Q: Given a travel related situation, and given a specific question about the situation, summarize the question into a title
Following this question, I had a refused entry in the UK before (about two years ago) and granted a temporary admission.

I am just curious, what does this stamp below mean? (there two stamps, what I am asking is the top stamp). What is this 45 XXX on the stamp for? I can hardly see any readable word on the stamp!

When I left EU via Amsterdam, the officer asked me what that is and I could not answer him. So I just told him that it was the date I left the UK.

Any ideas?

EDIT: Sorry I think the code/ number should not be shown in this public space.
