# 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.
- Bucket names can consist only of lowercase letters, numbers, periods (.), and hyphens (-).
- Bucket names must begin and end with a letter or number.
- Bucket names must not contain two adjacent periods.
- Bucket names must not be formatted as an IP address (for example, 192.168.5.4).
- Bucket names must not start with the prefix xn--.
- Bucket names must not start with the prefix sthree-.
- Bucket names must not start with the prefix amzn-s3-demo-.
- Bucket names must not end with the suffix -s3alias.
- Bucket names must not end with the suffix --ol-s3.
- Bucket names must not end with the suffix .mrap.
- Bucket names must not 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.
