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.

Before you begin

• Review Long-code Sender IDs 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 and Supported feature filters.

• Create a business identity and address before you begin, or create them during Step 2: Enter general details. See Manage identities and addresses.

• Review Compliance content requirements 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.

3. Review the Pricing and Identity Requirements.

4. Select an existing business Identity and Address, or create them during this step.

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.

Step 3: Select Sender IDs

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.
