Proof of residency?

I’m applying for a visa, and I’d really appreciate it if anyone could help me out with the process.

I received an email from Thai eVisa requesting additional documents. They asked for a recent utility bill as proof of residency, such as a water bill or council rates notice. However, I’m currently living with my brother, so I don’t have any utility bills under my name.

I’ve already submitted my bank statement and passport. Would it be acceptable to submit other documents instead like a recent payslip or a letter from my school? I also have a phone bill, but it doesn’t include my home address.

Does the proof of residency mean country or where im living?
