For domestic callers within Türkiye, the national dialing format is 0 464 XXX XX XX, where 0 is the trunk prefix, 464 is the area code, and the subscriber number consists of 7 digits. For international callers, the format is +90 464 XXX XX XX, omitting the trunk prefix. Local calls within the same area code do not require the area code; however, due to the implementation of overlay and number unification, some operators may require 10-digit dialing even for local calls. It is always safe to use the full national format.

The subscriber numbers are 7 digits long, providing a capacity of up to 10 million numbers, though actual usage is lower due to population and demand. The Turkish Information and Communication Technologies Authority (BTK) manages the allocation of numbers.
