What is a phone number?
A phone number is a unique combination of digits assigned to mobile network subscribers so they can communicate through calls or text messages. You use phone numbers in your mobile marketing initiatives to send your subscribers marketing messages via SMS and MMS.
Phone number formats vary across different countries, but the US and Canada use the North American numbering plan, which consists of ten digits.
What does a valid phone number consist of?
To understand the components of a standard phone number, see the table below:
| Component | Description |
| Country code | This is a unique code the International Telecommunication Union assigns to each country. The US and Canada share the country code +1. |
| Area code | This three-digit number identifies the state or region the phone number is from. The Federal Communications Commission assigns the area codes. |
| Subscriber number | This seven-digit number identifies a specific phone line within the area code. |
For example, in the phone number +1-213-555-1234, +1 is the country code, 213 is the area code, and 555-1234 is the subscriber number.
