Frequently Asked Questions
What is A2P 10DLC and why does it exist?
A2P 10DLC is a US system that allows businesses to send Application-to-Person (A2P) messages via standard 10-digit long code phone numbers. Carriers introduced it to protect consumers from unwanted spam while giving businesses a sanctioned, higher-throughput channel for SMS and MMS messaging.
Who is an A2P consultation for?
Any developer or team building an application that sends SMS to US numbers. Whether you use Pingram or another platform, our experts can help you understand requirements and avoid common pitfalls.
How long does registration take?
Without Pingram: 1–4 weeks, depending on rejections and resubmissions. With Pingram: start testing immediately and complete registration in less than 3 days.
Do I need business registration? Where?
Yes, you need a registered business with a valid EIN (US), Tax ID (Canada), or equivalent in your country. Your business registration must match public records (address, name, etc.) that reviewers can find and verify.
Do I need A2P 10DLC for testing or internal use cases?
Yes, but Pingram provides a flexible sandbox for testing so your developers can start immediately while we register your A2P 10DLC.
Do I need separate registration for tenants (e.g., restaurants, merchants)?
It depends on the consent mechanism. Pingram can help with multi-tenant A2P 10DLC registration. Book a consultation to discuss your specific use case.
