These postcodes are structurally valid but fictional, for software testing and form design. This is not a Royal Mail postcode lookup: the Kingston upon Hull districts are real, the full postcodes are not assigned to any address.
A random Kingston upon Hull postcode generator combines a real Kingston upon Hull 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 Kingston upon Hull postcode district. There are 9 of them, in the HU postcode area, and they all belong to the HULL post town in East Riding of Yorkshire. 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.

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.
Kingston upon Hull sits in the HU postcode area. Every district below is a real outward code assigned to the HULL post town.
| District | Locality | Structural range |
|---|---|---|
| HU1 | — | HU1 0AA – HU1 9ZZ |
| HU2 | Osborne | HU2 0AA – HU2 9ZZ |
| HU3 | Newland Avenue | HU3 0AA – HU3 9ZZ |
| HU4 | Anlaby Park | HU4 0AA – HU4 9ZZ |
| HU5 | The Avenues | HU5 0AA – HU5 9ZZ |
| HU6 | Newland | HU6 0AA – HU6 9ZZ |
| HU7 | Bransholme | HU7 0AA – HU7 9ZZ |
| HU8 | Sutton | HU8 0AA – HU8 9ZZ |
| HU9 | Marfleet | HU9 0AA – HU9 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 Kingston upon Hull tells you which country's addressing conventions apply, which ceremonial county 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 | HULL | Royal Mail post town, written in capitals on the address |
| Postcode area | HU | The leading letters of every district above |
| Ceremonial county | East Riding of Yorkshire | ONS administrative geography |
| Country | England | One of the four countries of the United Kingdom |
| Region | Yorkshire and the Humber | ONS ITL1 statistical region |
| Dialling code | 01482 | Ofcom National Telephone Numbering Plan |
Royal Mail has not required a county line on addressed mail since 1996. HULL plus a correct postcode is sufficient; East Riding of Yorkshire 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 Kingston upon Hull address is deliverable, that is a licensed Royal Mail Postcode Address File lookup, and no generator can answer it.
The districts are real: all 9 of them are Royal Mail outward codes genuinely assigned to the HULL 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 Kingston upon Hull in a district lookup and passes validation, but it is not a live delivery point and must never be used to send post.
9, in the HU postcode area: HU1, HU2, HU3, HU4, HU5, HU6, HU7, HU8, HU9. That is the count for the HULL 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 "Kingston upon Hull".
HU. The postcode area is the leading letter or letters of the outward code, so every Kingston upon Hull postcode begins HU — for example HU1. The digits that follow identify the district within the area.
This page generates postcodes on their own and explains Kingston upon Hull's district structure. The Kingston upon Hull 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=kingston-upon-hull&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.
