These postcodes are structurally valid but fictional, for software testing and form design. This is not a Royal Mail postcode lookup: the Aberdeen districts are real, the full postcodes are not assigned to any address.
A random Aberdeen postcode generator combines a real Aberdeen postcode district with a generated inward code, producing a structurally valid postcode that is not assigned to any delivery point.
Every postcode on this page starts from a genuine Aberdeen postcode district. There are 10 of them, in the AB postcode area, and they all belong to the ABERDEEN post town in Aberdeen City. The three characters after the space are generated to the Royal Mail format rules, so a result validates in any form or database while belonging to no real property.

For complete Aberdeen addresses — building number, street, locality, post town, Aberdeen City and postcode, laid out to Royal Mail conventions — use the random Aberdeen address generator.
A UK postcode splits into an outward code and an inward code. The outward code identifies the district; the inward code narrows it to a small group of properties. This generator keeps the first half real and generates the second, which is what makes the output safe to use and still valid.
Aberdeen sits in the AB postcode area. Every district below is a real outward code assigned to the ABERDEEN post town.
| District | Locality | Structural range |
|---|---|---|
| AB10 | — | AB10 0AA – AB10 9ZZ |
| AB11 | Torry | AB11 0AA – AB11 9ZZ |
| AB12 | Cove Bay | AB12 0AA – AB12 9ZZ |
| AB15 | Hazlehead | AB15 0AA – AB15 9ZZ |
| AB16 | Northfield | AB16 0AA – AB16 9ZZ |
| AB21 | Dyce | AB21 0AA – AB21 9ZZ |
| AB22 | Bridge of Don | AB22 0AA – AB22 9ZZ |
| AB23 | Bridge of Don | AB23 0AA – AB23 9ZZ |
| AB24 | Old Aberdeen | AB24 0AA – AB24 9ZZ |
| AB25 | Woodside | AB25 0AA – AB25 9ZZ |
The structural range is what the postcode grammar permits for each district, not a list of codes Royal Mail has issued. Which sectors and units are actually allocated is Postcode Address File data, which is licensed and not held here — so a generated postcode inside the range may well be unallocated. For test data that is the point.
A postcode carries more than a location. Reading one from Aberdeen tells you which country's addressing conventions apply, which council area the address sits in, and — if you need a matching telephone number — which dialling code area it falls in.
| Field | Value | Where it comes from |
|---|---|---|
| Post town | ABERDEEN | Royal Mail post town, written in capitals on the address |
| Postcode area | AB | The leading letters of every district above |
| Council area | Aberdeen City | ONS administrative geography |
| Country | Scotland | One of the four countries of the United Kingdom |
| Region | Scotland | The country name |
| Dialling code | 01224 | Ofcom National Telephone Numbering Plan |
Royal Mail has not required a county line on addressed mail since 1996. ABERDEEN plus a correct postcode is sufficient; Aberdeen City is included because plenty of address forms and legacy databases still expect a county.
What they are not for: sending post, verifying an identity, or implying that a property exists. If you need to know whether a Aberdeen address is deliverable, that is a licensed Royal Mail Postcode Address File lookup, and no generator can answer it.
The districts are real: all 10 of them are Royal Mail outward codes genuinely assigned to the ABERDEEN post town. The three characters after the space are generated, so the full postcode is almost certainly not allocated to any property. That combination is deliberate — the result resolves to Aberdeen in a district lookup and passes validation, but it is not a live delivery point and must never be used to send post.
10, in the AB postcode area: AB10, AB11, AB12, AB15, AB16, AB21, AB22, AB23, AB24, AB25. That is the count for the ABERDEEN post town as recorded in this site's registry; a post town does not follow council boundaries, so it may not match what a resident would call "Aberdeen".
AB. The postcode area is the leading letter or letters of the outward code, so every Aberdeen postcode begins AB — for example AB10. The digits that follow identify the district within the area.
This page generates postcodes on their own and explains Aberdeen's district structure. The Aberdeen address generator produces complete postal addresses — building number, street, locality, post town, county and postcode — laid out to Royal Mail conventions. Use this page when you need postcodes to test a postcode field; use the address generator when you need whole addresses.
Yes, with no API key. Call GET /api/v1/postcodes/random?location=aberdeen&count=25 for JSON. Add &seed=1 to get the same set back on every request, which keeps snapshot tests stable. The response carries the outward code, inward code, area, district and sector for each postcode alongside the post town and county.
Structural validation, yes: the format, the length and the excluded letters are all respected, so a correctly written regex or a library check will accept them. A validator backed by licensed Postcode Address File data will reject most of them, correctly, because the full postcode is not an allocated delivery point. If your test suite needs addresses that pass a PAF lookup, no generator can supply them.
Postcodes are generated on demand and never stored. They are for software testing and development only, and must not be used to send post, to imply a real address, or for identity verification.
