Call US from UK: Cheapest Methods in 2026

Calling the US from the UK on your mobile costs £1.50-3.00 per minute. That's £30-60 for a 20-minute call to your bank. Vodafone charges £3/minute standard. O2 and EE aren't much better. If you've ever checked your bill after calling a US number, you know the feeling.

You have better options. Here's what they actually cost.

Your Options at a Glance

Four ways to call the US from the UK, ranked by cost.

The maths isn't complicated. A 20-minute call to Chase costs £60 on Vodafone's standard rate. The same call through World Dialer costs $0.40 (about 32p).

Why UK Carriers Charge So Much

UK carriers treat international calls as a profit centre, not a service. They know most people don't check rates before dialling. They know you'll pay whatever shows up on the bill.

Yes, carriers offer international bolt-ons. O2's is £3/month for 1p/minute calls. Three offers 3000 minutes to the US for £5/month. But you have to set these up before you need them. Most people discover their carrier's rates mid-call, then discover the add-ons existed afterwards.

The Toll-Free Trap

US toll-free numbers (1-800, 1-888, 1-877) aren't free from the UK. You can dial them - punch in 00 1 800 and the rest - but you'll pay full international rates. Sometimes more.

Here's what happens when you dial a US 1-800 number from the UK:

• Best case: It connects, and you pay £50-00/minute
• Worse case: The company blocks international calls to that number
• Either way: Not free

Always find the company's regular +1 number instead. That's what the tables below are for.

How to Dial the US from the UK

Dial +1 followed by the 10-digit US number. Most mobiles accept this format directly.

Format: +1 (XXX) XXX-XXXX

From a UK landline, dial 00 1 then the number: Format: 00 1 XXX XXX XXXX

That's it. No access codes, no operator assistance. Just +1 and the number.

Numbers You'll Actually Need

Here are the international numbers for US banks and government agencies. These aren't toll-free numbers - they're direct lines that work from anywhere.

Note: Bank of America accepts collect calls at the number above. Chase's line is specifically for fraud and account issues.

Save these numbers. You'll need them eventually, and searching for "Chase international number" while on hold isn't ideal.

Best Times to Call

US East Coast business hours (9 AM - 5 PM) are 2 PM - 10 PM in the UK. West Coast hours (9 AM - 5 PM PT) run 5 PM - 1 AM UK time.

Call US East Coast businesses in your early afternoon. That catches them at the start of their day, before the queues build up. Calling the IRS at 2 PM UK time (9 AM Eastern) means shorter hold times than calling at 9 PM UK time (4 PM Eastern).

The UK and US switch to daylight saving time on different dates. In late March and early November, the time difference shifts by an hour for a few weeks. Check before calling if you're near those dates.

What It Actually Costs

Your carrier wants you to think international calls are inherently expensive. They're not. The phone companies that built the infrastructure have been paid. The marginal cost of connecting your call to a US number is fractions of a penny.

World Dialer charges $0.02/minute because that's what it actually costs to route a call, plus enough margin to keep the lights on. No subscription because you don't need one. No app because your browser already works.

Open worlddialer.com. Enter the number. Add a few dollars of credit. Click call. That 20-minute call to Chase? $0.40 instead of £60.
