ARIN’s Email Template Processor has been Retired

Posted: Monday, 03 June 2024

As first announced on 11 January 2024, on Monday, 3 June, ARIN retired the email template processor used to report reassignments. As of today, ARIN will no longer accept or respond to these email templates.

We encourage users to explore ARIN’s Reg-RWS service, which is a secure and efficient means of interacting with ARIN’s database. Visit to view our free “Reg-RWS Basics: Automate Management of ARIN Records with API” webinar to get started.

Organizations that do not need to automate reallocation and/or reassignment submissions may find it convenient to use ARIN Online to report this information.

For organizations that are unable to utilize Reg-RWS or ARIN Online, or for those that prefer to continue composing reassignment information in email templates, ARIN has provided an open-source template processor that customers may run within their network. To learn more, please visit

If you have questions about this transition or need assistance using Reg-RWS, please contact us by submitting an Ask ARIN ticket, chatting with us using ARIN Online, or calling the Registration Services Help Desk at +1.703.227.0660 (Monday-Friday, 7:00 AM – 7:00 PM ET).
