I've had a wide range of responses from people calling me when I tell them I won't give personal details out based on a cold call.

A few understand immediately and are good about it. Most have absolutely no idea why I would even be bothered about an unexpected caller asking me for personal information. A few are practically hostile about it.

None, to date, have worked for a company that has a process established for safely establishing identity of the person they're calling. None. Lengthy on-hold queues, a different person with no context, or a process that can't be suspended and resumed so the person answering the phone has no idea why I got a call in the first place.

(Yet I'll frequently get email full of information that wouldn't be given out over the phone, unencrypted, unsigned, and without any verification that the person reading it is really me.)

The organisational change required here is with the callers rather than the callees, and since it's completely about protecting the consumer rather than the vendor, it's a change that's unlikely to happen without regulation.

What's fun here is, the moment they ask you for anything, flip the script and start to try to establish a trust identity for the caller.

Tell them you need to verify them, and then ask how they propose you do that.

Choose your own adventure from there.

Last time I did that, the caller said "but you can just trust that I'm from <X>." So I replied that they, likewise, could just trust that I'm me, and you could practically hear the light bulb click on. They did their best to help from there but their inbound lines aren't staffed effectively so my patience ran out before I reached an operator.


Credit card fraud departments are generally good about this.


I can't remember which company it was, but I got a call a few years ago about some issue with an account, and they wanted some information to "verify my identity"

I said wait a minute, you called me. Shouldn't I be verifying who you are?

The guy kind of laughed and said yeah, but this is the process I've been given to follow. I said I would call back on public customer service number and he said that would be fine.

It turned out it was a legit call, but just weird that they would operate that way.

I wish I could remember who it was. A credit card, I think.


This happened to me with AT&T herein Mexico: I have an AT&T pre-paid sim card that expires after a year. At the end of the year I got a call supposedly from someone form AT&T and told me about some special discount offer if I pre-paid for another year. The catch is that I needed to pay over there by phone ... (give my card details).

I told her that I preferred to call the AT&T number and for her to tell me what options should I press to get to her. She couldn't give me an answer to that.

Most likely a scam I guess.


Are they? Are they still asking about "mother's maiden name"?!


Anecdotally, I seem to have had the opposite experience. I've been doing this for at least 15 years, and never had a negative reaction. With bank, credit card, or finance-related companies, they seem to understand immediately. With other callers I've gotten awkward pauses, but ultimately they were politely accommodating or at least understanding that some issue would have to be processed through other channels or postponed.

However, I don't have strict requirements. When a simple callback to the support line on the card, bill, or invoice doesn't suffice--and more often than not it does, where any support agent can field the return call by pulling up the account notes--all I ask for at most is an extension or name that I can use when calling through a published number. I'll do all the leg work, and am actually a little more suspicious when given a specific number over the phone to then verify. Only in a few cases did I have to really dig deep into a website for a published number through which I could easily reach them. In most cases it suffices to call through a relatively well attested support number found in multiple pages or places[1].

I'm relatively confident that every American's Social Security number (not to mention DoB, home address, etc) exists in at least one black market database, so my only real practical concern is avoiding scammers who can't purchase the data at [black] market price, which means they're not very sophisticated. A callback to a published phone number for an otherwise trusted entity that I already do business with suffices, IMO. And if I'm not already doing business with them, or if they have no legitimate reason to know something, they're not getting anything, period.

[1] I may have even once used archive.org to verify I wasn't pulling the number off a recently hacked page, as it was particularly off the beaten path and a direct line to the department--two qualities that deserve heightened scrutiny by my estimation.


Someone needs to standardize a simple reverse-authentication system for this.

For example whenever a caller is requesting sensitive information, they give you a temporary extension directing to them or an equal, and ask you to call the organization's public number and enter that extension. Maybe just plug the number into their app if applicable to generate a direct call.

Like other comments have mentioned, the onus should be on them. Also, they would benefit from the resultant reduction in fraud. Maybe a case study on fraud reduction savings could help speed the adoption process without having to invoke the FCC.


In Sweden we have a special authetication system that is owned by the banks. It is called BankID and generally works well but it has flaws, especially that you shouldn't use it if they call you and ask to you do it since that is a security risk by itself.

It works if I call a bank or insurance company or something like that. A robot voice will ask me to authenticate and when I have done so and is transferred to an operator they will see that I authenticated. So it works when I call them but not the other way around. We need a new system.


I've had my cable company call me directly about an account issue and told them I couldn't validate it was them and the person got somewhat irate with my response, insisting there was no one I could call to verify them and that it has to be handled on that call. Turns out it was just a sales call (up selling a product) - which probably speaks to the level of talent they hire for that.
