Area Code 63 – Valdivia, Los Ríos

Geographic Overview and Coverage

Country code +56 corresponds to Chile, and the area code 63 is a geographic National Destination Code (NDC) assigned to the city of Valdivia and the broader Los Ríos Region. This region, located in southern Chile, includes the provincial capitals and major urban centers such as Valdivia, La Unión, Río Bueno, and Paillaco. The code serves both fixed-line PSTN and VoIP services that are geographically associated with the area. When dialing from abroad, the international format is +56 63 followed by the local subscriber number. For domestic long-distance calls within Chile, the trunk prefix 0 is used before the area code, resulting in 0 63 followed by the subscriber number. Local calls within the same area code typically do not require the area code, but this practice may vary depending on the specific telecom operator and the implementation of local dialing rules.

Numbering Structure and Dialing Procedures

Chilean fixed-line numbers in geographic areas are eight digits in length, including the area code. Therefore, a complete national significant number (NSN) for Valdivia consists of the area code 63 plus a six-digit subscriber number. For example, a typical number might be 63 2 12345, which would be dialed internationally as +56 63 2 12345. When calling from a mobile phone within Chile, the same domestic format applies: 0 63 2 12345. It is important to note that Chile has implemented mobile number portability, but fixed-line numbers are generally not portable across geographic regions. Overlay codes have been introduced in some areas, but as of the latest updates, Valdivia and the Los Ríos Region do not have an overlay code, meaning that the 63 code is exclusively used for this geographic area.

Caller Instructions and Considerations

For international callers, the sequence is: international access code (e.g., 00 from most countries, or + from mobile networks), followed by Chile’s country code 56, then the area code 63 without the leading trunk prefix 0, and finally the subscriber number. For example, to call a Valdivia number 63 2 12345 from the United States, you would dial 011 56 63 2 12345. For callers within Chile, dial the trunk prefix 0 before the area code when calling from a different region or from a mobile network. If you are physically in Valdivia and calling a local number, you may be able to dial just the six-digit subscriber number, but this depends on your operator’s local dialing plan. Always confirm with your service provider if you are unsure. VoIP users should ensure that their service provider supports geographic number routing to Chile and that they include the correct country and area codes.
