On Pronoscore IA, a coupon code identifies a selection or slip to find with the relevant partner. A promotional code belongs to an offer or registration. They are not interchangeable even when displayed on the same card.
Putting it into practice
Check which bookmaker the code belongs to and which field receives it. After opening a slip, reread every fixture, market and price: a shared code guarantees neither availability nor success.
What to watch for
Take time to verify the information displayed before proceeding. A dated screenshot can help you retrieve the terms you read, but it does not replace the applicable rules. If information is missing or contradictory, ask the relevant support team instead of assuming the favourable interpretation applies.
