This one is just bizarre. It seems that FindmyPast (www.findmypast.co.uk) has apparently now restricted access to National Archives reference numbers on preview screens for its 1939 National Identity Register collection searches for England and Wales - but seemingly only on the British version of the site.
Until a short time ago, when carrying out a search, a list of search results would arrive allowing you to see a preview of an individual's specific entry. This preview screen popped up with a name, birth year, an idea of how many others may have been in the household, and the TNA reference number in which the record was held. This same reference number could then be used to identify to an extent which other members might be present in the house, and indeed, on the same street, which could help inform the user as to whether they had indeed found the right household.
Now when you do the search on the UK site, this is what you get:
Both the Australasian and Irish versions of the site are still also displaying the TNA reference numbers.
Quite why FindmyPast seems to be playing silly buggers on this is a mystery. But it may well be the case that the international versions of the site soon implement the same restrictions, so if you have searches to carry out, I would humbly suggest you do them sooner rather than later. If you have one of the international versions of the site open at the same time when you are using the UK site, you can cross reference any possible finds by carrying out the same search on the overseas site, and getting the relevant reference from there - you do not need to be registered or logged in to these overseas versions, the 1939 search will provide these basic preview details for free.
The overseas sites are as follows:
Why FindmyPast is doing this is beyond me - but one has to wonder in which chapter of the customer relations book that they seem to be using was this considered a good idea.
