## TL;DR
Reclaim unused permission set licenses or purchase more. The limit is enforced at assignment time, so over-assignment fails loudly.

## Error
```text
Salesforce permission set license exceeded: limit reached
```

## Steps
1. List assignments of the permission set license and find inactive users or users who no longer need it. Expected: reclaim candidates identified.
2. Remove the assignments you do not need. Expected: licenses freed.
3. If the demand is legitimate, purchase additional permission set licenses. Expected: the limit raised.
4. Retry the assignment. Expected: it succeeds.

## When to use
- Permission set license assignment fails on the limit
- A new team needs a permission set license that is maxed out
- The limit was fine until headcount grew

## When not to use
- The base user license is the problem (different limit)
- The assignment fails for another reason (read the error)
- You want to audit usage (same listing step, different goal)

## Tool compatibility
Salesforce permission set licenses, all editions.

### Variant phrasings
### limit hit by a managed package license
Managed packages consume their own license types. Check the package's license, not the org's.

### assignments exceed after a sandbox refresh
Sandboxes copy assignments; clean them up or ignore sandbox counts.

## Why it happens
Permission set licenses are separately purchased and separately limited. Teams treat them as unlimited until the assignment that crosses the line fails.
