The NHS scan may not tell you, a private clinic often will. Here is how to turn a sealed envelope into a reveal your nan in Leeds and your sister in Sydney can share at the same moment.

Short answer: after a private scan in the UK, ask the clinic to put the result in a sealed envelope, keep it closed, then create a free party on Diaper Reveal, enter the result in private and send relatives the link or 6-letter code. They join on their own phones from any country, no app and no account, and the result opens for everyone at the same moment.
Why UK parents end up with a secret in an envelope
The NHS 20-week scan is offered between 18 and 21 weeks, and you may be asked whether you want to know the sex, but some hospitals have a policy of not telling. Many parents therefore book a private scan or a blood test instead. Clinics will usually write the result down, so you walk out holding a secret. The question is how to share it with the people who cannot be in the room.
Ways to reveal it, compared
| Option | Cost | Works for family abroad? | Everyone sees it at the same moment? |
|---|---|---|---|
| Open the envelope at the clinic and phone round | Free | Yes, but they hear it second-hand | No, you tell people one by one |
| Family group chat message | Free | Yes | No, people read it at different times |
| Posted card or balloon box | Cost of the goods and postage | Slow and unreliable across borders | No |
| Video call only (Zoom, FaceTime, WhatsApp) | Free | Yes | Depends on screen-share delay |
| Diaper Reveal live party | Free to host and to join | Yes: link or 6-letter code, no app, no account | Yes, the result opens live on every device |
How to do it in 6 steps
- Ask the clinic for a sealed envelope (or a note in a closed box) so nobody, including you, knows until you choose.
- Create a free party on the create page and enter the result in private. Only you see it until the reveal.
- Pick a time that works in every time zone. A Saturday evening in the UK is morning in the US and the next day in Australia, so write each local time in the invitation.
- Send the link or the 6-letter code in the family WhatsApp group or by text. Give the code to grandparents who type on a tablet.
- Open the call if you like, and let everyone guess pink or blue and play the short games on their own phones while you wait for the stragglers.
- Reveal live. Open the envelope on camera, or let the result open for everyone at once, then take a screenshot of the reactions.

Tips that help UK families
- Do not open the envelope in the car park. Decide the reveal time first, then let the envelope wait.
- Tell only one trusted person, such as a sibling, if you need someone to buy the cake or balloons in the right colour.
- Ask how sure the clinic is. A scan can be wrong, so keep the party light-hearted.
- Keep it to about 20 minutes. That suits children and older relatives.
