Area Code 436 – Durazno

Geographic Overview

Area code 436 is a geographic National Destination Code (NDC) assigned to the city of Durazno, the capital of the Durazno 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 the city and its immediate surroundings. The region is known for its agricultural production and hosts the annual Semana de la Cerveza festival, attracting visitors who may need local contact numbers.

Dialing Formats

When calling a fixed line in Durazno from within Uruguay, subscribers must dial the national trunk prefix 0, followed by the area code 436 and the subscriber's 6-digit local number. For example, a local number such as 123456 would be dialed as 0 436 123456 from other parts of the country. From abroad, callers must use the international access code (typically 00 or +), followed by Uruguay's country code 598, then the area code without the leading zero, and the local number: +598 436 123456.

Local Calling and Overlays

Within the Durazno exchange area, calls between fixed lines may require only the 6-digit local number, depending on the operator's configuration. However, for clarity and to avoid misdialing, it is recommended to always use the full national format (0 436 XXX XXX) when calling from mobile networks or other regions. As of now, there are no overlay codes in Durazno; the 436 code serves exclusively this geographic area. The number length is fixed at 8 digits (including the area code) for national dialing.

Caller Instructions

• Local callers (within Durazno): If your phone line is provisioned in the same exchange, you may dial only the 6-digit subscriber number. If unsure, dial the full national format.
• National callers (outside Durazno): Dial 0 436 [local number] from any fixed or mobile line in Uruguay.
• International callers: Dial +598 436 [local number] (omit the initial 0).

Technical Considerations

Fixed-line numbers in Uruguay are traditionally associated with copper or fiber-optic PSTN networks, but they can also be ported to VoIP providers. When ported, the geographic significance may be retained for routing purposes, but the service becomes location-independent. Callers should be aware that international roaming or VoIP services may apply different tariffs. For emergency services, always dial 911 (national emergency number) regardless of the area code.
