Where is the 01290 area code?

The 01290 dialling code is the UK geographic area code for Cumnock. Because 01290 is a geographic (01/02) code, a number using it is tied to the Cumnock dialling-code area — though with modern hosted telephony (VoIP) a business can keep a 01290 number after moving premises, so the code reflects the number’s designated area rather than a guaranteed physical location today.

Ofcom currently lists 379 number blocks under 01290, of which 112 are allocated to 90 communications providers.

Cumnock phone number format

A Cumnock 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 01290 XXXXXX (the Xs stand for the local digits). Ofcom has not reserved a fictitious drama range for 01290; for on-screen examples it recommends the unused 01632 96000001632 960999 range.

Who holds 01290 number ranges?

Ofcom allocates 01290 numbers to providers in blocks. These providers hold the largest allocations under 01290:

Ofcom’s data shows the provider each number range was originally allocated to — not who holds an individual number today. 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.

Call charges for 01290 numbers

Calls to 01290 geographic numbers are charged at your phone provider’s standard UK landline rate and are normally included in inclusive call minutes.

Spotting spoofed 01290 scam calls

Fraudsters frequently spoof local dialling codes, faking the caller ID so a scam call appears to come from a Cumnock (01290) number you might trust. Remember:

  • A familiar 01290 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).
