01437 area code
Haverfordwest and Clynderwen
The 01437 area code is for Clynderwern and Haverfordwest, and the surrounding areas.
Locations using 01437 numbers include:
- Broad Haven
- The Rhos
- St Davids
The first digit of the six-digit local number usually indicates more precisely where it is associated with:
|Number range||Primary area*||Other locations served|
|(01437) 2xxxxx||Clynderwen||Llawhaden, Maenclochog|
|(01437) 6xxxxx||Haverfordwest||Broad Haven, Camrose, Clarbeston, Johnston, The Rhos, St Davids, Treffgarne|
* Telephone companies are officially required to issue numbers according to this pattern. Some smaller or newer operators may disregard the rules and use the same series of numbers across the entire area.
Most numbers using the 01437 area code are normal Haverfordwest and Clynderwen landlines but be aware that, as is the case for all UK area codes, such numbers may also be used for services without any physical link to the area. (More info)

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.
