In case this happens, one option to be sure is to look for the link that appears in the preview on the internet and verify that it does not have any alert or has been reported.

Do not share data

These codes are also often used in the middle of online shopping processes, however, it is better to avoid those cases because sensitive data is delivered in codes that are open. In that case, it is better to do the process from the official application of the bank or the store.
