This is the part people discover late, usually when somebody senior asks whether the tickets are compliant and nobody knows.
Selling tickets is usually regulated
A free prize draw and a raffle where money changes hands are different things almost everywhere. Once tickets are sold, you are generally running a form of lottery, and it is licensed or registered somewhere.
Who licenses it, and what the ticket must say, varies by country and often by region. That question belongs to your regulator, not to your printer.
The fields to leave room for
The promoter — the organisation running the draw, named. A registration or licence reference. The date of the draw. Any age restriction. Often the price per ticket and how proceeds are used.
Leave room for all of them at layout stage even if you are still confirming the exact wording.
Why layout order matters
Artwork designed first and compliance text added last always ends up as tiny type in a margin. It is technically present and practically invisible, which satisfies nobody.
Our template starts with the fields and lays the design around them. The ticket looks better for it, because the constraint forces a cleaner structure.
What we will and will not do
We will ask you for the wording before printing, lay it out legibly, and proof it back to you.
We will not tell you what your regulator requires, and we would treat any printer who offered to with real suspicion.
