How to complete business SMS registration (A2P 10DLC)

Before you can send SMS in Covent, your business must complete A2P 10DLC registration. Carriers require this to verify who is sending messages and to reduce spam.

Start from Settings > Communications > Business SMS Registration. You will need your IRS EIN letter — the document that confirms your Employer Identification Number, such as a CP575 notice or 147C letter. Upload as PDF, PNG, or JPG (up to 10MB).

Covent reads the document automatically. If any field cannot be extracted, you will be asked to confirm your legal business name, EIN, address, and IRS notice date before submitting.

Businesses created less than 30 days ago may be blocked by carriers until they are old enough to qualify.

There are two fees, passed through from carriers with no Covent markup:

• $30 one-time at submission — covers brand registration, campaign vetting, and carrier onboarding. Non-refundable once registration begins.
• $15 per month once approved — covers ongoing campaign and number fees while SMS stays active.

Per-message usage (SMS, calls, email) is billed separately at pay-as-you-go rates.

Carrier review takes 10-15 business days for legal-entity submissions. Sole-proprietor submissions have one extra step: you should receive a carrier verification text within 24 hours. Reply within 24 hours of receiving it so review can continue. Covent shows the status in the app and emails you if more information is required. Common rejection reasons: the EIN letter was unclear or incorrect, the business is too new, or your campaign is missing required opt-in and STOP/HELP language.
