Carrier Registration

How A2P 10DLC brand and campaign registration works for SMS messaging through Leadping.

Before your business can send SMS through Leadping, carriers require A2P 10DLC registration. This is the U.S. carrier registration process for business messaging over 10-digit long-code numbers.

Leadping manages the submission process and carrier coordination, but approval ultimately belongs to the carriers.

What A2P 10DLC means

A2P means application-to-person messaging. 10DLC means 10-digit long code. Together, A2P 10DLC is the framework carriers use to identify business senders, understand message use cases, and apply traffic limits.

Without approved registration, SMS messages may be blocked or heavily filtered. Voice calling can usually begin before SMS approval is complete, subject to the rest of your account setup.

What Leadping handles

Leadping helps simplify the registration process by handling the operational work:

• Collecting required business and campaign details
• Preparing brand and campaign submissions
• Coordinating with carrier registration systems
• Reviewing message use cases for obvious carrier risk
• Updating your setup when approval status changes
• Connecting approved campaigns to production numbers

This keeps your team out of the carrier paperwork while still making sure the information submitted is accurate.

What you need to provide

Registration depends on accurate, verifiable business information. You may need to provide:

• Legal business name
• EIN or tax ID
• Business address
• Website
• Authorized contact information
• Message use case
• Sample message content
• Opt-in language and lead source details
• Expected traffic volume

The information must match public and official records. Inconsistent or misleading details are a common cause of delays or rejection.

The approval process

The typical process is:

1. Information collection: Leadping gathers the required business, campaign, and consent details.
2. Submission: Leadping submits the brand and campaign for carrier review.
3. Carrier vetting: Carriers and registration partners evaluate business legitimacy, use case, content, and risk.
4. Approval or remediation: If approved, SMS setup continues. If rejected or flagged, Leadping will identify what needs to be corrected where possible.
5. Number assignment: Approved campaigns are connected to numbers and prepared through TrustedSetup.

Timelines vary by carrier backlog, business type, and whether the registration details match verified records. Some approvals complete quickly; others require additional review.

Important limitations

Leadping cannot guarantee approval. Carriers make the final decision.

Carrier rejection is more likely when:

• Business information cannot be verified
• The use case is prohibited or high risk
• Consent language is missing or weak
• Sample messages do not match the stated campaign
• The business has prior spam, fraud, or abuse history
• The submission appears to use a shell company or inaccurate EIN

Severe fraud or repeated denials can prevent further submissions. In some cases, approval may require a different legal entity with clean, verifiable records.

How to improve approval odds

You can help the process move faster by providing complete, accurate information the first time.

Before submitting, make sure:

• Your legal name, EIN, address, and website are consistent
• Your website clearly represents the business
• Your consent language names the sender and contact method
• Your sample messages match the actual outreach
• Your use case does not fall into a prohibited content category
• Your lead sources can provide TrustedForm certificates

Leadping will guide the registration workflow, flag obvious issues, and connect approved campaigns into the broader outreach setup.
