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.
