How long does An Post delivery take within Ireland?
An Post's published standard for domestic mail is next working day delivery, and the measured result sits a little below it. ComReg's independent monitor recorded 87% of single piece priority mail delivered on the next working day in 2023 and 98.8% delivered within three working days. For an item posted in Ireland before the last collection of the day, the next working day is the realistic expectation and two working days is the realistic outside. December breaks that pattern completely: next working day performance for December 2023 was 61%.
Express Post buys a tighter, contractual window, and Same Day Delivery covers parts of Dublin within hours. Standard Post to a shared rural address without an accurate Eircode is where a day is most often lost at the far end of the journey.
Who sets the next working day target, and what it measures
ComReg, not An Post, sets the standard that the phrase "next working day" is measured against. An Post is the sole designated universal postal service provider for the State under the Communications Regulation (Postal Services) Act 2011, and ComReg is the national regulatory authority responsible for setting and monitoring its quality of service. The standard was first directed in 2004, re-consulted on in 2015, and retained unchanged: 94% of single piece priority mail delivered on the next working day, and 99.5% delivered within three working days.
An Post publishes the same two figures as its own service targets.
"We have a target of 94% for next day delivery (D+1) and a 99.5% target for delivery within three working days (D+3) for standard, domestic stamped and metered mail." (An Post, Mail Service Performance, 2026.)
The measurement is not self-reported. ComReg appointed Ipsos B&A to run the monitor, and An Post appointed KPMG to audit it against CEN technical standard EN 13850:2020. The 2023 monitor used 28,332 valid test mail items and reported an accuracy variance of plus or minus 1.1%. Two things follow from that method. The figure is a national aggregate across the whole State rather than a per-route or per-county result, and it covers single piece priority mail, which is the standard envelopes, large envelopes and packets an individual posts, not discounted bulk mail posted for deferred delivery.
An Post standard against measured outcome, 2003 to 2023
An Post fell 7 percentage points short of the 94% next working day standard in 2023, and has been below it in every year ComReg reports in its most recent notice. The gap converts D+1 from a promise into a probability: at 87%, roughly 13 items in every 100 arrive later than the following working day while the service is still performing as measured.
"An Post delivered 87% of single piece priority mail throughout the State on the next working day following the day of posting. The 2023 result is a 2% improvement on the 2022 result. However, the performance for 2023 remains 7% short of the 94% regulatory standard." (ComReg, Information Notice 24-39a, 28 May 2024.)
| Year measured | Delivered next working day (D+1) | Delivered within three working days (D+3) | Distance from the 94% D+1 standard |
|---|---|---|---|
| 2003 (first year monitored) | 71% | Not stated in the 2023 notice | 23 points below |
| 2019 (last pre-pandemic year) | 90% | Not stated in the 2023 notice | 4 points below |
| 2020 | 82% | Not stated in the 2023 notice | 12 points below |
| 2021 | 84% | Not stated in the 2023 notice | 10 points below |
| 2022 | 85% | 98.3% | 9 points below |
| 2023 | 87% | 98.8% | 7 points below |
Figures from ComReg Information Notice 24-39a, published 28 May 2024, which is the most recent annual monitor ComReg has published for An Post next working day performance. The 2023 calendar year result is the correct number to plan against; it is a measured outcome, not a commitment, and An Post's commitment remains the 94% target.
The domestic services and the timeframe each one carries
An Post publishes a stated timeframe for four domestic services, and they range from about four hours to the next working day. Same Day Delivery moves an item in roughly four hours inside a small Dublin footprint, while Standard Post to any address in the State targets the following working day with no contractual window at all. The table lists each service with its variants.
