UCAS Place of Birth Question

Basically, my passport and birth certificate have different countries listed for my place of birth and I was wondering which one I should use in my UCAS application, the one on my passport or the one on my birth certificate?
(As for why the information is different: It’s complicated — that’s the only answer I have)

It won’t let me respond directly to anyone for some reason, but here’s a small and vague (because I don’t understand it entirely myself) explanation for the curious:

To answer everyone’s question: It’s not entirely clear to me why the information is different; the one on the birth certificate is the correct information, while the one on my passport is incorrect. We've tried fixing it before, but it's unfortunately been an incredibly stubborn issue lol. They've listed different birthdays before too (fixed now, but just to give perspective).

Also to answer an earlier question: Both the countries very much exist.

Anyways, it looks like I'll just have to contact both UCAS and the universities themselves; thanks to everyone who has responded so far!

In that case I would recommend persisting with getting the passport corrected as any discrepancy between your documents might get picked up by the UK Visa and Immigration service and cause issues.

I’m aware; that’s why I’ve been hesitant with sending in my applications despite being done for a while — I already know what problems this might unfortunately cause me, and whether or not they fix the information is uncertain as it’s been an issue for years. Thanks again though
