WHERE IT WORKS
WHAT YOU GET
Choose and register your number (e.g., 10DLC in the U.S.), assign it with the Sinch Numbers API, then start two-way messaging and voice with customers on the same trusted number.
10DLC is a term for a traditional A2P phone number but speaks to the regulations and registrations that are required for messaging in North America. Toll-free numbers let customers call or text businesses free of charge, and short codes are memorable five-to-six-digit numbers that are ideal for very high-volume messaging campaigns.
Carriers require registration to verify your identity and use case in North America in particular, which is where 10DLC guidelines come in. Completing the brand and campaign registration process via The Campaign Registry (TCR) protects consumers from spam and preserves high deliverability for legitimate messages.
Timing depends on your number type and jurisdiction. Once registration and verification steps are complete, approval is typically quick and you can start sending messages.
An active Sinch account and API access are required to use mobile business phone numbers. You need to complete any required registration or verification steps before traffic can be sent.
Yes. Mobile business phone numbers are voice‑ and messaging‑ready, giving customers a consistent, unified channel.
Select from our global inventory—10DLC, local, toll-free, or short code—based on volume, geography, and customer preference. Our experts can guide your decision.
