# Create a Long-code Sender ID Verification

Follow these steps to submit eligible Long-code DID numbers for verification before using them to send A2P SMS messages.

Important

This guide applies to supported destination countries other than the United States. For messaging to US recipients, see
[Create a US 10DLC Verification](create-us-10dlc-verification.html).

## Before you begin

- Review [Long-code Sender IDs](../sender-id-verification-types/long-code.html) to confirm that this Sender ID type matches your messaging use case.
- Make sure your DIDWW account has an active DID number for each destination
  country. Each number must support **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 [A2P SMS compliance requirements](../compliance-content-requirements.html) before preparing sample messages or consent 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 the **Target countries**.

   > Note
   >
   > Do not select the United States. US Long-code Sender IDs require a [US 10DLC Verification](create-us-10dlc-verification.html).
3. Review the **Pricing** and **Identity Requirements** for the selected countries.
4. Select an existing business **Identity** and **Address**, or create them during this step.
5. Click **Next**.

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

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 Sender ID 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 Sender ID
Verification.

## Step 3: Select Sender IDs

1. Under **Available source numbers**, select the DID numbers 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 active.
- 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).

1. Enter the **Legal Company Name** and **Website**.
2. Select the **Use case type**.
3. Enter the **Campaign description**.
4. In **How will consumers opt in?**, explain how recipients agree to receive
   the messages.
5. Enter two representative messages in **Sample content message #1** and
   **Sample content message #2**.
6. Click **Next**.

## Step 5: Review summary and submit

1. Review the **Verification Details**, **Identity Details**, and **Sender IDs**. Use **Copy** or **Select All** to copy the listed Sender IDs.
2. Review the estimated verification time and charges under **Summary**.
3. Click **Submit**.

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
[status](../sender-id-verification-reference.html#sender-id-verification-statuses) to track the review.

The actual review time may vary depending on the selected countries and
whether additional information is required.

If the status changes to **Changes Required**, see
[Resubmit a Sender ID Verification](resubmit-sender-id-verification.html).
