PCN code 12: parked in a residents' or shared-use bay without a permit or payment
Checked against the official sources linked on this page on 26 October 2026. Rules change, so check the dates on your own notice.
In short: Code 12 on a council PCN in England means the council says your car was in a residents' or shared-use bay without a valid permit, voucher or ticket, and without paying. It's a higher-level contravention, so it costs more than an overstay. If you had a valid permit or had paid, the contravention didn't happen, and you can say so.
So the warden thinks you'd borrowed a resident's spot. Here's what the code means, what it'll cost, and where it tends to go wrong.
What does PCN code 12 mean?
This is the official wording, used by councils across England and by London Councils:
"Parked in a residents’ or shared use parking place or zone without a valid virtual permit or clearly displaying a valid physical permit or voucher or pay and display ticket issued for that place where required, or without payment of the parking charge."
In plain English: you were in a bay meant for residents (or shared between residents and paying visitors), and the council found no valid permit, physical or virtual, no voucher or ticket for that bay, and no payment.
A residents' bay is for permit holders only. A shared-use bay lets permit holders and paying visitors park, so in a shared-use bay paying the charge (by machine or phone) is enough.
What the letter after the code means
Some councils add a letter or number after the code (for example 12r). It narrows down what they say happened:
| Suffix | Meaning |
|---|---|
| r | Residents' bay |
| s | Shared-use bay |
| u | Electronic payment (pay by phone or app) |
| t | Voucher or pay-and-display ticket used in a permit bay |
| 4 | Virtual permit |
| w | Wrong parking zone |
| x | Incorrect registration number |
| y | Permit obscured or illegible |
| z | Out-of-date permit |
| a | Permit-holder electric vehicle charging bay |
If the suffix doesn't match what happened (it says "virtual permit" and you had a paper one on the dashboard, say), that's worth pointing out.
Similar codes you might have instead
- Code 16: permit space or zone without a valid permit. Used for bays that aren't residents' bays, such as business permit bays. Also higher level.
- Code 19: residents' or shared-use bay with an invalid permit, voucher or ticket, or after your paid time ran out. Lower level.
- Code 85: the off-street version, in a council car park. Higher level.
Is code 12 a higher or lower level PCN?
Code 12 is higher level everywhere in England. The government treats parking where you had no right to be as more serious than overstaying where parking was allowed, and the regulations for England outside London list "without displaying a permit, voucher or pay and display ticket" as a higher-level contravention.
That's why the gap between code 12 and code 19 matters. Code 19 covers having something on show (or paid) that turned out to be invalid, or running out of paid time. It's lower level, so it costs less.
How much is a code 12 PCN in London and the rest of England?
The code means the same thing everywhere in England. The price and the tribunal are what change.
| Higher level (code 12) | Lower level (for comparison, code 19) | Paid early | |
|---|---|---|---|
| London, Band A | £160 | £110 | Half price within 14 days (21 days if issued from CCTV) |
| London, Band B | £140 | £90 | As above |
| Rest of England, Band 1 | £60 | £40 | £30 (higher) |
| Rest of England, Band 2 | £70 | £50 | £35 (higher) |
London's amounts are set jointly by the London councils with the Mayor's approval. Outside London, councils pick from the two bands in the regulations, and can use different bands in different parts of their area. Your PCN will show the amount. Ignore it and, once a Charge Certificate is issued, the charge goes up by half (to £90 or £105 for a higher-level PCN outside London).
Appeals that get past the council go to London Tribunals for London councils and TfL, and to the Traffic Penalty Tribunal for the rest of England.
Does the 10-minute grace period help with code 12?
Usually not. The 10-minute grace period covers you for a few minutes after your permitted time in a parking bay runs out. It doesn't cover parking where you weren't entitled to be in the first place, and DfT's guidance says it doesn't apply if you hadn't paid a required fee or displayed a required ticket.
So if you'd paid in a shared-use bay and came back a few minutes late, you probably shouldn't have a code 12 at all (that sounds like code 19, and the grace period may apply). If you had no permit and hadn't paid, the grace period won't help.
What are the common grounds for appealing a code 12 PCN?
