A2P 10DLC Campaign Vetting Delays: Twilio cannot approve 10DLC Campaigns ourselves, and must rely on third parties who control our connections to carriers to sign off. These external processes are creating several week delays for our customers. We continue to escalate these issues and are working to reduce delays wherever possible. Further details will be shared in the Campaign Vetting Changes article as they become available.

US and Canada Termination Zones for Elastic SIP Trunking

What is a zone?

Elastic SIP Trunking calls to US and Canadian destinations are billed by zone. Each zone represents a collection of area codes and prefixes (NPA-NXX) where we charge the same rate. By segmenting destinations into zones, we are able to offer more competitive rates for each zone.

How do I tell which zone my call will fall under?

The vast majority of calls should fall into Zone 1. Well over 90% of Twilio’s overall calls are Zone 1. A specific list of prefixes and zones is available in the downloadable CSV rate deck at https://www.twilio.com/pricing/csv/sip-trunking-termination.
