Area code history
Haverfordwest and Clynderwen previously had separate area codes. Numbers from the former Clynderwen 0991 area code were absorbed into the 0437 area code (which later became 01437) sometime before the mid-1990s.
The 0991 prefix was reused for premium rate services later in the 1990s.
