If someone calls you from this number it could very well be a scam as they have spoofed an American Express fraud line. Ringing to this number yourself, however, will be legitimate.

Caller: AMEX frrom Fraud Team

Definitely not a scam. Someone from AMEX team rang me and advise me of the fraud tonline shopping transaction using my card. It wasn't me at all and she blocked my card and confirmed it wasn't me.

Definitely a fraud. Called AMX who checked and asked me to forward to their fraud email which they gave me. Told me NOT to call either 1800 number or the land line.

Caller: Amex

A totally legitimate call from Fraud Protection. The number is on the Amex website and I contacted Amex as well and they confirmed it.

Caller: AMEX

This number is legit. You'll find it on AMEX's website: https://www.americanexpress.com/au/credit-cards/membership-benefits/service-and-security/fraud-protection/

I also called AMEX on 1300 364 931 before I found this page and they confirmed the number is legit. People who say it's a scam are full of it.

Caller: AMEX

This is legit.
I got a text from the usual AMEX number that gives me weekly spend update saying I had an unverified transaction and asking to call this number. I called the number on the back of my AMEX card and verified this is AMEX, don't be alarmed.
The call taker organized a replacement card straight away.

Caller: It's Amex fraud check

It's Amex

Caller: AMEX

not fraud, its the number printed on the back of most australian cards.

Caller: American Express

It's American express verifying a fraudulent transaction. They knew about other legitimate transactions on the account so it's definitely them. The 02 9271 prefix is the same beginning numbers as their fraud hotline on the back of the card as well.

Caller: 'Home Affairs'

Now number is being used as a recording from 'Department of Home Affairs' saying that my name is being used in a legal case. Just ignored it. Add this to your spam list.

Didn’t leave a message and sent a dodgey email not from Amex! Don’t ring back and don’t reply to email!

Caller: Amex Fraud Team

A legitimate call from the Fraud Support Team at Amex Australia

Caller: American Express

It's legit, it's their fraud protection department.

Caller: AMEX

This number is on. It is definitely AMEX fraud calling you.

Caller: 9271 4110

I called back to amex customer service. They said it is from them. Not a scam.
