What does random writing on an entry stamp in Thailand mean?

Many expats have observed that their entry stamps upon arriving in Thailand sometimes contain additional writing, which can cause confusion. This extra writing is typically normal and might indicate the page number where the visa is located within the passport, such as "Visa P.20". Several responses from the community confirm that such stamps are common and not a cause for concern. Even if the immigration officer appears disorganized, it doesn't indicate any problem with your visa.
