Door check-in: faster queues, fewer arguments, better data
In this guide
Good door check-in means scanning every ticket once, checking ID quickly, and having a clear process for the problems that always come up: names that don't match, duplicate tickets and guestlist disputes. A fast, fair door keeps the queue moving, cuts arguments, and gives you an accurate record of who actually attended, which is some of the most valuable data a promoter has.
The door is the first and last impression of your night. It's also where your ticket sales turn into real attendance figures. Getting it right is part logistics, part customer service and part data collection.
Key takeaways
- Plan entry lanes and staffing around your peak arrival time, not the average.
- Scan every ticket, including guestlist and comps, so you have one accurate attendance record.
- Write down how you'll handle common problems before doors open, and brief the team.
- Make ID requirements clear in advance. Most door arguments start with a surprise.
- Use check-in data after the event to see who came, who didn't, and who to invite next time.
What is door check-in?
Door check-in is the process of verifying that each person arriving has a valid ticket or guestlist place and recording that they've entered. It usually involves scanning a barcode or QR code on a ticket, checking ID where needed, and marking guestlist names as arrived.
Check-in is separate from security searches and age checks, though at small venues the same people often do all three. Keeping the roles clear helps the queue move.
Before the night: preparation
Work out your peak
Most people don't arrive evenly. A club night might see a rush just after a guestlist cut-off or when the headliner is due; a gig often gets a wave just before the main support. Estimate how many people you expect in the busiest half hour and plan for that.
As a rough guide, one experienced person scanning tickets on a phone can move a steady queue quickly, but ID checks and bag searches slow things down a lot. If you're searching and checking ID for every person, you'll need more staff on the door than you'd think.
Choose your check-in setup
| Setup | Good for | Watch out for |
|---|---|---|
| Ticket platform's own scanning app | Events with a single ticket source | Separate lists for guests and comps |
| A combined check-in tool | Events with multiple ticket sources, guestlists and comps | Needs importing and testing beforehand |
| Printed list | Very small events, or as a backup | Slow, and hard to keep accurate |
Whatever you use, always have a backup. Download or print the attendee list before doors in case of signal problems. Basement venues are notorious for poor mobile reception, so check whether the venue has Wi-Fi the team can use.
Test everything
- Scan a test ticket on every device.
- Check that devices are charged and that you have power banks.
- Make sure every scanner is logged into the right event.
- Check the guestlist is loaded and searchable.
Tell attendees what to expect
Most door problems come from surprises. In the days before, send ticket holders a short "know before you go" message covering:
- Door times and last entry.
- What ID is accepted, and that it must be a physical, in-date document if that's your policy.
- Bag policy and any prohibited items.
- Whether the ticket name must match the ID.
- Whether re-entry is allowed.
See the event marketing timeline for when to send this.
ID checks: the basics
For licensed premises in England and Wales, the mandatory licensing conditions require an age verification policy for alcohol sales, and many venues use Challenge 21 or Challenge 25. The policy usually requires photo ID showing a date of birth and a holographic mark or ultraviolet feature, such as a passport, photocard driving licence or a PASS-accredited proof of age card. Scotland and Northern Ireland have their own licensing rules.
The venue's licence and its policies come first. Check with the venue what ID they accept and whether they have any conditions on entry (such as last entry times or ID scanning), and make sure your messaging matches. This is general guidance, not legal advice.
Lanes and staffing on the night
- Separate lanes where possible. One for tickets, one for guestlist and problems. Guestlist and problem cases take longer and shouldn't block the main queue.
- A queue walker. Someone who walks the line before doors, checking that people have tickets ready and ID out, and turning away people without either before they reach the front.
- A problem resolver. One person (often the promoter) who handles disputes away from the door so scanning doesn't stop.
- Clear signage. "Tickets ready, ID out" and "Guestlist this side" save a lot of repeated questions.
Handling common door problems
Write these down and brief the team before doors.
The ticket has already been scanned
This usually means a screenshot was shared or resold. Check the time of the first scan and the name on the ticket. Have a policy: for example, the person whose name matches the ticket and ID gets in, and anyone else is directed to buy on the door if available. Stay calm; the person in front of you may have been sold a fake.
The name doesn't match
Many platforms allow name changes, and many promoters don't enforce names strictly. Decide your policy in advance and state it in your ticket terms and pre-event messages. Inconsistent enforcement causes more arguments than strict enforcement.
They're "on the guestlist" but not on the list
Send them to the problem resolver. Check with whoever owns that allocation. Don't let door staff make guestlist calls. See guestlist management.
They have no ticket on their phone
Search the attendee list by name or email. Have a way to look up orders, because people delete emails, lose signal and run out of battery.
They're refused entry
Refusal decisions (intoxication, ID, behaviour) belong to the door supervisor and the venue. Make sure your refund policy covers refused entry, and that it's in your ticket terms.
Scan everyone, including guests and comps
If guestlist guests and comp tickets aren't checked in through the same system as paid tickets, your attendance figures will always be wrong. Scanning or ticking off everyone gives you:
- An accurate headcount for capacity and safety.
- The real no-show rate, which is often higher than people expect for free places.
- A single attendance record to use afterwards.
After the event: using check-in data
Check-in data tells you who actually came, which ticket sales alone can't. Use it to:
- Thank attendees with a post-event message and photos.
- Find no-shows. People who bought but didn't come might need a different approach next time.
- Identify regulars. Anyone who has checked in to several of your events is a prime candidate for first access. See how to get ticket buyers to come back.
- Understand arrival patterns. If check-in times show a late rush, you might adjust set times or the guestlist cut-off.
In Backline, door check-in records arrivals against each contact, so attendance becomes part of the history you can segment on.
Remember that attendance data is personal data. Use it in ways people would reasonably expect, keep it secure, and only send marketing to people who have agreed to receive it. See GDPR for promoters and artists.

Frequently asked questions
How do you speed up event check-in?
Plan for your peak arrival time, use more than one scanning device, and send a "know before you go" message so people arrive with tickets ready and ID out. A queue walker and a separate lane for problems stop slow cases from blocking everyone else.
What ID is accepted at UK club nights?
It depends on the venue's policy. Most accept photo ID that shows a date of birth and a holographic mark or ultraviolet feature, such as a passport, photocard driving licence or PASS-accredited proof of age card. Check with the venue and say what's accepted in your ticket information.
What should you do if a ticket has already been scanned?
Check when it was first scanned and whose name is on it. Follow the policy you set in advance, for example that the person whose ID matches the ticket name is admitted. Stay calm, because the person in front of you may have been sold a duplicate without knowing.
Should guestlist guests be checked in?
Yes. Checking in guests through the same system as paid tickets gives you an accurate headcount and shows you real no-show rates for free places. It also means guests become part of your attendance data for future events.
What can promoters do with check-in data?
Check-in data shows who actually attended, not just who bought. You can use it to thank attendees, spot regulars for first-access offers, follow up with no-shows and understand arrival times. Use it in ways people would expect, and only market to those who've agreed.
