Area codes are used to route phone calls to a specific geographic area within a country. All area codes in the United States are exactly 3-digits long.

In the past, a given region often had just one area code. Nowadays, many cities and towns in denser urban areas, including Houston, have 2 or more area codes.

To make an inbound international call (or domestic long distance call) to a Houston landline or mobile phone, you need to dial the appropriate 3-digit area code, followed by a 7-digit local subscriber number.

If you don't have a fully specified 10-digit phone number, including area code, you will not be able to complete an inbound call.

City Codes vs. Area Codes

In some cases, area codes may be referred to as city codes. However, a 'city code' more correctly refers to the codes used to designate airports and other geographic locations. These codes are issued under the United Nation's UN/LOCODE system and/or the IATA airport coding system. The city code for Houston is HOU.
