Are text messages starting with 1068 trustworthy?

Not credible.

The 068 number segment is a nationwide non-commercial short message service number segment, so it can be used by formal organizations and informal organizations. Using a number segment to determine whether a text message is genuine is very unreliable and can easily allow criminals to take advantage of it. The correct approach is to verify the content in the text message and make sure it is consistent with the actual situation. Only then can the text message be true. It is inconsistent with the actual situation and the content inside is incorrect, so it is obviously false.
