# CreateUser
Creates a new IAM user for your AWS account.
For information about quotas for the number of IAM users you can create, see [IAM and AWS STS quotas](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_iam-quotas.html) in the *IAM User Guide*.
## Request Parameters
For information about the parameters that are common to all actions, see [Common Parameters](CommonParameters.md).
** Path **
The path for the user name. For more information about paths, see [IAM identifiers](https://docs.aws.amazon.com/IAM/latest/UserGuide/Using_Identifiers.html) in the *IAM User Guide*.
This parameter is optional. If it is not included, it defaults to a slash (/).
This parameter allows (through its [regex pattern](http://wikipedia.org/wiki/regex)) a string of characters consisting of either a forward slash (/) by itself or a string that must begin and end with forward slashes. In addition, it can contain any ASCII character from the \$1 (`\u0021`) through the DEL character (`\u007F`), including most punctuation characters, digits, and upper and lowercased letters.
Type: String
Length Constraints: Minimum length of 1. Maximum length of 512.
Pattern: `(\u002F)|(\u002F[\u0021-\u007E]+\u002F)`
Required: No
** PermissionsBoundary **
The ARN of the managed policy that is used to set the permissions boundary for the user.
A permissions boundary policy defines the maximum permissions that identity-based policies can grant to an entity, but does not grant permissions. Permissions boundaries do not define the maximum permissions that a resource-based policy can grant to an entity. To learn more, see [Permissions boundaries for IAM entities](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_boundaries.html) in the *IAM User Guide*.
For more information about policy types, see [Policy types ](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html#access_policy-types) in the *IAM User Guide*.
Type: String
Length Constraints: Minimum length of 20. Maximum length of 2048.
Required: No
**Tags.member.N**
A list of tags that you want to attach to the new user. Each tag consists of a key name and an associated value. For more information about tagging, see [Tagging IAM resources](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_tags.html) in the *IAM User Guide*.
If any one of the tags is invalid or if you exceed the allowed maximum number of tags, then the entire request fails and the resource is not created.
Type: Array of [Tag](API_Tag.md) objects
Array Members: Maximum number of 50 items.
Required: No
** UserName **
The name of the user to create.
IAM user, group, role, and policy names must be unique within the account. Names are not distinguished by case. For example, you cannot create resources named both "MyResource" and "myresource".
Type: String
Length Constraints: Minimum length of 1. Maximum length of 64.
Pattern: `[\w+=,.@-]+`
Required: Yes
## Response Elements
The following element is returned by the service.
** User **
A structure with details about the new IAM user.
Type: [User](API_User.md) object
