About

Everything about calling Chase UK from abroad

The app first, this number second

Chase UK is an app-based bank, a trading name of J.P. Morgan Europe Limited. Its contact page sends customers to the Support tab in the Chase app first, where you can call or message and are fast-tracked through security checks. The phone number, 0800 376 3333, is for when you do not have the app to hand, or do not yet bank with Chase.

Why you might ring Chase from abroad

Chase gives this number for when the app is not to hand, which can happen if your phone is lost, stolen or broken while you are away. Chase's contact page says "We're open 24/7", holidays included.

Chase calls the in-app Support tab the quickest way to reach it, because you are fast-tracked through security checks.

Calling a UK 0800 line from a foreign network

Chase says calls to 0800 numbers are free from mobiles and landlines within the UK, and gives a separate number for callers abroad, +44 203 493 0829. It does not say whether 0800 376 3333 connects from a foreign network.

What Losali does with this number

Losali is an independent dialler that runs in a web browser. Your call goes over the internet and Losali's telecom carrier connects it to Chase's 0800 number, so your foreign network only carries data. No app to install and no UK SIM to buy, so a laptop or a borrowed phone will do when your own phone is the problem.
