Area Code 477 – Artigas

Overview of Area Code 477 (Artigas, Uruguay)

Area code 477 is a geographic National Destination Code (NDC) assigned to the Artigas Department in the northwestern region of Uruguay, bordering Brazil. It serves the departmental capital, Artigas, and its surrounding localities, including Bella Unión, Tomás Gomensoro, and Baltasar Brum. The code is part of the Uruguayan public switched telephone network (PSTN) and is used for fixed-line services, including traditional copper lines, fiber-to-the-home (FTTH), and fixed wireless access (FWA) offerings from national operators such as Antel and regional licensed carriers.

Geographic Coverage and Administrative Jurisdiction

The 477 code covers the entire Artigas Department, which is one of Uruguay's 19 administrative divisions. The department is known for its agricultural and livestock production, and its proximity to the Brazilian state of Rio Grande do Sul. The largest population centers within the code include the city of Artigas (the departmental seat) and Bella Unión, located at the confluence of the Uruguay and Cuareim rivers. Because the department is sparsely populated compared to Montevideo, the 477 code serves a relatively low subscriber density, but it remains essential for local businesses, government offices, and residential connectivity.

Dialing Formats and Caller Instructions

For callers within Uruguay, the national trunk prefix 0 is used before the area code. To call a fixed line in Artigas from another department, dial 0 477 XXX XXX (where X represents the subscriber number). For example, a local number might be formatted as 0 477 123 456. When calling from abroad, the international access code (e.g., 00 from most countries) is followed by Uruguay's country code +598, then the area code without the leading zero: +598 477 XXX XXX. For instance, a caller from the United States would dial 011 598 477 123 456, while a caller from the United Kingdom would dial 00 598 477 123 456.

Local calls within the same area code do not require the trunk prefix or area code; subscribers can dial the seven-digit local number directly. However, due to the small size of the local exchange, most users are accustomed to full national dialing for clarity.

Overlay and Numbering Plan Considerations

As of the latest ITU-T E.164 national numbering plan updates, Uruguay has not implemented overlay codes for Artigas; the 477 code remains exclusive to the department. The subscriber number length is seven digits, making the total national significant number (NSN) length eight digits (including the area code). The country code +598 is used for all international calls. No major numbering changes are anticipated in the near term, but users should verify with their service provider for any future migration to IP-based telephony or number portability adjustments.

Practical Guidance for Local and Foreign Callers

For local callers, always include the area code when calling from a mobile phone, as mobile numbers in Uruguay are non-geographic and begin with 9x. For foreign callers, ensure you have the correct international exit code and that you omit the leading '0' of the national trunk prefix. If you are unsure about a number's validity, you can consult the official Uruguayan communications regulator (URSEC) or your telecom operator for assistance.
