What's changing?
Starting October 19, FHLMC will be migrating individual sellers to the new SSID, and we will notify you when that change is made for your firm. Until you receive your migration notification, please continue to use the old SSID.
We're going to keep the current SSID, 152360, active through the migration period. Please be ready to go as soon as possible, because After receiving the notification of a completed migration, you must begin using the new SSID. Rocket will no longer accept new deliveries under 152360 after you have received your migration notification. Any delivery submitted under the old SSID on or after that date will be rejected and will need to be resubmitted under 989703.

October 19th
What's changing?
Freddie Mac and Rocket Corr+ will begin individually migrating partners to the new SSID. If you are an approved PartnerClear user, you will receive a notification from us when this happens.
Once you receive that notification, begin delivering PartnerClear loans under SSID 989703.
What to do in LSA?
After you are migrated, when you set up ULDD deliveries for Rocket Corr+ Partner Clear:
- Select the appropriate aggregator.
- Choose the loans you want evaluated against the aggregator's terms of business.
- If available, in the Aggregator drop-down menu, select Rocket Corr+'s new SSID: 989703.
That's the only change to your workflow.
What's not changing?
Loans already in your pipeline under SSID 152360 stay active during the transition. There's nothing to redo on existing work. The change applies to new deliveries only.
Frequently asked questions
Here is a quick rundown of questions we've seen already. Have an unanswered question? Your Corr+ Account Executive can walk your team through the change before or after October 19.
Delivery teams run on predictability, and a change like this should never arrive as a surprise at month-end. The transition period gives your team time to make the update on a normal day, confirm the first delivery goes through cleanly, and move on. We'd rather you have more cushion than you need.
Share this page with whoever sets up ULDD deliveries in LSA for your organization, typically secondary marketing, post-closing or loan delivery. If it's helpful, your Rocket Corr+ Account Executive can send the instructions to them directly.
Your existing deliveries don't need to be changed. Beginning November 2, 2026, Rocket will no longer accept new deliveries under 152360. Any delivery submitted under the old SSID on or after that date will be rejected and will need to be resubmitted under 989703.
The change is part of Rocket's ongoing platform integration. We know these changes can impact your routine. That's why we're communicating now and getting ahead of the official retirement of the old SSID, 152360, on November 2, 2026.
