Area Code 781 – Santa María / Misiones

Overview of Area Code +595 781

Area code 781 is a geographic National Destination Code (NDC) within the Paraguay national numbering plan, assigned to the locality of Santa María in the Misiones Department. This code is part of the country's fixed-line PSTN infrastructure, managed under the ITU-T E.164 international standard. It serves the urban and rural areas of Santa María and its immediate surroundings, providing local telephony services to residential, commercial, and administrative users.

Geographic Coverage and Administrative Jurisdiction

Santa María is a district in the Misiones Department, located in the southern region of Paraguay. The area code covers the city center and the surrounding rural communities that rely on the local exchange. The Misiones Department is known for its agricultural economy, and Santa María serves as a local service hub. The geographic coverage is limited to this specific area, and calls to neighboring towns such as San Ignacio or Ayolas require different area codes.

Dialing Formats and Caller Instructions

For callers within Paraguay, the national trunk prefix 0 is used before the area code. The national dialing format is:

• 0 781 XXX XXX (where XXX XXX represents the local subscriber number)

For international callers, the country code +595 is used, followed by the area code (without the leading zero) and the subscriber number:

• +595 781 XXX XXX

For example, a local call to a Santa María number would be dialed as 0781 123 456, while an international caller would dial +595 781 123 456.

Numbering Plan and Overlay Considerations

Currently, there is no overlay code for the 781 area. The subscriber numbers within this code are typically 6 digits long, making the total national significant number (NSN) length 9 digits (including the area code). This is consistent with Paraguay's fixed-line numbering plan. No major changes are anticipated in the near future, but users should verify with their service provider for any local dialing adjustments.

Cost and Routing for Callers

Calls to geographic area codes like 781 are generally charged at standard national rates for domestic callers, depending on their operator and plan. International calls to Paraguay are billed according to the caller's international tariff. For businesses or individuals frequently contacting Santa María, using a VoIP service or a calling card may offer cost savings. It is important to note that calls to this number are routed through the public switched telephone network (PSTN) and may be subject to standard call setup times.
