Four formats. Sequential numbering is what turns a printed card into a ticket, and on anything with a stub the same number appears on both halves, that matching pair is how a draw is verified or an entry reconciled. Filter by how the ticket is used.

Compact, perforated, numbered: event entry, torn at the door.

Matched numbers, both halves. A drawn stub must find its owner.

Your size, numbering, security. Presets or numbering do not fit.

Larger, writable stub, someone writes a name on the stub.
For event entry, a compact numbered ticket with a perforated stub is what people expect and what tears cleanly at a door. For a draw, the stub has to be written on, and a standard stub is too small for a legible name and phone number, which is exactly why jumbo formats dominate raffles. An illegible stub cannot be contacted, which defeats the point of collecting it.
Two specification details matter more than they look. The perforation tie length is tuned to the stock: too short and tickets separate in the box before they are sold, too long and the stub tears raggedly. And security only needs to cost more than the ticket is worth. Numbering plus one foil or spot-color element is enough for most events. If you are continuing a numbering series, tell us the last number issued so the sequence stays unbroken.
