Phone Numbers
A phone number is a unique sequence of digits assigned to a telephone line, allowing individuals to make and receive calls. Typically, phone numbers vary in length depending on the country and can include area codes that designate specific geographic regions.
Phone numbers can be classified into different types, such as landline numbers, which are connected to a physical line, and mobile numbers, which are associated with cellular devices. In addition to voice calls, phone numbers can also be used for text messaging and other communication services.
