Area Code 3758 – Apóstoles, Misiones

Overview of Area Code 3758

Area code 3758 is a geographic National Destination Code (NDC) assigned to the city of Apóstoles and its surrounding administrative district in the province of Misiones, Argentina. This code is part of the national numbering plan under the country calling code +54, as defined by ITU-T E.164. The region is located in the northeastern part of Argentina, near the border with Brazil, and is known for its agricultural production and yerba mate plantations.

Geographic Coverage and Jurisdiction

The 3758 area code covers the urban area of Apóstoles, which serves as the head town of the Apóstoles Department. It also includes smaller localities and rural areas within the department, such as San José and Azara. Administratively, these areas fall under the jurisdiction of the Province of Misiones. The code is used for fixed-line (PSTN) services, and as with other geographic codes in Argentina, it is assigned to the local incumbent operator, typically Telecom Argentina, though other licensed providers may offer services in the region.

Dialing Formats

For local callers within Argentina, dialing a number in the 3758 area code requires the use of the national trunk prefix 0 followed by the area code and the subscriber number. The subscriber number for this area code is typically 7 digits long. Therefore, a national call would be placed as: 0 3758 1234567.

For international callers, the format is: +54 3758 1234567. When calling from abroad, the leading '0' is omitted, and the '+' sign represents the international access code, which varies by country (e.g., 011 from the US, 00 from most European countries).

It is important to note that Argentina's numbering plan does not use area code overlays; each geographic area has a single NDC. However, due to number portability, a fixed-line number may be ported to another operator, but the geographic area code remains unchanged, preserving the association with the original location.

Caller Instructions

Local callers (within the same area code) can often dial just the 7-digit subscriber number without the area code, depending on the local dialing rules. However, for clarity and to avoid misdialing, it is recommended to always use the full national format, especially when calling from mobile phones.

Foreign callers must replace the international access code with the '+' sign when using a mobile phone, or use the appropriate exit code for landlines. Ensure that you drop the leading '0' of the national trunk prefix.