| Service | Published domestic timeframe | Tracked within Ireland | What the timeframe depends on |
|---|---|---|---|
| Standard Post, letters and large envelopes | "Next working day delivery in Ireland" | No | Catching the last collection; working days only |
| Standard Post, packets and parcels up to 20 kg | Next working day | Yes, parcels only, within the Republic of Ireland | Catching the last collection; working days only |
| Registered Post | No separate timeframe published; travels as priority mail | Yes, with signature and online proof of receipt in Ireland | A signature is required, so it cannot be left at a safe spot |
| Express Post (Next Day Delivery) | "Delivers by close of business the next working day" | Yes | Guarantee excludes events beyond An Post's control |
| Express Post timed option | Delivery before 9am or before 12pm the next working day | Yes | Selected post offices only, additional fee |
| Same Day Delivery | Drop by 11.10am for 3.10pm; drop by 1.40pm for 5.40pm | Yes | Dublin 1 to 24, Blackrock and Dun Laoghaire only |
| Redelivery after a missed attempt | Approximately 3 to 5 working days | Yes | Booked online after a "sorry we missed you!" notice |
Service details from An Post's Standard Post page, the Express Post and Next Day Delivery page, the Same Day Delivery product page and the Registered Post page. Registered Post is the service most often assumed to be faster than it is: An Post publishes compensation and signature terms for it, up to €320 for a declared value within Ireland and €25 where no value is declared, but publishes no delivery timeframe faster than ordinary priority mail. The difference between registered and ordinary mail is one of custody and liability rather than one of speed.
When the clock starts: last collections, weekends and public holidays
D+1 counts from the day of posting, not from the minute of posting, so an item that misses the last collection of the day starts its clock on the following working day. An Post's Express Post terms state that collections are not made on weekends or public holidays. An Express Post item handed in after Friday's cut-off is therefore collected on Monday, which makes Monday the day of posting and Tuesday the D+1 target, and a Monday public holiday moves both markers one day further. Public holidays are not working days, so they are excluded from both the 94% and the 99.5% counts.
Cut-off times are explicit only on the timed products. Same Day Delivery in Dublin publishes two headline drop-off windows, 11.10am for a 3.10pm delivery and 1.40pm for a 5.40pm delivery, with individual post offices operating cut-offs between roughly 12.25pm and 2pm. For Standard Post there is no single national cut-off: the deadline is the last collection printed on the individual post box or the counter closing time at the post office used.
The practical consequence is that the two most common causes of a "slow" domestic delivery are not network problems at all. They are a late Friday posting and a bank holiday weekend, both of which add working days to the count without any item ever being delayed against the standard. Delivery itself happens during the postal operative's round rather than in a booked slot, which is why the hours of delivery vary by route.
December is a different service
An Post next working day performance falls by roughly a third in December: 61% in December 2023 against 89% for January to November of the same year. The December result was identical to December 2022, so this is a structural feature of the peak season rather than a one-off failure, and it was already visible before the pandemic at 75% in December 2019.
"For the month of December 2023, the overall next-day delivery performance stood at 61%, which represents no change from the performance of December 2022. The result for pre-pandemic December 2019 was 75%." (ComReg, Information Notice 24-39a, 28 May 2024.)
Read that as a change in the shape of the distribution rather than a small slippage. In a normal month roughly 1 item in 9 misses the next working day; in December it is roughly 2 items in 5. An Post publishes recommended last posting dates for the Christmas period each year, and those dates, not the year-round standard, are the number to plan against in the second half of December. ComReg does not publish a separate December D+3 figure, so the size of the December tail beyond three working days is not measured in public.
What an Eircode does to the delivery day
Over 35% of addresses in Ireland share their address with at least one other property, which is the largest addressing risk to a next working day delivery. Eircode was launched in July 2015 precisely to resolve that, and assigned codes to more than 2.2 million postal addresses at launch.
"Each Eircode is unique to a postal address and its geographic location." (Eircode, What is an Eircode, 2026.)
The seven-character code splits into two parts that fail differently. The three-character Routing Key identifies the postal area, so an error there can route an item to the wrong delivery office and costs a full leg of the journey rather than one attempt. The four-character Unique Identifier distinguishes one property from another inside that area, so an error there usually costs the final leg only: the item reaches the correct delivery office on schedule and then depends on the postal operative resolving a name and a townland.
