Area Code 39 – Yby Ja'U

Overview of Paraguay Area Code 39

Area code 39 is a geographic National Destination Code (NDC) within the Paraguayan national numbering plan, assigned to the district of Yby Ja'U (also spelled Yby Yaú) and its surrounding administrative area. Yby Ja'U is a district located in the Concepción Department, in the northern part of the country, near the Brazilian border. This code is used for fixed-line (PSTN) services within this specific locality.

Geographic Coverage and Administrative Jurisdiction

The 39 code covers the urban and rural areas of the Yby Ja'U district, which serves as the local exchange area. The district is known for its agricultural activity and its proximity to the border with Brazil, which influences cross-border communications. The administrative jurisdiction falls under the municipality of Yby Ja'U, which is part of the Concepción Department. The code is not used for mobile services; mobile numbers in Paraguay are identified by different prefixes (starting with 9 or 8) and are non-geographic.

Dialing Formats and Instructions

To call a fixed-line number in Yby Ja'U, the following formats apply:

• National dialing (within Paraguay): Dial 0 (trunk prefix) followed by the area code 39 and the subscriber number. For example, if the local number is 456789, you would dial 039 456789 from other parts of Paraguay.
• International dialing (from outside Paraguay): Dial the international access prefix (e.g., 00 from most countries, or + from mobile), then Paraguay's country code 595, then the area code 39 (without the leading 0), and then the subscriber number. For example, from the United States, you would dial 011 595 39 456789 or +595 39 456789 from a mobile phone.
• Local calls (within Yby Ja'U): For calls within the same area code, it is often possible to dial only the subscriber number, but it is recommended to use the full national format to avoid confusion, especially with the increasing use of VoIP.

Overlay and Numbering Considerations

As of the latest ITU-T E.164 guidelines, Paraguay has not implemented overlay codes for this area. The 39 code is exclusively assigned to Yby Ja'U. However, with the growth of telecommunication services, it is advisable to always use the full national number (including the area code) even for local calls, to ensure proper routing and to prepare for any future numbering changes.

Caller Instructions

For local callers (within Paraguay): Always include the trunk prefix 0 and the area code when dialing from a different region. For example, to call a Yby Ja'U number from Asunción, dial 039 456789. For international callers: Use the country code +595, then the area code 39 (without the leading 0), and the subscriber number. Ensure you have the correct international exit code for your country. For example, from the UK, you would dial 00 595 39 456789.

This area code is part of the geographic numbering plan, and calls to it are typically charged at standard national rates when dialed from within Paraguay. International rates apply when calling from abroad.
