Frequently Asked Questions
Everything you need to know about A2P 10DLC compliance.
What is A2P 10DLC?
A2P (Application-to-Person) 10DLC (10-Digit Long Code) is a carrier-mandated registration system for businesses sending SMS messages to US and Canadian recipients. It ensures legitimate business messaging and prevents spam. [citation:6]
Do I need A2P 10DLC registration?
Yes, if you send SMS messages from a US or Canadian phone number to recipients in the US or Canada through an application. All messaging traffic must comply with A2P/10DLC carrier policies. [citation:1]
What are the registration requirements?
You need to register your Brand (business identity) and your Campaign (message use case). This includes providing business information, a valid website, privacy policy, Terms & Conditions, and opt-in consent documentation. [citation:7]
What happens if I don't comply?
Non-compliant messages may be filtered, blocked, or subject to non-compliance fees. T-Mobile imposes fines of $500-$2,000 for different categories of violations. [citation:5]
What is the opt-in requirement?
You must obtain explicit consent from recipients before sending messages. Your privacy policy and opt-in flow must be clearly visible on your website, especially near phone number collection forms. [citation:4]
What should my messages include?
Every first message must identify you as the sender, include opt-out language (e.g., 'Reply STOP to unsubscribe'), and clearly explain why you're contacting the recipient. [citation:5]
Can I send marketing messages?
Yes, but you must have explicit consent, include opt-out instructions, and maintain a compliant privacy policy that does not share or sell user data. [citation:4]
How long does registration take?
Brand registration typically takes 1-3 business days. Campaign registration can take 3-7 business days depending on carrier review. [citation:6]
