However, for calls from other regions within Argentina, the full national significant number must be dialed, which includes the national trunk prefix 0, the area code 3404, and the subscriber number. The format is: 0 3404 XXX XXXX.
For international callers, the Argentine country code +54 must be used, followed by the area code (without the leading zero) and the subscriber number. The international format is: +54 3404 XXX XXXX.
It is important to note that Argentina has implemented a closed dialing plan for geographic numbers, meaning that the area code must always be dialed for calls from outside the local area, even for calls within the same province. Overlay codes are not present in this region, so the area code remains unique for Las Colonias.
Caller Instructions
- Local calls (within the same area code): Dial the 7-digit subscriber number directly.
- National long-distance calls (from other Argentine cities): Dial 0 followed by 3404 and the subscriber number.
- International calls (from abroad): Dial the international access prefix (e.g., 00 from many countries), then 54, then 3404 and the subscriber number.
For example, to call a number in Esperanza from the United States, you would dial: 011 54 3404 XXX XXXX.
