# United Kingdom sender ID registration process in AWS End User Messaging SMS
United Kingdom sender ID registration

**Note**  
With our updated console experience you are now seeing a registration **Name** field for your registration. This field is set to "–" as we do not manually backfill any of your service values to prevent interruption to your service and let you maintain your security posture. A registration **Name** is an optional friendly name field that can be updated using the tags on the registration details page. For more information on how to add a **Name** tag, see [Change a registration's name in AWS End User Messaging SMS](registrations-friendly-name.md).

The United Kingdom's (UK) Mobile Ecosystem Forum (MEF) SMS Sender ID Protection Registry was established to facilitate the identification and blocking of fraudulent SMS messages, protecting consumers as well as legitimate businesses and organizations. The registry enables organizations to register the Sender IDs used when sending SMS to customers in the UK, limiting the ability of fraudsters to impersonate a brand.

If you have protected your Sender ID with MEF you are required to register your Sender ID through AWS End User Messaging SMS. 

**Important**  
If your Sender ID is protected by MEF then a completed Letter of Authorization (LOA) is required. The information provided must be of the end company. If you are registering on behalf of a company they are required to authorize AWS and the LOA should not include or reference your company information.  
Download the template for the [LOA](samples/AWS_Protected_Sender_ID_Letter-of-Authorisation_UK.zip).
Clearly specify the sender ID requested and have other details such as website and sample message templates filled in correctly with no missing details. The casing of the Sender ID must match what is registered with MEF.   
Complete all highlighted fields.
The LOA must be dated within the last 30 days.
Create a PDF of the LOA to upload as part of completing the **Sender ID info** section of your [UK registration](registrations-uk-form.md#registrations-uk-form.title). The maximum file size is 400 KB.
Complete the [UK sender ID registration form](registrations-uk-form.md#registrations-uk-form.title) and omit the **Letter of authorization image – optional** field.
