An 8-digit phone number generally consists of a prefix and a subscriber number. The prefix identifies the region, service provider, or type of service, while the subscriber number is unique to the individual user.
For example, in Singapore:
Mobile numbers often start with 8 or 9 (e.g., 9123 4567).
Landline numbers may begin with 6 (e.g., 6123 4567).
This structured approach helps telecom operators nurse database route calls correctly and ensures efficient use of available numbers. Additionally, many countries include area codes or country codes when dialing internationally, but the core local number remains 8 digits long.
