📍 Geographic Location of Chaves
Geographic Scope and Administrative Jurisdiction
The +351 276 country-code prefix is a geographic National Destination Code (NDC) assigned to the northern Portuguese district of Vila Real, specifically serving the municipality of Chaves and its surrounding areas. This includes the urban center of Chaves, as well as smaller civil parishes (freguesias) such as Vidago, Oura, and Ervededo. The code is part of the Portuguese public switched telephone network (PSTN) and is administered by ANACOM, the national regulatory authority.
Dialing Formats and Caller Instructions
For local callers within Portugal, the number is dialed as 276 XXX XXX (nine digits in total, including the leading '2'). For international callers, the full E.164 format must be used: +351 276 XXX XXX. When calling from a foreign country, replace the international access prefix (e.g., '00' or '+') with the appropriate code for the originating country. For example, a caller from the United Kingdom would dial 00 351 276 XXX XXX, while a caller from the United States would dial 011 351 276 XXX XXX.
Overlay and Numbering Considerations
As of the current numbering plan, there is no overlay code for the Chaves area; the 276 prefix is exclusively used for this geographic region. However, number portability allows subscribers to retain their 276 numbers when switching operators, even if they move outside the geographic area, which can occasionally lead to a 276 number being associated with a different physical location. Callers should be aware that the prefix does not guarantee the caller's physical presence in Chaves.
Services and Usage
The 276 prefix is primarily used for fixed-line telephony, including residential and business lines. It also supports ISDN and some VoIP services that are registered to the geographic area. Emergency services (112) and national short codes are not affected by this prefix. For businesses, having a 276 number can establish a local presence in the Chaves region, which is particularly valuable for companies targeting the local market.
