Everything about calling Capital One UK from abroad
What Capital One wants you to call this number for
On its Contact us page, Capital One UK lists four reasons to ring 0800 952 5267: the transaction is not on your account, you do not recognise the transaction or the amount, you have been the victim of a scam, or you cannot reach the retailer or merchant. Capital One's page data also labels this number as its lost or stolen card line. Its ‘Need to report fraud?’ tab lists a separate 0800 number for account fraud, with similar triggers (an unrecognised transaction, a stolen card, a scam), and payment difficulties have a third. General account questions go to an 03 number.
Opening hours, and what works out of hours
This is not a round-the-clock line. Capital One gives set hours for its phone team: Monday to Friday 7am to 9pm, and Saturday and Sunday 8am to 5pm. Outside those hours, it says, the automated options still let you do things such as make a payment. In the app, under My card, then Report lost or stolen, you can lock the card temporarily so no one can use it.
Checks before you report an unknown payment
Capital One suggests a few questions first. Did an extra cardholder make the payment? Does the company trade under another name? Has a free trial turned into a paid subscription? Did you agree to the charge with a retailer, or mistype a payee? If the payment still makes no sense, call. For a payment you did make but have a problem with, Capital One says to try the retailer first, then fill in its online dispute form, save it as a PDF and email it to UKDisputes@capitalone.com; a dispute cannot be raised while the transaction is still pending.
- Lock the card in the app if it is missing or a payment looks wrong.
- Note the date, amount, currency and merchant name of the payment.
- If it was a scam, keep the messages, links or receipts involved.
- Check Capital One's phone hours first: weekday evenings run to 9pm, weekends close at 5pm.
Dialling from outside the UK
Capital One says calls to 0800 are free from a UK landline or personal mobile, and lists +44 115 993 8002 as its ‘Call from abroad’ number under General account query. It says nothing about reaching 0800 952 5267 from a foreign network. Losali is an independent dialler in your web browser: the call runs over the internet and Losali's telecom carrier connects it to the 0800 number, so your foreign network carries only data, with no app or UK SIM involved.
What kind of number is this?
Freephone 0800 / 0808. Free to call from inside the UK. Losali shows the price before the call starts.
