Area Code 4364 – Trinidad/Flores

Overview of Uruguay Area Code 4364

Area code 4364 is a geographic National Destination Code (NDC) assigned to the city of Trinidad, the capital of the Flores Department in central Uruguay. This code is part of the national numbering plan administered by the Uruguayan communications regulator (URSEC) and is used for fixed-line (PSTN) services within this specific locality.

Geographic Coverage and Administrative Jurisdiction

The 4364 code covers the urban and suburban areas of Trinidad, as well as nearby rural communities within the Flores department. Trinidad serves as the administrative, commercial, and cultural hub of the region, with a population of approximately 21,000 inhabitants. The area is known for its agricultural production, particularly dairy and grain farming, and its historical significance as the birthplace of the Uruguayan national hero, José Gervasio Artigas.

Dialing Formats and Caller Instructions

• Local calls (within Trinidad): When dialing a number within the same area code, only the subscriber number is required. For example, if the local number is 1234, you would dial 1234.
• National calls (from other Uruguayan cities): Dial the national trunk prefix 0, followed by the area code 4364, and then the subscriber number. For instance, to reach a Trinidad number from Montevideo, you would dial 0 4364 1234.
• International calls (from outside Uruguay): Dial the international access prefix (e.g., 00 from most countries), followed by Uruguay's country code +598, then the area code without the leading zero, and the subscriber number. For example, from the United States, you would dial 011 598 4364 1234; from most European countries, 00 598 4364 1234.

Numbering Structure and Overlay Considerations

Uruguayan fixed-line numbers typically consist of 8 digits in total, including the area code. For the 4364 code, subscriber numbers are usually 4 digits long, resulting in a complete national significant number (NSN) of 8 digits (4364 + 4 digits). Currently, there is no overlay code for Trinidad; the 4364 code is exclusively used for this geographic area. However, as with all fixed-line services in Uruguay, number portability allows subscribers to retain their numbers when switching between fixed-line operators.

Important Notes for Callers

When calling from a mobile phone within Uruguay, you must still include the national trunk prefix (0) and the area code, as mobile numbers are non-geographic and require full national dialing. For international callers, it is essential to omit the leading '0' of the area code when using the +598 country code. Always verify the current dialing procedures with your service provider, as international dialing formats can vary by country.
