Penarth gives CF64 its name, and the post town keeps its own footprint rather than folding into Cardiff's. The outcode reaches from the town out to Sully and Llandough, every address in it sits under the Vale of Glamorgan rather than the city, and the distance from Cardiff city centre is about 7 miles. Three names, six wards and one council make up a delivery area with more variety inside it than the short coverage line suggests.
What CF64 actually covers
The coverage line is short: Penarth, Sully and Llandough. Penarth is the largest of the three and gives the outcode its post town, while Sully and Llandough are separate places sharing the same postcode district.
Six wards cross CF64: Castleland, Cornerswell, Dinas Powys, Llandough, Plymouth and Stanwell. Four of them — Castleland, Cornerswell, Plymouth and Stanwell — are Penarth wards, which is what a town split into its own council wards looks like. Llandough is a ward named after a place in the coverage line, and Dinas Powys is a ward that carries the name of a neighbouring community. Under the wards, the communities recorded for the outcode run from Penarth itself through Dinas Powys, Llandough, Barry and Michaelston-le-Pit and Leckwith.
None of it is administered by Cardiff. The authority for every CF64 address is the Vale of Glamorgan, and the boundary between that authority and the city runs close to this ground, which is why an address that feels like part of Cardiff can still sit in the Vale and be served from a CF64 postcode.
Why Penarth addresses don't fit a doorstep route
Three things pull a CF64 round apart, and the ward and community lists point to all of them.
The first is that the outcode holds a town and two further places in one district. Penarth alone has four wards, so the built-up part is not small; then the coverage line keeps going to Sully and Llandough, which are settlements with their own names and their own streets. A round covering all three is not a loop around one estate. It is three destinations.
The second is what sits between them. The ward named Dinas Powys and the community named Michaelston-le-Pit and Leckwith are the rural pieces of this outcode: places where homes gather in small groups with ground between them. A delivery that has to find a person at each address cannot get through that kind of territory any faster by driving more quickly, because the distance is not the only cost — the failed attempt is.
The third is the boundary effect. Because the Vale of Glamorgan and Cardiff meet near this ground, streets that look continuous can fall on different sides of a line that decides everything administrative: the council, the postcode, and therefore the collection point. Any route built on an assumption about where CF64 ends will be wrong for some addresses along the edges.
Penarth also carries the ordinary town problem in its own right. Four wards of housing mean that during the working week a share of homes have nobody in them when a van calls, and every failed attempt added to a route that already visits three destinations is what makes a doorstep model expensive rather than merely slow.
The locker that works for CF64
The answer to all of that is the same here as across the area: the parcel goes to an InPost locker, and you choose which locker when you order. The mechanism can be stated in a line — enter the postcode, see the points that serve that address, pick one, pay.
What matters is the precision of it. The list is built from the address rather than from the outcode or the ward, so a Stanwell postcode and a Llandough postcode, or one in Penarth and one at the far end of the coverage line, are matched separately. No point is chosen on your behalf, and none is carried over from a previous order to a different address.
If a street sits somewhere ambiguous — near the Vale of Glamorgan boundary, or between two of the named places in the outcode — send the postcode over and it will be checked rather than assumed. That is a better use of a minute than a second visit by a van.
Delivery to any CF64 address costs £5.00 for the order, whatever the basket holds, and there is nothing to reach before the order will be accepted. Transit through the InPost network normally puts the parcel in your chosen locker 2–3 working days after it leaves us.
Ordering is done online and takes a few minutes. Age is confirmed once, at account level, by the person placing the order, and it is not raised again afterwards; payment comes out of a wallet balance, and the wallet is filled by card or by USDT rather than by entering card details each time.
For the city's own addresses, the Cardiff weed delivery guide covers Cardiff as a whole, and the CF3 outcode page goes into the centre of the city in more detail.
Where the week goes for a Penarth order
The chain has three fixed points, and the clock on all of them starts when the order is confirmed rather than when it is paid for. First, dispatch: the parcel leaves within 24 hours of confirmation, and weekend days are not held back, so an order confirmed on a Saturday moves on the Saturday.
Second, transit. The route from there runs through the InPost network, and arrival at the cabinet you picked normally happens 2–3 working days after dispatch. Tracking covers the parcel while it travels, so its position is available without waiting for anything to come through the door.
Third, the window. The cabinet keeps the parcel for 72 hours from the moment it lands, which is generous enough for most weeks in a place of this size; the thing worth checking earlier, at the point where the list is shown, is whether the locker offered is one you actually pass. Choose on that basis rather than on distance on a map.
Penarth questions we actually get
Do Sully and Llandough addresses come back with the same collection points?
Sometimes, but it is not guaranteed and it is not the way to plan. Sully and Llandough are both inside CF64 and both appear in the same coverage line, yet each address is matched to points on its own postcode. The list you see at checkout is the one that applies to the address you entered, so an assumption taken from a friend's order a few streets away may not hold for yours.
Does a Cornerswell or Stanwell address need the full postcode, or is CF64 enough?
The full postcode, and that is true across the outcode rather than in those two wards alone. Penarth is divided into four wards and then into streets, and a cabinet can serve one street without serving the next. Give the complete postcode and the points that genuinely cover the address come back; give less and the answer is only approximate, which is not good enough when the consequence is a parcel sitting in a locker you never go near.
