Just redeemed for UA and IB. On both, inside 5 minutes, both times I was asked for code that they have sent to my mobile... really annoying. Is this really necessary, twice inside five minutes?

I think they request it exactly if you redeem too often. On the account where I redeem once a month they requested it once in the beginning and no more.

Might be. I also redeemed 3 days before that with BA, and no code was requested. Too often is apparently more than one redeem per week.

I was asked last year and it was super annoying. I don't have a US cell number so it didn't work. Mr.'s account was frozen because I used those virtual text services and they said they will re-open it when he has a US cell number. I think it's reasonable to send a code to the email address provided but a US cell phone number is too much.

Well, they want to make sure you fit the profile - if they interview people in the US, and when you say you live in the US they want to make sure you are from the US.
It can be a fixed number, no need to be a cell number.

Well, that is all-righty. But, if they check my ATT mobile, and when I redeem again in 3 minutes, they have urgent need to check that same number again, this is useful for what? Have they all the sudden lost my mobile number (that they have checked just minutes ago) or think I have just been beamed to Indonesia? The only reason I can see is that they are trying to obstruct and annoy people from cashing in their legally earned dollars. Which is stupid, when you are getting 20+ surveys per day...

What if you moved out of the US and haven't used your points?

They know where you are- location of the server is a pretty good indicator. When traveling outside of the US I've gotten messages that I can't access a particular survey because I"m not in the US. (It's not perfect- I once had issues getting into a Fidelity account when in India and when I called they asked if I'd been in HK. I hadn't, but my employer had servers in HK.)

It's just another grab for information. It's one of the reasons I keep a landline as the equivalent of a spamcatcher e-mail address.

It may be lazy IT - they couldn't be bothered to write a timestamp or update a timestamp from the last time asked.

Help. Privacy. Quote: "Please note, if you redeem more than one reward within 7 days, you may be asked to verify each transaction".

Well, you can fool them with a proxy server and pretend you are in a specific country (just like your example with HK, but deliberate). You can even use a site that receives SMS for free (if nobody has used it before, as the celular number must be unique).

Hertz
 

I've redeemed Hertz rewards "a zillion times" over the years. I've submitted twice for Hertz rewards recently, and each time after about a week, my e-reward points are returned to my account with the notation that the redemption "failed". Nothing has changed re my Hertz account, recently, versus over the years. I'm using the same Hertz number, same address, same name.

Anyone else experience similar re Hertz, recently?

Tried the free SMS thing and it didn't work.

No longer getting surveys
 

Hi All! I’m new to the forum but have been doing e-rewards surveys for awhile now. I go in spurts but recently have had a ton of downtime and were traveling soon so I ramped up the amount of surveys I take. Not sure if that triggered something, but I haven’t received any surveys in over a week now. I’ve checked email and logged into the website.

Anyone else experienced this recently or just me?

My husband also decided he’d do surveys so I signed him up a few days ago and he hasn’t received anything either.

Nope, just did one last week for 1100 Gold Points, and all I had to do is enter the code that was texted to my US cell number. Points posted within 72 hours. You might need to email them.
