As part of our commitment to improving service performance and reliability, we are announcing an important update to our Deactivation File Service.
To ensure your service continues without interruption, it is essential that you update your systems to use the new endpoint before the change date.
Summary of Changes We are decommissioning the FQDNs listed below and replacing them with a new, unified endpoint. This update also includes several enhancements to the service.
To be Terminated: ftp01.sinch.com ftp01.clxnetworks.com
Replacement Endpoint: deact.prod.sinch.com IP Address: 184.169.203.194
Start Time
2026-06-15 15:00
Service Enhancements The new endpoint introduces the following improvements:
Directory Structure: The Sprint directory has been removed, and a new Tier_2 directory has been added to house deactivation files from our tier 2 carrier connections. File Naming Convention: The date in the file name will now reflect the day the service is run (e.g., deactivation_20250205.txt), rather than the previous day. Expanded Data: Deactivation data from Verizon is now available through the new endpoint.
We recommend making these changes at your earliest convenience to ensure a seamless transition. Please let us know if you have any questions. Posted on
