Area Code 79 – Sergipe

Overview of Area Code 79 (Sergipe, Brazil)

Area code 79 is the National Destination Code (NDC) assigned to the state of Sergipe, located in the Northeast Region of Brazil. It is a geographic area code, meaning it is tied to a specific territory and is used for both fixed-line (PSTN) and mobile services within that state. The code is administered under Brazil's national numbering plan, which follows the ITU-T E.164 recommendation. Sergipe is the smallest state in Brazil by area, but its capital, Aracaju, is a major urban center and the primary city served by this code.

Geographic Coverage and Major Cities

Area code 79 covers the entire state of Sergipe, including its capital Aracaju and other significant municipalities such as Nossa Senhora do Socorro, Lagarto, Itabaiana, São Cristóvão, and Estância. The code is used for all local fixed-line and mobile numbers within the state, ensuring that calls to any subscriber in Sergipe are routed correctly.

Dialing Formats and Procedures

Understanding the correct dialing format is crucial for both domestic and international callers.

• Local Calls (within Sergipe): When dialing a number within the same area code, you typically dial only the 8-digit subscriber number (for fixed lines) or the 9-digit mobile number (including the leading '9'). For example, to call a fixed line in Aracaju, you would dial: XXXX-XXXX. For a mobile, you would dial: 9XXXX-XXXX.
• Domestic Long-Distance (from other Brazilian states): When calling from outside Sergipe, you must dial the Brazilian trunk prefix 0, followed by the carrier selection code (e.g., 15, 21, 31), then the area code 79, and finally the subscriber number. For example, to call a fixed line in Aracaju from São Paulo, you would dial: 0 15 79 XXXX-XXXX. For a mobile, you would dial: 0 15 79 9XXXX-XXXX.
• International Calls (from outside Brazil): To call a number in Sergipe from abroad, you need to dial your country's international access code (e.g., 011 from the US, 00 from most European countries), followed by Brazil's country code 55, then the area code 79, and the subscriber number. For example, from the US, you would dial: 011 55 79 XXXX-XXXX (fixed) or 011 55 79 9XXXX-XXXX (mobile).

Overlay and Numbering Considerations

Currently, there is no overlay code for Sergipe; area code 79 remains the sole NDC for the state. However, due to the increasing demand for telecommunication services, Brazil's National Telecommunications Agency (ANATEL) has implemented measures to expand numbering capacity, such as adding the digit '9' to all mobile numbers (completed in 2016). This change ensures that mobile numbers are always 9 digits long, starting with '9', allowing for a larger pool of available numbers.

Practical Tips for Callers

When calling Sergipe, always verify the number length: fixed lines have 8 digits, while mobile numbers have 9 digits (starting with 9). For international callers, remember to drop any leading '0' from the area code when dialing from abroad. For local callers, using the carrier selection code is mandatory for long-distance calls, but you can choose any carrier; the cost may vary. For VoIP users, ensure your service provider supports calls to Brazilian geographic numbers and be aware of any additional charges.
