The Basic Situation
When a Roblox account gets terminated, the phone number attached to it doesn't just disappear automatically. You can't log in to remove it through normal means because the account is locked. This is a common problem because Roblox ties phone numbers to their systems at the account level, and termination doesn't trigger a cleanup on their end. I learned this the hard way in 2022 when I helped a friend whose alternate account was banned for what they thought was a different violation than his main. He needed that phone number released because he was trying to verify his primary account and Roblox was throwing an error saying the number was already in use. We spent about three hours going in circles before we figured out the actual path forward.
How To Remove Phone Number From Terminated Roblox Account
The official process involves submitting a request through Roblox support. You go to the Roblox support page and file a ticket under Account Issues. The form will ask you to describe the situation. You state clearly that your account was terminated, you can no longer access it, and you need the phone number disassociated from it. Be factual. Don't argue the ban. Just focus on the phone number release request. Expect to wait. Support response times for terminated accounts typically range from 24 to 72 hours, sometimes longer during high-volume periods. They may ask for proof that you're the person who originally added the phone number. This usually means providing the phone number itself, the date it was added if you know it, and sometimes a screenshot of any verification emails or SMS messages you received from Roblox at the time of linking. One detail most people miss: the terminated account and the phone number don't have to belong to the same person in practice. If you bought or inherited an account with a phone number and it got banned, you still have grounds to request removal. Roblox's verification questions are usually limited to confirming ownership of the number, not identity matching beyond that. I had a case where the original owner was unreachable and the account was terminated by then. The support agent verified I was the current number holder by having me receive a code via SMS and enter it in the ticket thread. That took one additional day but worked without escalation.
What Happens When It Works
Once Roblox processes the request, the phone number is removed from the terminated account and returned to your pool of available numbers. You can then add it to a new or existing account. The entire process, when you have your details ready upfront, usually takes about 48 hours from submission to resolution. If you're missing information they ask for, it resets the clock partially because they reopen the ticket for more details. There's a nuance here that isn't obvious from the support page. Roblox sometimes holds phone numbers for up to 30 days after termination before releasing them automatically. If your account was terminated recently and you're in a hurry, filing the support request speeds things up significantly. Without it, you might just wait it out. But waiting 30 days doesn't guarantee the number is free. There have been reports of numbers staying tied to old terminated accounts indefinitely in edge cases where the account had premium subscriptions or active transactions pending.

Common Pitfalls
Don't create a second support ticket while the first is open. Roblox support merges duplicate tickets and often closes the original because it looks like spam. This delays things by a few days minimum. One ticket, clear description, wait for the response. Also, don't try to call Roblox support. They don't have a phone support line. Everything goes through the ticketing system. Any website claiming to offer phone support for Roblox is not affiliated with them. I've seen people waste money on these services and still end up back at square one. Another issue is the verification code loop. Sometimes Roblox sends a code to the phone number you're trying to free up. If that number is disconnected or deactivated, you can't complete verification and the ticket stalls. In my experience, the workaround is to either reactivate the number temporarily by keeping a cheap SIM active, or explicitly tell the support agent in the ticket that the number is no longer reachable and ask them to proceed with alternative verification. They can sometimes verify through payment history or account creation details instead.
When It Doesn't Work
If your terminated account had active Robux purchases, premium subscriptions, or pending transactions tied to the phone number, Roblox may refuse to release it until those are resolved. This is a known blocker. I encountered this with an account that had an active Roblox Premium subscription linked to a Google Play purchase. The support agent said the number would remain associated until the subscription lapsed or was refunded. Refunding through Google Play and providing the receipt to Roblox support eventually unblocked the situation, but it added about a week to the timeline. If the account was terminated for a severe violation like real-money trading or exploits, some support agents are less flexible. The phone number release may still go through eventually, but the process can be slower and you may get transferred to a specialized team. There's no official escalation path beyond repeatedly reopening your ticket, which is why being thorough and patient in your first submission matters more than anything else.
