I found that writing a comment in the id field label of the upload wizard drastically reduced the number of incorrect id's last year. See e.g. https://commons.wikimedia.org/wiki/MediaWiki:Mwe-upwiz-campaigns-wlm-se-bbr-id/en

So assuming your id's always take a similar format you could just say something like "should be numbers and look like XX-XXX-XXXX"

Hi, everyone,

Recently I noticed that some participants do not place ID of a
monument correctly.š For example in this photo [1] ID isš marked as
"Ship_sunk_sev [2]", but it is not correct. Correct number of this
monument (if I dont mistake it is this one [3]) must be 85-002-0003
(according to our list [4]). Imho this participant was too lazy to

find a correct ID and wrote something by hart :)) though most of our
participants are accurate with ID

What is recommended to do in this case?
š
Just to correct an ID. If you notice that one participant systematically fails to provide a correct ID, they may require some explanations on their talk page.

Cheers
Yaroslav
