How to say "did I spell your name correctly?" in korean?

Question

Answer

"did I spell your name correctly?" 
=> (내가) 네 이름 맞게 쓴 거니? (casual - between friends)  * 이름 = name.
=> 제가 (선생님/사모님/님) 성함을 맞게 썼나요? (formal and respectful)  * 성함 = name (honorific).

Above sentences are using 맞게 (correctly), which seems to fit the situation best.

If you want to emphasize "spelling", you could say:
- 네 이름 철자[스펠링]를 맞게 쓴 거니? / 성함 철자[스펠링]를 맞게 쓴 건가요?

철자 means "spelling", same as 스펠링 which is borrowed from English.  
Nowadays 스펠링 seems more widely used than 철자.

Answer

내가 너의 이름을 정확하게(맞게) 불렀니? Sorry my english translate not good.
