# Generate Random UUIDs Without An Extension
|
|
|
|
In other posts I've covered how to generate v4 random UUIDs in PostgreSQL
|
|
[using the `uuid-ossp` extension](generate-a-uuid.md) as well as the more
|
|
up-to-date method of [using the `pgcrypto`
|
|
extension](generating-uuids-with-pgcrypto.md).
|
|
|
|
As of PostgreSQL v13, you no longer need to add an extension for v4 UUID
|
|
generation. It comes built-in as the `gen_random_uuid()` function.
|
|
|
|
```sql
|
|
> select gen_random_uuid();
|
|
gen_random_uuid
|
|

|
|
(1 row)
|
|
```
|
|
|
|
If you need other non-v4 UUID functions, you'll have to stick with
|
|
[uuid-ossp](https://www.postgresql.org/docs/current/uuid-ossp.html).
