How is my name spelled in the translation — and must it match my passport?

In-depth Answer

Romanising Thai has no single right answer.

The Royal Institute system yields one result; a passport may carry whatever spelling the holder chose on their first book.

So one name can legitimately appear as Suphaphon or Supaporn — near-identical to the ear, but two unequal strings to an immigration matching system.

The practice to adopt is simple: attach the passport bio page to every translation order, and if documents were translated on separate occasions, verify that all of them use one spelling.

Where an older file differs, the cleanest option is to re-order that translation so the set is internally consistent, because explaining the discrepancy by covering letter costs far more time.
