On another thread an event to be held on Duckett's Common gives its address as N15 3DX.
Must be some mistake I thought.
However, on checking, it seems that perhaps nobody knows.
Freemaptools.com has it that the N8/N15 dividing line runs through the middle of at least part of the park.
free-postcode-maps.co.uk insist that the park is wholly within N8.
NPE Maps have it, (I think!), as N8.
The Council, bless their little cotton socks, are just all at sea and give its address as N4.
The postcode used by the event owners has, I imagine, come from some bum info on Google Maps.
The Royal Mail's Postcode Finder, say that N15 3DX only applies to two addresses - and I guess they ought to know if anyone does.
So do parks have postcodes? I rather think not. The Royal Parks website may give some clues as to why postcodes are sometimes used for parks. In its section on Hyde Park, it offers the following:
If you are using a mobile device, the postcode for the park is W2 2UH, but note this is for guidance only as the park covers a large area.
Despite their obvious confusion, I think the Council might be on the right lines. A park may be within the boundaries of a postal area but I don't believe it has an allocated postcode.
That still leaves the question of which postcode area the park is in (and leaves me scratching my head and wondering why I give half a damn!).
I would have said it’s the tube station post code but on checking it’s N15 3NX.
Postcodes are assigned specifically to addresses that receive post so assume open areas like parks and woodland have never had postcodes. I think you have to go back pre postcodes to old boroughs and parishes to see where the park lies eg Hornsey or Haringey and then use the current nearest postcode.
That's roughly what I thought about the allocation of a postcode.
With regards to the correlation of postcodes with old borough boundaries, I'm not sure it works out that neatly. For example if you look at the N*/N15 boundary through the centre of Harringay, that doesn't match the old Totteham/ Hornsey boundary. As for the N4 boundary, that doesn't really match anything.
My understanding of how the codes developed is that they were instituted in London as larger letter code only divisions in the mid-nineteenth century. At that point all of present-day Haringey was in the Northern, or 'N', district. In 1917 those letter codes were subdivided into numbered sub-areas to improve efficiency. As I understand it, the boundaries had little or no relation to the boundaries of any civil administration, past or present.
Just looking for something unrelated to this discussion, I came across the following on Wikipedia, referring to the organisation of the postal districts of London.
The Northern head district was designated as N1 and the rest of the numbering followed the alphabetical order of the other districts' main names.
So THAT's how the numbers were decided!
Streetmap has Ducketts Common in N8 http://www.streetmap.co.uk/map.srf?x=531543&y=189465&z=106&...
Also your little map for free-postcode-maps.co.uk shows Alexandra Palace in N10. It has a postcode - N22 7AY so wouldn't necessarily trust that map.
I've always thought it's in N8.
I think the freemaptools data is suspect. Streetmap is very probably more reliable since its data comes from Openstreetmap (to which I am a contributor) and the government. I had trouble finding a reliable source of postcode data. So thanks for digging that one up.
I've submitted a change to Google Maps, but it needs to be reviewed (which may mean that it will be picked up sometime or never).
Interesting in that the N4/N8 dividing line seems to go straight through our house at the bottom of Seymour Road. It might explain why our post code was N8, while all my school friends at South Harringay were N4.
The house I grew up in was in Sunderland and the back garden in South Tyneside.
I had always assumed that the boundary between N15 and N8 ran down Green Lanes from the end of West Green Road to Turnpike Lane. I used to go that way to school, but that wasn't yesterday!
I see on free-postcode-maps.co.uk they have somewhere called Ducketts Green - anyone know where that is.
For what it is worth I believe the London codes were in existence long before the addition of the postal codes as such. Ducketts was always in N8 so far as we were concerned back then BUT that was before the postal codes system. Looking at the state of its now I would say if it isn't landscapped pretty sharp someone will want to build on it!
Yes, Duckett’s Green is the historic name for what was embarrassingly rechristened Green Gate Common a few years back. It’s the green bit opposite Duckett’s Common to the east of Green Lanes. “Duckett’s Common” is a relatively modern confection. Like all the commons in the area, it was called a green.
As with Wood Green and other greens around, Duckett’s Green gave it’s name to the area nearby. In this case the area just to the north of the green.
