Ok, that seems to me like a partial postcode though and therefore much less useful than a full postcode

Hi, what's your basis for these changes?
Everything that I can see that you've changed from trunk to primary should actually be trunk.
See osm.wiki/Roads_in_the_United_Kingdom
for how we tag roads and e.g. the A167, A691 and A693 are all trunk roads by that definition, having yellow on green on the signs.
This can be confirmed by Mapillary photos, but I am also familiar with all of those roads.

A bit of research finds this duplicate: way/101155236
The postcode for this site seems to be PO13 8AS, so maybe it's this instead:
https://environment.data.gov.uk/public-register/waste-operations/registration/DB3901UD-T001?__pageState=result-all

Hi, just wondering what your source is for the postcode?
As that's showing as a long way away from here

No worries
I've set up a Map Roulette challenge to make adding detail to schools easier (which is what I used here)
Check it out if you're interested:
https://maproulette.org/browse/challenges/21922

Originally from https://get-information-schools.service.gov.uk/Establishments/Establishment/Details/136732 (available under OGL)
Then confirmed by the branding on the website
From the gov website you can see under links that the previous establishment didn't have Penrith in the name.

Hmm, I feel that postal_code is only for highways so I wouldn't like adding that.
Feel free to remove addr:postcode here

The postcode had actually previously been added by someone else here.
I agree that it seems like duplication having tags on the building as well as the site outline, but I'm not convinced that it's wrong for the school's postcode to be added to the school outline

Hi, thanks for adding all of these buildings.
It's best to use the address fields, rather than the name when adding the house numbers as that makes them more searchable. Then you can also add the street and postcode if you know them.
I'm fixing some round here.

Thanks

Sure, I think it's best to be explicit though

Hi, thanks for adding this pavement.
Just a few notes, its name isn't "Street Pavement" - that's a description of what it is that is already covered by other tags you've used.
Also, you don't need to set motor_vehicle=no as that is assumed for all paths

Hi, looks like you've got a typo on the postcode here, can you fix it please?

On these two houses
way/911248266
way/911248275
you've put GB as the postcode, I'm sure that was meant for the country, but do you know the actual postcodes?

Something seems to have gone wrong with the postcodes on these, can you retrieve the data?

Hi and welcome to OSM.
You requested a review of this and it mostly looks good to me.
When we tag colours, they should be in all lowercase, I've fixed that for you here.
Happy mapping!

Hi, you requested a review of this change.
Couple of things:
You've tagged this section as a path, but from aerial imagery it looks more like a service road.
Tagging it as private is the right thing if there's no public access, although the gate at the north east end was already tagged as being private (that doesn't mean that the road shouldn't be tagged as private too).
You got a warning about the waterway and path crossing which should be fixed. The A1 above there is mapped as a bridge, so I think the path/road you added should not be a tunnel (like the cycle path next to it isn't).

Hi, you requested a review of this and it seems good to me, if that route isn't used any more.

Hi, you requested a review of this and it all looks good to me. It would be good to add the postcode too, if you know it.

Hi and welcome to OSM!
You requested a review of this, and my only comment would have been about the address, but you've since fixed that, so all looks good to me!
