According to ALLCITYCODES.COM, United States (US) has an area code of +1. This is the same as the country code for US and it is used for both landline and mobile phone numbers. The area code comprises of three digits, which indicate the region or city to which the phone number belongs. For example, if it starts with ‘212’, then it’s a landline number in New York City, while if it starts with ‘206’, then it’s a mobile phone number in Seattle. The area code of US is very convenient because you can use it to call anywhere within the country without having to dial an international telephone number. You just have to dial +1 followed by your desired seven-digit phone number and you will be connected right away. This makes making calls within US very easy and convenient since you don’t have to remember long international numbers every time you want to make a call. Furthermore, this also helps save money since international calls are usually more expensive than local ones. In addition, the area code of US can also be used to make toll-free calls from within the country or outside of it. Toll-free numbers start with 800 followed by six digits that indicate specific services such as customer service or technical support. These services are usually free for customers using US landlines but may incur charges when using mobile phones. The area codes in use in the United States have been standardized by the North American Numbering Plan Administration (NANPA). This organization assigns each region a unique three digit prefix that identifies where a particular call originates from based on its geographic location. NANPA also keeps track of all active area codes in order to ensure that no two regions have identical codes or overlap each other’s service areas. Overall, having an area code of +1 makes making calls from within or outside the United States convenient and cost effective for consumers who want quick access to customer service and other services without incurring high fees associated with international calling rates.
