What is carrier registration?
Carrier registration, also known as A2P 10DLC, refers to a standard in the United States that allows businesses to send Application-to-Person (A2P) type messaging via standard 10-digit long code(10DLC) phone numbers. Major US carriers consider all messages sent using virtual phone numbers with local area codes, like the ones provided by Quo to be A2P.Who is required to register?
Every Quo customer, as virtual phone users who send texts to any US number needs to register. This applies to using Quo for both business and personal use (i.e., texting friends and family). We’re unable to support a personal use case exemption at this time.How long does registration take?
Processing times can vary. Most approvals happen within 24-48 hours; others have remained in pending status for up to 20 days. In rare cases where key information is unable to be verified, registration may take longer than 30 days. You’re not able to message US numbers while waiting for your registration approval.If my registration is rejected, what can I do?
Review the reason your application was rejected in-app and in a related email, make the required changes and resubmit your application. Because a third-party company handles your information verification, the information we receive is limited, and Quo does not have any control over whether your application is approved or rejected.Registration best practices
Provide accurate information to help avoid a delay or rejection.- Match tax documents exactly: Use IRS Form CP-575 for US businesses
- Use consistent branding: Ensure business name, website, and samples align in use of your business name
- Ensure your addresses are complete: Include all address components (suite, apartment numbers, etc.)
Overview
US carrier registration (also referred to as A2P 10DLC) is required for all businesses sending text messages to US phone numbers through Quo. This registration improves message deliverability and prevents carrier filtering by verifying your business and messaging use case.Prefer a walkthrough?
