📍 Geographic Location of Granada
Geographic Overview
The +34 858 prefix is a geographic area code assigned to the province of Granada, located in the autonomous community of Andalusia, southern Spain. This code serves both the capital city, Granada, and the surrounding municipalities within the province. It is important to note that 858 is an overlay code for the older 958 prefix, which means that both codes cover the same geographic area. This overlay was introduced to meet the growing demand for telephone numbers in the region without requiring changes to existing numbers.
Dialing Formats
When dialing a number with the 858 prefix, the format depends on the caller's location:
- Local calls (within Spain): Dial the full 9-digit number, including the prefix. For example, 858 XXX XXX.
- International calls (from outside Spain): Dial the international access code (00 or +), followed by Spain's country code 34, and then the 9-digit number. For example, +34 858 XXX XXX.
Since 858 is an overlay, local calls between 858 and 958 numbers are charged as local calls, and there is no need to dial an additional trunk prefix.
Regulatory and Technical Details
The 858 prefix is part of the Spanish National Numbering Plan, regulated by the Comisión Nacional de los Mercados y la Competencia (CNMC). It is classified as a geographic number, meaning that the tariff for calls to these numbers is based on the caller's location within Spain. However, with the rise of VoIP and mobile services, geographic prefixes are no longer strictly tied to a physical location; they can be used by businesses and individuals who may not be physically present in Granada.
For callers within Spain, dialing a 858 number from a fixed line or mobile phone incurs standard national call charges. For international callers, charges vary depending on their service provider and the country from which they are calling. It is always advisable to check with your telecom operator for specific rates.
Usage and Availability
Numbers with the 858 prefix are assigned to both residential and business subscribers. They are commonly used by local businesses, public administration offices, and private individuals. Due to the overlay, new number assignments in the province may be given either the 958 or 858 prefix, depending on availability.
When calling a Granada number from abroad, it is essential to omit the leading zero that is sometimes used in domestic dialing. In Spain, the national significant number is nine digits, and the country code +34 is used for international calls. For example, a Granada number might be formatted as +34 858 123 456.
