01224 area code — Aberdeen: who called, who holds the numbers
What does the 01224 register show?
01224 is the area code for Aberdeen. In the Ofcom numbering snapshot published 23 Sep 2026, 867,000 of its 1,000,000 numbers are allocated, in 363 blocks listed to 90 holders — above the median active UK code (446,000). 5 of its blocks have an allocation date in the last 12 months. Check the number below.
A range holder is the company Ofcom lists for a block of numbers, usually a network or wholesale provider that supplies many businesses. It is not evidence about the range holder or caller, and a displayed caller ID is not proof of who called. If a number rang once and cut off, do not call back.

What should I do after a suspicious call from a 01224 number?
| Step | Action |
|---|---|
| 1 | Do not call back a number you cannot identify. If it rang once and cut off, that is often a test that your line is live. |
| 2 | If the caller said they were your bank, a company or the police, hang up and phone the organisation on a number you find yourself, or call 159 for your bank. |
| 3 | Forward suspicious text messages to 7726, free of charge. |
| 4 | If you lost money or shared details, contact your bank at once and report to Action Fraud (England, Wales and Northern Ireland) or Police Scotland. |
| 5 | For unwanted marketing calls, report to the ICO and block the number on your phone. |
| 6 | Calls to 01 and 02 numbers are charged at your provider’s standard landline rate (gov.uk/call-charges). |

Is a 01224 number real, and what does “Quarantined” mean?
Of the 1,000,000 numbers in 01224, 86.7% are allocated (867,000), 12.0% protected, 1.2% free and 0.1% quarantined in the snapshot published 23 Sep 2026, against 23.8% allocated across all UK geographic ranges. Quarantined means withdrawn and held before reuse, not never allocated; a block’s status does not tell whether one particular number is in service.
| Status | Numbers | Blocks |
|---|---|---|
| Allocated | 867,000 | 363 |
| Protected | 120,000 | 111 |
| Free | 12,000 | 12 |
| Quarantined | 1,000 | 1 |
| Other (Reserved or Designated) | 0 | 0 |

Has anything changed in the 01224 ranges, and which blocks were allocated recently?
Between the weekly Ofcom files fetched on 19 Aug 2026 and 24 Sep 2026 (5 weekly transitions), none of the 487 register blocks of 01224 changed status, holder or listing; the median active code also shows none. Separately, 5 blocks of 01224 have an allocation date in the last 12 months. Block changes are not the same as a number being cut off or ported.
Ofcom: “Please note that transferred numbers will also be shown as ‘allocated’.” (numbering data, ofcom.org.uk, retrieved 24 Sep 2026)
