Short answer
Yes, the order number is the key reference for support and order recovery. Keep it until delivery is complete, because it is the fastest way to trace a purchase if you lose the open checkout tab.
Best next step
- Use the matching reference page Open the linked docs or trust page below instead of guessing the next step from memory.
- Keep the order number if payment or delivery is involved That is the fastest way for support to trace what happened without asking you to repeat the whole story.
- Escalate early if the answer does not match your live case If your real order, setup, or delivery state looks different, switch to support quickly instead of waiting for the issue to compound.
