# ModifyIdFormat


Modifies the ID format for the specified resource on a per-Region basis. You can specify that resources should receive longer IDs (17-character IDs) when they are created.

This request can only be used to modify longer ID settings for resource types that are within the opt-in period. Resources currently in their opt-in period include: `bundle` \$1 `conversion-task` \$1 `customer-gateway` \$1 `dhcp-options` \$1 `elastic-ip-allocation` \$1 `elastic-ip-association` \$1 `export-task` \$1 `flow-log` \$1 `image` \$1 `import-task` \$1 `internet-gateway` \$1 `network-acl` \$1 `network-acl-association` \$1 `network-interface` \$1 `network-interface-attachment` \$1 `prefix-list` \$1 `route-table` \$1 `route-table-association` \$1 `security-group` \$1 `subnet` \$1 `subnet-cidr-block-association` \$1 `vpc` \$1 `vpc-cidr-block-association` \$1 `vpc-endpoint` \$1 `vpc-peering-connection` \$1 `vpn-connection` \$1 `vpn-gateway`.

This setting applies to the IAM user who makes the request; it does not apply to the entire AWS account. By default, an IAM user defaults to the same settings as the root user. If you're using this action as the root user, then these settings apply to the entire account, unless an IAM user explicitly overrides these settings for themselves. For more information, see [Resource IDs](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/resource-ids.html) in the *Amazon Elastic Compute Cloud User Guide*.

Resources created with longer IDs are visible to all IAM roles and users, regardless of these settings and provided that they have permission to use the relevant `Describe` command for the resource type.

## Request Parameters


The following parameters are for this specific action. For more information about required and optional parameters that are common to all actions, see [Common Query Parameters](CommonParameters.md).

 **Resource**   
The type of resource: `bundle` \$1 `conversion-task` \$1 `customer-gateway` \$1 `dhcp-options` \$1 `elastic-ip-allocation` \$1 `elastic-ip-association` \$1 `export-task` \$1 `flow-log` \$1 `image` \$1 `import-task` \$1 `internet-gateway` \$1 `network-acl` \$1 `network-acl-association` \$1 `network-interface` \$1 `network-interface-attachment` \$1 `prefix-list` \$1 `route-table` \$1 `route-table-association` \$1 `security-group` \$1 `subnet` \$1 `subnet-cidr-block-association` \$1 `vpc` \$1 `vpc-cidr-block-association` \$1 `vpc-endpoint` \$1 `vpc-peering-connection` \$1 `vpn-connection` \$1 `vpn-gateway`.  
Alternatively, use the `all-current` option to include all resource types that are currently within their opt-in period for longer IDs.  
Type: String  
Required: Yes

 **UseLongIds**   
Indicate whether the resource should use longer IDs (17-character IDs).  
Type: Boolean  
Required: Yes

## Response Elements

Type: Boolean

## Errors


For information about the errors that are common to all actions, see [Common client error codes](errors-overview.md#CommonErrors).

## Examples


### Example


This example sets the UseLongIds parameter to true for instances, so that instances you launch receive longer IDs. 

#### Sample Request


```
https://ec2.amazonaws.com/?Action=ModifyIdFormat

&UseLongIds=true
&AUTHPARAMS
```

#### Sample Response
