Toll-free verification API and Console now in Public Beta
Twilio’s self-service Toll-Free verification tooling is now in Public Beta. Customers who are looking to submit toll-free phone numbers for verification can now do so directly within Messaging Compliance API or Twilio Console without going through Support or Sales.
With Toll-Free verification tooling, you can:
- Submit a new US or Canadian toll-free phone number for verification
- Utilize customer profiles for a Toll-Free verification that were created in other compliance programs like A2P 10DLC, STIR/SHAKEN, etc
- Get a list of toll-free verification records, including status and rejection reason (if rejected). Historical verifications submitted manually through CSV process are available for most toll-free numbers.
- Re-submit a rejected verification (if rejection type is allowed to resubmit)
- Subscribe to Event Stream’s webhook for toll-free verification events

WhatsApp inbound messages will now include reply context
When users reply to a specific WhatsApp message, Twilio now passes additional context to the WhatsApp Sender’s webhook URL. The OriginalRepliedMessageSender and OriginalRepliedMessageSid parameters will include information about the previous message the user replied to. If you need the content of the original message, you can use this API to fetch the Message Resource.
Note that only message replies to messages sent within the last 7 days will contain this additional context. Incoming message replies to messages sent over 7 days ago will still be delivered, but will lack this additional information.
For more information about this and other inbound message parameters, please refer to this page.

Programmable SMS Geo Permissions - Israel and Palestine Prefix Update
Twilio is making changes to Geo-Permissions in the Twilio Console to better differentiate traffic being sent to both Israel and Palestine. Palestine, which previously was only +970 will now include Palestinian networks operating with +972 prefixes. If you enabled geo permissions for Israel and/or Palestine, then we have updated your selection based on the corrected prefixes. Israel will no longer send traffic to +97256 and +97259 since these two prefixes are associated with Palestinian Jawwal and Wataniya cellular communication company.
If needed, you can enable or disable SMS Geo Permissions to any country at any time in Twilio Console by following the steps in this Support Article.