The ratings below are our reading of the rules, not a prediction. The council (and, if it comes to it, the adjudicator) decides each case on its own evidence.
| What happened | Why it can matter | Our reading |
|---|---|---|
| You had a valid permit on display, or a virtual permit active for that car, zone and time | The contravention didn't happen | Strong |
| You'd paid for the bay (machine, phone or app) for that time | The contravention didn't happen | Strong |
| The bay's restriction wasn't in force when you parked (outside the hours on the sign) | The contravention didn't happen | Strong, with a photo of the sign |
| The PCN came by post and the council says it's from camera evidence, with no claim the warden was prevented or you drove off | On the street, camera PCNs by post are only allowed in a short list of places, such as bus lanes and red routes. Residents' and shared-use bays aren't on it | Strong, unless the bay is on one of the listed roads |
| The signs or bay markings were missing, faded, hidden or contradictory | Councils must keep up signs that give adequate information about the restriction | Worth arguing |
| You displayed a permit or ticket but it was invalid (expired, wrong zone), or your paid time ran out | Code 19, a lower-level contravention, may describe it better. A charge higher than applies is a legal ground | Worth arguing |
| A small slip: a typo in the registration on a virtual permit, a permit that fell off the windscreen, a payment app that failed | No legal ground on its own, but councils have discretion and must consider mitigating circumstances | Worth arguing, with proof |
| You're a Blue Badge holder in a shared-use bay with a pay-and-display or pay-by-phone option, badge displayed | gov.uk says badge holders can park free at on-street meters and pay-and-display. Local rules vary, and parts of central London run their own schemes | Worth arguing, check your council's rules |
| You were only there a few minutes | The grace period doesn't cover parking without a permit or payment | Weak |
| You live on the street but your permit hadn't arrived or had lapsed | Usually a discretion point at most; include proof you'd applied or renewed | Weak to worth arguing |
| There were no other spaces | The Highway Code says you must not park in spaces reserved for residents unless entitled | Weak |

What evidence should you gather for a code 12 appeal?
Get it together before you write anything:
- The permit. A photo of the physical permit as it sat on the dashboard, or a screenshot of the virtual permit or visitor session showing the registration, zone and times.
- Payment proof. The receipt or app confirmation showing the location code, registration, start and end time.
- The signs and markings. Photos of the nearest sign plates and the bay markings, ideally with your car in shot, plus any sign that's missing, faded or hidden.
- The council's evidence. Ask for the officer's photos and notes. DfT's guidance says these should be kept as evidence.
- The PCN itself. Check the code, suffix, location, date, time and registration match what happened.
- For mitigation: emails about a permit renewal, a bank statement showing a failed payment, anything that shows the slip wasn't your fault.
How do you challenge a code 12 PCN?
The route is the same as for any council PCN in England: an informal challenge if the ticket was put on your car, formal representations once a Notice to Owner arrives, then the tribunal if the council says no. Each stage has a deadline, and the half-price window is short, so don't sit on it.

Questions people ask
Is a code 12 PCN a fine?
It's a penalty charge under civil parking enforcement (what used to be called decriminalised parking enforcement), so it isn't a criminal matter. You can pay it, or challenge it through the council and then an independent tribunal.
I had a virtual permit. Why did I get a code 12?
The council's system may not have shown a valid permit for that car, zone or time. Check the registration, zone and dates on your permit account and send a screenshot with your challenge.
What's the difference between code 12 and code 19?
Code 12 means nothing valid was shown or paid. Code 19 means something was shown or paid but it was invalid, or your paid time had run out. Code 12 is higher level and costs more.
Can I park in a residents' bay with a Blue Badge?
It depends on the council. gov.uk's Blue Badge guidance covers on-street meters and pay-and-display, not residents' bays. Check the signs and your council's rules before you park.
Can a council send a code 12 PCN by post?
Yes, if the warden was prevented from serving it or you drove away before they'd finished. On the street, a camera-only PCN by post is limited to a short list of places, such as bus lanes and red routes, and residents' and shared-use bays aren't on it.
Does challenging a code 12 PCN lose me the discount?
Outside London, councils usually hold the discount while they consider an informal challenge. In London they don't have to. Our England guide explains both.
