What should I do if there is a small error on my Thai visa regarding my date of birth?

The user is concerned about a small error on their 90-day Thai visa where the date of birth is recorded incorrectly by one year. Responses in the comments suggest that such minor errors typically do not cause issues at entry; however, it's advisable to print the electronic visa and present it along with the passport at immigration. There is also a concern that the embassy may not correct the mistake once the visa is issued and might require the user to apply for a new visa, potentially incurring additional costs. It is also suggested to contact the consulate for guidance, as the error might pose risks for future visa extensions.
