How long does a Webfile stay valid?
30 days. A Webfile older than 30 days is not accepted when you book an appointment.
In detail
The portal FAQ says the Webfile uploaded for an appointment booking must not be older than 30 days. The portal does not accept a Webfile older than that.
Our reading: the FAQ does not say up to which date the 30 days are counted. We read it as the age on the day of upload — from the day the Webfile was generated to the day you book, not to the appointment date. That is our interpretation, not a written rule.
Here is where the limit bites: generate the Webfile far ahead of booking and the 30 days may run out; generate it at the last minute and you are rushing inside the 15-minute booking window. Generating it close to the day you expect to book, but before it, is sensible — that too is our advice.
If you fail to secure a slot, every uploaded Webfile is deleted from the system and you upload them again. The FAQ does not say whether the 30-day clock restarts then, and we do not assume it does.
The prep sheet has a small calculator for working this out from dates. Neither date is saved anywhere.
