I have been facing the following problem/issue for some time, but don't yet have a solution. Of the face of it, it's a relatively trivial issue. And maybe I'm making it more complicated or difficult than it needs to be.

I have a Capital One US bank account. But I can't log into online banking, even though I have a valid password, because I don't have a working US mobile phone. A variety of things can trigger two factor authentication with Capital One. And Capital One doesn't let one do two factor authentication using email, only SMS to a US mobile phone. And apparently it's quite fussy what it considers a valid US phone number.

I was wondering if anyone here had had that problem, and if so, were able to resolve it? A regular US number is quite an expensive thing to maintain outside the US, and even within the US. It seems especially expensive if all one needs it for is for an occasional SMS. There are a large variety of VOIP and virtual phone services available, some of which might work, but it's hard to know without trying them. And perhaps unsurprisingly, the Capital One reps I've spoken to have been completely uninterested in helping me find a solution.

I've had conflicting reports that Google Voice will work with Capital One, but I haven't tried that yet. Setting up Google Voice has two problems. One, relatively major, one relatively minor. The major one is that Google Voice requires a US number, so it's a bit of a Catch 22. Though it's possible it's less fussy about what it considers to be a valid phone number than Capital One is. The minor one is that Google Voice needs to think I'm in the US. Apparently the way around that is to use a VPN.

    If I were you I would encourage Capital One to change its policies by closing my account.

  • @phoog Thank you for your comment. That's certainly an option, and one I'm looking into. But it's not clear if I can transfer my funds to another bank without having access to my Capital One account in the first place. Mar 20, 2020 at 6:28
  • Well in the old days you could close an account by sending a signed letter in the mail. I don't suppose that had changed.

  • @phoog I'd also need to instruct the bank what to do with the money. I suspect they are going to need something more than a signed letter to transfer it to another bank account. Mar 20, 2020 at 7:06
  • The last (only) time I did it, they sent me a cashier's check. That was probably 40 years ago.

I want to report that I have solved my issue. Here is what I did. The following information is correct as of March 2020, except the part about T-Mobile which was current in fall 2019.

First, some background.

I had previously validated myself with Capital One. So I had a working password, but I could not log in, because when I tried to log in, the Capital One site would ask me for a US phone number to send a verification code, or make a verification call to. And I had no such number. A regular US phone number is a very expensive solution if one is outside the US, and only needs a phone number to receive an occasional SMS. And many US phone carriers don't allow international service of the kind required, anyway. And if they do, they probably don't do so at a reasonable cost.

T-Mobile is probably one of the few that does. I spoke to a USA T-Mobile rep last fall (fall 2019) from T-Mobile, who said this was the cheapest plan that would allow me to receive SMSs outside the USA: "T-Mobile : Unlimited calling and texting T-Mobile plan USD 20 / month. Calling is US domestic only. Texting is unlimited international." However, this information will clearly date quickly, and may already be out of date.

The other option was a VOIP/internet phone number. However, US banks (including Capital One) like to use SMS short codes to send SMSs to customers. So a requirement for such a number is that it should support receiving SMSs via short codes.

After some checking, anveo.com was one of the few VOIP/internet phone services which supported short codes. And there were also scattered reports of people using Anveo with success to do 2FA with US banks including Capital One. However, there were mixed reports about its customer service quality.

So I purchased a phone number from Anveo. Their system is that you have to pay in advance to obtain a credit, and then the amount is deducted from your credit. To set up a new mobile phone number, as of March 2020, there is a one-time cost of USD 10, and after that it costs USD 2 per month for the basic plan, which supports receiving SMSs (USD 0.01 per incoming SMS). Their system wasn't particularly smooth. First, I could only purchase a block of credit, with a minimum of USD 15, and then USD 25, 50, 75, in jumps of 25. And I could only purchase it via Paypal. I talked to a customer service rep, and he said there was no option other than Paypal, and I could not charge it over the phone. Then Paypal had a problem with me trying to use a US credit card in India, so I finally had to use a VPN to make it look like I was in the US. And then Anveo asked me to verify that I had made the payment by sending them a photo of my ID, as well as a video of myself holding the ID and saying that I authorized the payment. I used my passport. I appreciate that all these security checks may have been a good idea, but it did feel a bit like running a gauntlet.

Note that there are a lot of other providers, including free ones. And it's possible that others would work. But I went with the one that seemed the most likely to work. If you already have a Google Voice number, that may be a good bet, though I'm not sure what the current Google Voice support for short codes is like.

Furthermore, when I tried to use the new phone number to log in, I could not initially do so. When I tried to log in with my password, it asked me for a phone number to send an SMS or make a call too. When I added my new number, it rejected it. So I had to contact Capital One customer support.

Because I wasn't able to log into my account, I had to go through another session of verification with Capital One before they would add the new phone number. But once I added it, I was able to use it to log into my account.


Another alternative to the previous answer.

I have personally used the Hushed app (internet phone number) with both Bank of America and American Express without any issues. I previously used it with Chase but it stopped working at some point in 2020.

It costs US$4.99/month with unlimited text/calls and it is accessible from multiple devices and even from a Slack channel. It can be paid through GooglePay and ApplePay so the whole credit card/location issue is avoided.

If you renew it promptly you keep the number you chose when registering, which can be from any area code of your choice. A friend of mine was even able to port their T-Mobile number to Hushed but it required a lot of back and forth with support of both Hushed and T-Mobile.

Hope it helps!
