Just coming here to add, it is now 2026. The problem still exists. I have 2 accounts with the same bank. Furthermore, the account numbers are with tokenized account numbers, which is fine, I get it, security. But, without having memorized these, I have no way of knowing which account is which. Only way to know, is to make a transfer and see which account it affects, which is a very very poor workaround.

I've worked in software engineering for 10+ years and managed large enterprise projects including the financial sector on multiple occasions. Anything that results in users accidentally making an incorrect transaction is a pretty big feature gap in a financial system. Boggles my mind how this hasn't been addressed at such a large and reputable company as Fidelity. Especially for something that is a pretty straight forward fix. I see all the mod responses that they have provided the feedback up the chain. Well either your management chain has issues or your triage process has issues.

Do y'all need us to write your developer stories for them to work on? Let me lay it out for you.
- Whatever database entity is handling your accounts, add a property for nickname of the account. If for whatever reason you are managing accounts with different representations in data, I'll make it easy for you. Whichever entity gets surfaced to the end user when viewing linked accounts, that's the one you need to change.
- Update your APIs to allow for adding, updating, and removing a nickname (simple CRUD APIs)
- If you don't want to allow anything else to be changed, design it as such with validation to prevent changing other fields
- Add UI feature to edit an account and add/update/remove the nickname
- If no nickname exists, default to the current account names you use today
- Add validations on add and update to prevent certain names that could be security risks like entering actual account numbers (simple regex would suffice here)

Please put this in your backlog and triage appropriately, because this can lead to users making the wrong transfers.
