Step 1 of 4

Initial Screening

We need to determine whether A2P 10DLC registration applies to your business.

Do you operate in the United States?*

Yes, I operate in the US

🌐 No, I do not

ℹ️

A2P 10DLC registration is not required. This applies only to businesses sending SMS/MMS to US numbers via US carriers. No further action is needed.

Step 2 of 4

Tax ID Verification

Your Tax ID (EIN) determines your eligible registration path and available business types.

Do you have a US Tax ID (EIN — Employer Identification Number)?*

✅ Yes, I have an EIN

❌ No, I don't have one

💼

Because you have a Tax ID, you are registering as a legal business entity. Sole Proprietorship is not available for businesses with an EIN.

⚠️

Without a Tax ID/EIN, your registration is limited to a Sole Proprietorship. If you have 2+ employees or an EIN, you must register as a legal business entity.
