Area Code 2221 – Magdalena/Verónica, Buenos Aires

Overview of Area Code 2221

Area code 2221 is a geographic National Destination Code (NDC) assigned to the northeastern part of Buenos Aires Province, Argentina. It covers the administrative districts of Magdalena and Verónica, along with smaller surrounding localities such as Atalaya and General Mansilla. This region lies approximately 100 km southeast of the Autonomous City of Buenos Aires, along the Río de la Plata coastline.

Geographic Coverage and Jurisdiction

The code serves the partido (department) of Magdalena, which is part of the Greater La Plata metropolitan area. Key towns include:

• Magdalena – the administrative seat, known for its historic center and riverside promenade.
• Verónica – a growing town near the Samborombón Bay, with residential and agricultural zones.
• Atalaya – a coastal locality popular for weekend tourism.

All fixed-line services in this area are operated by licensed local exchange carriers, and numbers are used for both residential and business PSTN lines.

Dialing Formats

For callers within Argentina, the national trunk prefix 0 is used, followed by the area code and the subscriber number. The subscriber number in this region has 7 digits.

• National dialing (from other Argentine provinces): 0 2221 4XX XXXX
• Local dialing (within the same area code): 4XX XXXX (omitting the trunk prefix and area code)
• International dialing (from outside Argentina): +54 2221 4XX XXXX

Example: For a fixed line in Magdalena with subscriber number 456 7890, a caller from Buenos Aires City would dial 02221 456 7890, while an international caller would dial +54 2221 456 7890.

Overlay and Numbering Changes

As of 2025, there is no overlay code for 2221; the area code remains the sole NDC for the region. However, due to the growth of VoIP and mobile substitution, some businesses may use non-geographic numbers (e.g., 11 or 15) for customer contact, but fixed-line numbers in this area retain the 2221 prefix.

Caller Instructions

• Local callers within the Magdalena/Verónica area can dial the 7-digit subscriber number directly without the area code.
• National callers from other Argentine cities must include the trunk prefix 0 and the area code 2221.
• International callers should replace the trunk prefix with the Argentine country code +54 and omit the leading 0 of the area code.

Always verify the subscriber number length, as some older lines may have fewer digits, but the standard is 7 digits after the area code.
