How many digits is a mobile phone number?
- Mobile phones use the same area codes as landline telephones, but the number begins with a "15", added to a string of 6, 7 or 8 digits, just as described above. After the "15", the remainder of the number can start with a 3, a 4, a 5 or a 6.
Area codes start with a trunk prefix "0" and extend for up to four digits but usually 3; followed by the local phone number of up to seven digits. In industry jargon, these area codes and prefixes are referred to as NDCs (National Dialing Codes). This is the term used by ComReg and technical documents, as they include non-geographic codes. Historically, like the UK, the term STD code (Subscriber Trunk Dialling) was used.
As of today, the NANP or North American Number Plan supports only 10 digits. The first three digits are the area code. You have the ability to add # at the end of the phone number. It should help speed up the set-up time of the call. If needed, we could go to a four digit area code. There are no plans to migrate to a four digit area code.

In Brazil there are two systems. The first, the Registro Geral (RG) is a number associated to the official ID card. Although the ID cards are supposedly national, the RG numbers are assigned by the states and a few other organizations, such as the armed forces.
