This appears to have once been a number Experian used to help customers, but it's no longer offering consumers any assistance. Instead, it appears to have switched over to a private line within Experian or have otherwise been changed to an Experian number that doesn't offer anything to consumers.
When I called this number, I got an automated message saying if I wanted assistance, I could either go onto Experian's website or could call 1-888-397-3742. To find out about Experian's products, the system recommended visiting the website, while suggesting the phone number for help with my personal credit report or score. The system then hung up automatically, giving me no way to further interact with this number.
A check of this number reveals that Experian apparently is not advertising it for anything, and it appears that the building where Experian was previously housed, and has since been sold off to other interests. This number apparently used to serve as the main point of contact for Experian's Illinois offices, which were located in Schaumburg. However, Experian sold their Schaumburg offices in 2023, and it appears that this number is one of the few things remaining from the completion of that sale.
Experian itself no longer lists this number anywhere on its site. It can still be found and its connection to Experian discovered, but only if the person asking is highly determined in their search. You can't use this number for any purposes; you've simply wasted your time unless you're trying to get the contact information for Experian.
To its credit, this phone number does offset one of the single biggest problems that customers face when calling a company: not leaving a phone number or other contact information to get to the new area for contact. It might be a waste of time for consumers, but it does show how quickly people can go through information and how what you might have done once to solve a concern might not work the same way.
But that's not enough to recommend using this number. Anyone dialing it might find value in getting the new number or a specific online address that saves them time once they've written it down. Otherwise, there isn't any benefit to attempting to use this number. The average person wouldn't even have used it for any purpose before the change of the Experian organization; now it's completely unhelpful for anyone at all.
