# Create a US 10DLC Verification

Follow these steps to submit US 10-digit long-code DID numbers for verification
before using them to send A2P SMS messages to US recipients.

Important

This guide applies only to Long-code Sender IDs used for messaging to US
recipients. For other supported destination countries, see
[Create a Long-code Sender ID Verification](create-long-code-verification.html).

## Before you begin

- Review [Long-code Sender IDs](../sender-id-verification-types/long-code.html) to confirm that Long-code is the
  correct Sender ID type for your messaging use case.
- Make sure your DIDWW account has an active US 10-digit long-code DID number
  that supports **Outbound A2P SMS**. See
  [Buy Numbers](../../../phone-numbers/buy-numbers/index.html) and
  [Supported feature filters](../../../phone-numbers/buy-numbers/filters-reference.html).
- Create a business identity and address before you begin, or create them
  during **Step 2: Enter general details**. See
  [Manage identities and addresses](../../../identities/getting-started.html).
- Review [Compliance content requirements](../compliance-content-requirements.html) before preparing your business,
  campaign, consent, and sample-message information.

## Step 1: Open the verification form

1. In the DIDWW User Panel, go to **SMS > Sender ID Verifications**.
2. Open the **Get Started** tab.
3. Find the **Long-code** Sender ID type and click **Create New**.

Alternatively, on the **Verifications** tab, open **Create New** and select the **Long-code** Sender ID type.

## Step 2: Enter general details

1. Enter a **Friendly name**.
2. Select **United States** as the **Target country**.
3. Review the **Pricing** and **Identity Requirements**.
4. Select an existing business **Identity** and **Address**, or create them during this step.
5. Click **Next**.

Important

A DID number can be linked to only one identity. If a number already uses
an identity for DID registration, Emergency Calling, or another service,
select the same business identity for the US 10DLC Verification.

If the number does not have an identity, you can use the business identity
selected during this step. Personal identities cannot be used for US 10DLC
Verification.

For field descriptions, see [Long-code verification setup
fields](../sender-id-verification-reference.html#long-code-verification-reference).

## Step 3: Select Sender IDs

1. Under **Available source numbers**, select the US DID numbers that you want to verify.
2. Move the numbers to **Allowed source addresses**.
3. Review the selected Sender IDs.
4. Click **Next**.

Note

You can include up to 49 Sender IDs in one verification.

Use the **DID number** and **Description** filters to narrow the list of
available numbers. To remove all numbers from **Allowed source
addresses**, click **Remove all**.

Only DID numbers that meet all the following requirements appear under
**Available source numbers**:

- The number is an active US 10-digit long-code DID number.
- It supports **Outbound A2P SMS**.
- It is not assigned to another Sender ID Verification.
- It has no assigned identity or uses the business identity selected in
  **Step 2: Enter general details**.

Numbers linked to a different business identity or a personal identity are not
available for selection.

If no numbers appear, check whether your existing numbers meet these
requirements. To purchase a new number, see
[Buy Numbers](../../../phone-numbers/buy-numbers/index.html).

   opt-in confirmation checkbox.

After submission, the verification is added to the **Verifications** tab on the **Sender ID Verifications** page. When
you open this page, the **Get
Started** tab is displayed by default. Open the **Verifications** tab to find the submitted verification and use its
