Pay Dart Charge by phone, step by step
The phone payment route is the second-most-used after the website, and it's the only one that works reliably without internet access. 0300 300 0120, open every day 8am to 8pm. This page walks through the call, what to have ready, and how to handle the edge cases.

The automated call, step by step
The voice prompts have been stable since 2019. Roughly 3-4 minutes from dialling to confirmation.
- 1
Dial 0300 300 0120
Local-call rate. Mobile and landline both work.
- 2
Select 'Pay a charge'
Option 1. Then option 1 again for 'crossing payment'.
- 3
Vehicle registration
Speak or key in your VRM. Letters are pronounced phonetically.
- 4
Date of crossing
Day and month. System reads it back, you confirm.
- 5
Card details
Long card number, expiry, CVV. PCI-compliant entry tones.
- 6
Reference number
System reads a 12-digit confirmation. Write it down.
The reference number is your proof of payment. Keep it for at least 28 days; if a Penalty Charge Notice arrives in error, the reference is the fastest way for the appeals team to find your record.
Advance payment by phone
You can pay up to 24 hours before crossing through the phone system. Useful for early-morning trips where you don't want to stop and pay at the time, or where you're calling from a passenger seat the day before.
The deadline is the same as for all payment methods: by 11:59pm the day after your actual crossing. Pay too early (more than 24 hours ahead) and the system will reject the entry; pay too late (after the day-after deadline) and a Penalty Charge Notice follows.
When the phone is the right route, and when it isn't
Phone wins when
- You don't have mobile data or you're in a poor-signal area
- You're paying for someone else and only have their VRM
- You prefer voice prompts to forms
- You need to talk to a human (advisor hours)
- You don't have a smartphone or prefer not to pay online
Other routes are better when
- You cross frequently (open a pre-pay account)
- You want a paper receipt (use Payzone)
- You're paying multiple unrelated crossings (online is faster)
- You're paying a PCN (the crossing line won't take it; use the separate PCN line 0300 1313 120, or post/online to challenge one)
- You'd rather pay on your phone (gov.uk in a browser, or the Caura app)
Talking to an advisor instead of the automated system
The advisor service handles enquiries the automated menu can't: refunds, account amendments, PCN queries, exemption applications. Press 0 at any prompt or wait through the menus to be routed.
- Open every day, 8am to 8pm: the line runs seven days a week including bank holidays (gov.uk). Wait times are typically longest first thing Monday and late Friday afternoon.
- Outside those hours: pay online at gov.uk any time; the website has no closing time, so a late-evening crossing is easiest paid there.
- For a fine (PCN): use the separate line 0300 1313 120, same hours. A challenge to a PCN cannot be made by phone: it has to go in writing (online or by post).

Phone payment questions
What's the Dart Charge phone number?+
0300 300 0120. The line is open every day, 8am to 8pm, including bank holidays (gov.uk). Standard 0300 numbers cost the same as a local call from a mobile or landline. For a Penalty Charge Notice there is a separate line, 0300 1313 120, on the same hours.
What do I need ready before I call?+
Three things: the vehicle registration number, a debit or credit card, and the date of the crossing. If you're paying for a future crossing (up to 24 hours ahead), have the planned date ready. Have a pen for the reference number the system reads at the end.
Can I pay for someone else's crossing by phone?+
Yes. The Dart Charge phone system doesn't require ownership proof, it just needs the vehicle registration and a card. Friends, family or colleagues can call in for someone else. Just make sure the registration is exactly right; the system pays the charge against whichever VRM you enter.
Can I pay for multiple crossings in one call?+
Yes. The automated system asks if you want to add another crossing after the first payment confirms. Same vehicle, different dates: fine. Different vehicles, same call: fine. The card is charged once for the total.
What if the phone payment cuts off mid-call?+
If your card was charged before the disconnect, the payment is recorded and you'll get an SMS or email confirmation. If your card was not charged, no record exists and you'll need to call back. The most common cause is signal loss on a motorway approach. Calling from a stationary spot is more reliable.
Is paying by phone more expensive than paying online?+
No. The Dart Charge is the same per crossing regardless of payment method: £3.50 for a car, £4.20 for two-axle goods, £8.40 for multi-axle HGV. There's no surcharge for paying by phone. The 0300 number itself is charged at the local-call rate, so no premium-rate fees.
