Geographic Coverage and Administrative Jurisdiction

The area code 37 covers the urban area of Capitan Bado and its rural surroundings, including communities such as Palo Santo and Estrella.

The code is exclusively used for geographic fixed-line numbers, meaning that the number is tied to a physical location.

Dialing Formats and Caller Instructions

Technical Considerations

Fixed-line numbers under area code 37 are typically 6 to 7 digits long, depending on the number of subscribers in the area. The numbering plan follows the ITU-T E.164 recommendation, ensuring global interoperability. Calls to this code are routed via the Paraguayan PSTN, and the service is provided by the state-owned operator Copaco and other licensed fixed-line carriers. As with all geographic numbers, the tariff for calling depends on the caller's location and service provider.

For international callers, it is essential to check the correct time zone (PYT, UTC-4, or PYST, UTC-3 during daylight saving) to avoid disturbing recipients. Additionally, some numbers may be used for fax or internet services, but they remain geographically fixed.
