Sign Number Prefixes
Add an optional prefix to sign numbers for clearer identification.
Sign number prefixes let you add a consistent label to the beginning of every sign number in an event. This makes it easier to identify which event or zone a sign belongs to, especially when your organisation runs multiple events at the same time.
How prefixes work
You set a prefix string at the event level, and Signplanr prepends it to each sign's auto-generated number. For example, if you set the prefix to "A-", a sign numbered 042 displays as A-042 throughout the app, in exports, and on QR code labels.
Setting a prefix
- Open the event and go to Settings.
- Find the Sign Number Prefix field.
- Enter your prefix string (e.g. "A-", "FEST-", or "B2-").
- Click Save.
All existing and future signs in the event reflect the updated prefix immediately. Signs that carry the old prefix are renumbered: changing "A-" to "B-" turns A-042 into B-042, and clearing the field turns it back into 042. Signs whose numbers were entered by hand and don't start with the old prefix are left as they are.
Map pins
Pins on event maps show the number without the prefix, so "A-042" appears as 042 on the pin. The pin is deliberately small so dense maps stay readable, and the prefix is the same for every sign in the event. The full number still appears in the pin's detail card, in the Design view label tags, on QR labels and in every export.
Manual overrides
You can override the generated sign number on any individual sign. Open the sign detail page, edit the Sign Number field, and enter any value you like. Overridden numbers must still be unique within the event.
Keep prefixes short — two to four characters work best. Long prefixes make sign numbers harder to read on printed labels and mobile screens.
Uniqueness rules
Every sign number (prefix + number) must be unique within its event. Signplanr prevents you from saving a duplicate. If changing the prefix would give a sign the same number as a manually overridden one, the change is refused and nothing is renumbered. Edit the conflicting sign first, then change the prefix.
