Where is the 01686 area code?

The 01686 dialling code is the UK geographic area code for Llanidloes. Because 01686 is a geographic (01/02) code, a number using it is tied to the Llanidloes dialling-code area — though with modern hosted telephony (VoIP) a business can keep a 01686 number after moving premises, so the code reflects the number’s designated area rather than a guaranteed physical location today.

Ofcom currently lists 532 number blocks under 01686, of which 158 are allocated to 87 communications providers.

Llanidloes phone number format

A Llanidloes number is made up of a 5-digit area code followed by a 5 or 6-digit local number. Written in full it looks like 01686 XXXXXX (the Xs stand for the local digits). Ofcom has not reserved a fictitious drama range for 01686; for on-screen examples it recommends the unused 01632 96000001632 960999 range.

Numbers are frequently moved (ported) between providers, and no public database reveals the person or business behind a specific number, so treat any service that claims to with suspicion.

Spotting spoofed 01686 scam calls

Fraudsters frequently spoof local dialling codes, faking the caller ID so a scam call appears to come from a Llanidloes (01686) number you might trust. Remember:

  • A familiar 01686 area code is not proof the caller is local or genuine — caller ID can be faked.
  • Banks, HMRC and the police will never ask you to move money or share passwords or one-time codes over the phone.
  • If a call feels off, hang up, wait a moment, and call the organisation back on a number from their official website or your statement.
  • Report nuisance calls to the ICO and forward scam texts to 7726 (free).
