Area Code 3887 – Humahuaca, Jujuy

Overview of Area Code 3887

Area code 3887 is a geographic National Destination Code (NDC) assigned to the northwestern region of Argentina, specifically serving the city of Humahuaca and its surrounding areas within the province of Jujuy. This region is part of the Quebrada de Humahuaca, a UNESCO World Heritage site known for its stunning Andean landscapes and rich cultural heritage. The code is used for fixed-line (PSTN) services, and it is administered under Argentina's national numbering plan, which follows ITU-T E.164 recommendations.

Geographic Coverage and Jurisdiction

The 3887 area code covers Humahuaca and nearby localities such as Uquía, Hipólito Yrigoyen, and Iturbe, all within the Department of Humahuaca. The administrative jurisdiction falls under the province of Jujuy, with the provincial capital, San Salvador de Jujuy, located approximately 130 kilometers to the south. The region is primarily served by fixed-line operators, with coverage extending to rural and semi-urban areas.

Dialing Formats

For local calls within the same area code, callers can dial the 7-digit subscriber number directly (e.g., 456-7890). For calls from other regions within Argentina, the format is 0-3887-456-7890, where the leading '0' is the trunk prefix, and '3887' is the area code. For international callers, the format is +54-3887-456-7890, where '+54' is Argentina's country calling code. It is important to note that when dialing from abroad, the trunk prefix '0' is omitted.

Overlay Considerations

As of the latest numbering plan updates, there is no overlay code for 3887; the area code remains exclusive to this geographic region. However, with the growth of VoIP and mobile services, some numbers may be ported, but the area code itself does not change. Callers should always verify the complete number to avoid misdialing.

Caller Instructions

For local callers within Humahuaca, simply dial the 7-digit number. For callers elsewhere in Argentina, include the trunk prefix '0' and the area code. For international callers, dial the international access prefix (e.g., '00' in most countries), followed by Argentina's country code '54', then the area code '3887' (without the leading '0'), and the subscriber number. For example, to call a Humahuaca number from the United States, dial 011-54-3887-456-7890.

Practical Tips

When saving Argentine numbers in your phone, always store them in international format (+54-3887-...) to ensure proper routing when traveling or using VoIP services. Be mindful that landline numbers in this region typically have 7 digits, while mobile numbers in Argentina are 8 or 9 digits and use different area codes (e.g., 388 for mobile in Jujuy). If you receive a call from an unknown number with this prefix, it is likely a fixed-line call from the Humahuaca area.
