Tesco Bank 443453666640 ☎ +443453666640

A Tesco Bank fraud alert messaged me, stating I would get a second prompt to answer Y or N. I chose N, then received another notice that a call would follow. The call was automated, so I hung up and called the number on my card; they confirmed it was Tesco Bank checking an attempted use of my card.

I received a call with no message, then called the number listed on my bill, spoke to an agent and they confirmed it was them.

I grew wary after a couple of calls from this number, but a quick Google search pointed me here, indicating it belonged to Tesco’s fraud department. Since I hold a Tesco credit card, I called the number on the back of the card and they verified that the call was legitimate. As always, it’s safest to decline unexpected calls and ring back using the number on your card.

Verified: after a rapid series of mobile alerts (ignored) and a landline call that cut off during a fraud check, I called the credit‑card customer care number on my card. They confirmed the call was legitimate and that Tesco Bank had blocked my card after two fraudulent attempts yesterday.

This is the official Tesco Bank Fraud Department number.

The Tesco credit‑card fraud team responded to a suspicious payment on my card.

That 0345 366 6640 line belongs to Tesco’s Fraud Department – like many, I ignored the call at first, then rang Tesco because my card showed unusual activity and a payment was declined. In my view it wasn’t a bother at all; actually it felt reassuring.

The number belongs to Tesco Bank’s Fraud Department. We ignored a landline call, then another rang my husband’s mobile. After dialing the number on the back of his card we learned that £200 had been donated to a GoFundMe appeal from abroad. Tesco blocked his card and the money was refunded by GoFundMe. The fraudster also had his mobile and email, which GoFundMe confirmed. It’s unclear whether the intended recipient was aware—another scam to watch out for. Thanks to Tesco for the swift action.

This is the Tesco fraud department.

Labelled as a “nuisance call” on my phone, but after investigating, I called the Tesco credit‑card team about recent transactions… many thanks.

Contact from the Tesco Fraud Department; I dialed the number on my card and they verified the above number as correct. Safe to answer.

This is a genuine Tesco Bank fraud number. Although I was initially suspicious, contacting them is advisable; otherwise they may have to block your card. They’re simply trying to protect legitimate cardholders from ongoing fraud.

Authentic call from Tesco Bank's anti‑fraud department.

When my dad received three calls from this number he thought they were scams, but after checking the comments I told him to dial the number on his card’s back; the calls turned out to be authentic. Several fraudulent transactions had already been flagged and the card was cancelled straight away. If you get a call from this number, treat it seriously and contact your fraud team immediately.

Genuine call from Tesco credit card fraud department, very helpful
