📍 Geographic Location of Guadalajara
Geographic Significance and Coverage
Area code 849 is a geographic National Destination Code (NDC) within the Spanish national numbering plan, administered under the country code +34. It serves the province of Guadalajara, located in the autonomous community of Castilla-La Mancha, northeast of Madrid. The code covers the capital city, Guadalajara, as well as surrounding municipalities and rural areas within the provincial boundaries. As a geographic prefix, 849 is tied to the PSTN (Public Switched Telephone Network) and is used for fixed-line services, including traditional copper lines, fiber-optic connections, and some VoIP services that are assigned geographic numbers.
Dialing Formats and Instructions
For callers within Spain, the national dialing format requires dialing the full nine-digit number, which includes the area code followed by the subscriber number. For example, a local number in Guadalajara might be 849 XXX XXX. Since Spain uses a closed numbering plan, the trunk prefix '0' is not used; callers simply dial 849 followed by the seven-digit local number. For international callers, the format is +34 849 XXX XXX (or 0034 849 XXX XXX from many countries). It is important to note that the area code is an integral part of the number and cannot be omitted even when dialing locally.
Administrative and Regulatory Context
The Spanish numbering plan is regulated by the Comisión Nacional de los Mercados y la Competencia (CNMC). Geographic codes like 849 are allocated to specific provinces, and numbers within these codes are typically assigned to fixed-line operators. In recent years, number portability allows subscribers to retain their 849 numbers when changing providers, but the geographic association remains tied to the original location. There is no overlay code for Guadalajara; the 849 prefix is exclusive to the province, and all fixed-line numbers in the area are under this code.
Practical Information for Callers
For businesses and residents in Guadalajara, having a 849 number establishes a local presence and can reduce costs for local callers. When calling from mobile phones within Spain, the same dialing rules apply, and charges are typically based on the caller's tariff, not the destination. For those outside Spain, it is essential to use the international prefix of the originating country (e.g., 011 from the US, 00 from most European countries) followed by 34 and the full number. Always verify the number length: 849 numbers have a total of nine digits after the country code, so a complete international format would be +34 849 123 456.
