Usage of PTCL Area Code

When placing a call within the same area code, the caller does not need to dial the area code. However, when making a call to a different area code, the caller needs to include the area code in addition to the local number.

For example, if calling within the same city with area code 042 (Lahore), one would only dial the seven-digit local number. But when calling from Lahore to Karachi with area code 021, one would dial 021, followed by the seven-digit local number.
