Choose a case-sensitive Nano ID
Generate a different identifier format and understand why short IDs and letter case need care.
For operators
Generate a different identifier format and understand why short IDs and letter case need care. This is isolated practice with invented records. Nothing is uploaded or written into a live system.
Read these instructions on any device. Watch or practise a chapter on a desktop or laptop, with a desktop or mobile application layout. Demonstrations use sample data and simulated scanners.
Choose a case-sensitive Nano ID
- Choose a Nano ID
Choose a Nano ID.
Nano ID and ULID are different formats from UUID. Nano ID is case-sensitive; changing its case changes the identifier.
- Choose two short identifiers
Choose two short identifiers.
Use the default length of 21 characters. Reducing the length increases the chance of a collision.
- Generate Nano ID values
Generate Nano ID values.
These identifiers are not compact UUIDs. Preserve every character, including its case, when copying them to another system.
Review the result and its limits before using it in another application.
