# Unique IDs

Since RC 4, (tested under RC3.7.x) all the blocks generated by GutenBricks will have unique IDs. A unique ID is made of a combination of the Bricks Builder's original ID and a block ID generated when the user inserts a new block:

Example:

```
// Bricks Builder ID
brxe-8e9775

// GutenBricks ID with a block ID as a suffix to ensure uniqueness 
b-8e9775_ls8i5k7o 
```

Note: the prefix "brxe" is replaced with "b-" to reduce the length of ID.
