📍 Geographic Location of Seville
Geographic Scope and Regulatory Framework
Area code 855 is a geographic National Destination Code (NDC) assigned to the province of Seville, within the autonomous community of Andalusia, Spain. Under the national numbering plan administered by the Comisión del Mercado de los Telecomunicaciones (CMT), now part of the Secretaría de Estado de Telecomunicaciones, this code is allocated for fixed-line PSTN and VoIP services. The code covers the capital city of Seville and its metropolitan area, including municipalities such as Dos Hermanas, Alcalá de Guadaíra, and Utrera, as well as numerous smaller towns and rural districts within the provincial boundaries.
Dialing Formats and Numbering Structure
Spanish fixed-line numbers using the 855 code follow a standard nine-digit national significant number (NSN) format: 855 XXX XXX. When dialed from within Spain, the full nine-digit number is used without any trunk prefix, as the country employs a closed numbering plan. From abroad, callers must dial the international access prefix (00 or +), followed by the country code 34, and then the nine-digit number. For example, a local number in Seville might be 855 123 456, which would be dialed as +34 855 123 456 from any international location.
Overlay and Number Portability
Seville is part of an overlay complex that includes multiple geographic codes, such as 95 (the original Seville code) and 854, 955, and 854. This means that the same geographic area is served by several NDCs, and subscribers may retain their numbers when switching between fixed-line operators, thanks to local number portability. Consequently, a number starting with 855 does not necessarily indicate a specific operator; it is simply a geographic identifier. Callers should be aware that the cost of calling a fixed line in Seville is typically the same as any other national fixed-line call, regardless of the specific geographic code.
Instructions for Callers
For local callers within Spain, dialing a Seville fixed line requires only the nine-digit number. For international callers, the process is straightforward: dial your country's exit code, then 34, then the nine-digit number, omitting any leading zero (none exists). It is important to note that numbers beginning with 855 are not premium-rate or special services; they are standard geographic lines. As with all Spanish fixed numbers, calls are typically charged at standard national rates when dialed from mobile or other fixed lines, and may be included in bundled minute packages.
