A landline number is a telephone number associated with a physical phone line, typically connected to a home or office. These numbers are part of a traditional telephone system that uses copper wires or fiber optics to transmit voice signals. Landline phones are often more reliable than mobile phones, especially in areas with poor cellular coverage. Landline numbers are usually assigned by local telephone companies and can be used for various services, including voice calls and faxing. Unlike mobile numbers, landline numbers are tied to a specific location, making them useful for emergency services and local businesses to establish a presence in their community.
