# Bucket Naming Rules

The following bucket naming rules apply to general purpose buckets. Bucket names:

- Must be between three (min) and 63 (max) characters long.
- Can consist only of lowercase letters, numbers, periods (.), and hyphens (-).
- Must begin and end with a letter or number.

Bucket names must not:

- Contain two adjacent periods.
- Be formatted as an IP address (for example, 192.168.5.4).
- Start with the prefix xn--.
- Start with the prefix sthree-.
- Start with the prefix amzn-s3-demo-.
- End with the suffix -s3alias.
- End with the suffix --ol-s3.
- End with the suffix .mrap.
- End with the suffix --x-s3.

## Naming a Bucket

Before naming a bucket, you may want to review the following recommendations.

- Choose a bucket naming scheme that is unlikely to cause naming conflicts.
- Append globally unique identifiers (GUIDs) to bucket names.
- Avoid using periods (.) in bucket names.
- To ensure that you can reuse bucket names, do not delete buckets.
- After you delete a bucket, be aware that another Wasabi account in the same partition can use the same bucket name for a new bucket and potentially receive requests intended for the deleted bucket.
