📍 Geographic Location of Beja
Geographic Overview
The +351 284 area code is a geographic National Destination Code (NDC) assigned to the Beja district in the Alentejo region of southern Portugal. This code covers the city of Beja, the district capital, as well as surrounding municipalities and towns, including Aljustrel, Almodôvar, Castro Verde, Ferreira do Alentejo, Mértola, Ourique, and Serpa. The region is known for its agricultural landscape, historical sites, and growing tourism sector.
Dialing Formats
When calling a fixed-line number in the Beja area from within Portugal, you must dial the national trunk prefix 0 followed by the area code and the subscriber number. The complete national format is: 0 284 XXX XXX. For example, a local number might be dialed as 0284 123 456.
For international callers, the format changes: you dial the international access prefix (typically + or 00), then the country code for Portugal (351), followed by the area code without the leading zero, and the subscriber number. Thus, the same number would be dialed internationally as +351 284 123 456.
It is important to note that Portugal uses a closed dialing plan for fixed-line numbers, meaning that the area code must always be dialed, even for local calls within the same geographic area. This is because number portability allows subscribers to retain their numbers when switching providers, so the area code is no longer strictly tied to a physical location.
Administrative and Regulatory Context
The 284 code is regulated by ANACOM, the Portuguese national communications authority, and follows the ITU-T E.164 international numbering plan. As a geographic code, it is primarily associated with traditional PSTN (Public Switched Telephone Network) services, but it may also be used by VoIP providers that offer fixed-line services in the region. Since 2001, number portability has been mandatory in Portugal, allowing users to keep their 284 numbers when changing operators, which can occasionally lead to numbers being served by infrastructure outside the traditional geographic area.
Practical Guidance for Callers
For local callers within Portugal, always include the 0284 prefix when dialing any Beja fixed-line number. For international callers, use +351 284 followed by the subscriber number. Be mindful of potential higher tariffs when calling from mobile networks or from abroad, as international rates apply. If you are unsure about the correct number, verify with the recipient or consult a reliable directory service.