That asymmetry is why an incomplete address hurts rural deliveries more than urban ones. In a housing estate the street and number are already unique, so the Eircode adds little. Where more than a third of addresses nationally are non-unique, the Unique Identifier is doing the work that a street number does elsewhere. ComReg's monitor reports a single national figure for the State, so there is no published per-county or per-route breakdown of the 87%: the honest statement about a specific rural or offshore address is that its performance is not separately measured, and any figure quoted for it is an estimate rather than a measurement. Details of the code structure from Eircode.
Service standard, guarantee, and estimate are three different things
An Post applies the word guarantee to one domestic product, Express Post, and even there it is conditional. Everything else is a target, and the difference is the whole reason a 94% standard can be missed for years without any individual item being treated as late.
"The delivery guarantee does not apply where delays occur as a result of Customs intervention or events beyond our control." (An Post, Express Post terms, 2026.)
A service standard is an aggregate: 94% next working day means about 6 items in every 100 are expected to arrive later than that and the service is still performing to standard. A measured outcome is what an independent monitor recorded after the fact, which for 2023 was 87%. An estimate is anything else, including a retailer's checkout promise and any average delivery time published by a third party. None of those three is a per-item commitment except the Express Post guarantee, and under An Post's posting terms a claim on a domestic item must be made in writing to An Post within 3 months of posting. Performance targets are published on An Post's Mail Service Performance page.
What each tracking status says about the time left
Tracking runs on An Post parcels of up to 20 kg within the Republic of Ireland but not on ordinary letters or large envelopes, so most domestic single piece mail has no observable timeline at all. An Post states that tracking is updated throughout the day as post and parcels are scanned, which means the absence of an update between scan points is normal rather than evidence of a delay.
The statuses map onto the clock in a specific way. A pre-transit status, where the sender or retailer has shared details of an item with An Post, means the item is not yet in An Post custody and the D+1 count has not started. In transit and sorting statuses place the item inside the network, typically between a mail centre and the destination delivery office, and are consistent with a next working day arrival. Out for delivery is the only status that commits to a day: the item is with the postal operative and the attempt is happening on that round.
Two statuses stop the clock rather than advancing it. A missed delivery converts the timeframe from an in-transit estimate into a collection or redelivery window, and a customs or address query on an inbound item removes it from the domestic standard entirely. Full status history for a specific item is available through An Post tracking.
When a domestic item is genuinely late, and what happens next
Three working days is the threshold that matters, because the standard expects 99.5% of domestic single piece priority mail to be delivered by then. Measured performance in 2023 was 98.8%, which puts roughly 1 item in 83 outside the three working day window. An item still missing after three working days is therefore in a genuinely small minority and is worth reporting; an item missing after one working day is inside the ordinary 13% and usually is not.
Holding periods run on their own, shorter clocks once a delivery has been attempted. An Post holds Standard Post and Express Post items for 5 working days at the delivery office, Registered Post for 3 working days, and items received from abroad for 16 working days. Booked redelivery takes approximately 3 to 5 working days, which is the single largest recoverable delay in the domestic chain and the reason a safe spot registration or a nominated neighbour is worth more than an upgrade to a faster product. Holding and redelivery figures from An Post's delivery help pages.
The sequence after a failed attempt is fixed: a "sorry we missed you!" notice, then collection in person with the notice and photo identification, collection by an authorised agent with the signed notice and their identification, or a booked redelivery. Registered Post is the tightest case, because it needs a signature and is held for only 3 working days before being returned. What happens if delivery fails follows the same pattern across most postal operators, but the holding periods are An Post specific.
What the timeframe gets confused with
Six figures are routinely quoted as though they measured the same thing, and only the D+1 and D+3 standards are An Post commitments. Separating them matters because using the wrong one is how an ordinary delivery gets reported as a late one.
| Often taken to mean | What it actually is | Effect on the expected day |
|---|---|---|
| "Next day" means 24 hours | D+1 means the next working day after the day of posting | Weekend and public holiday time is not counted in the D+1 or D+3 measurement |
| The 87% figure applies to every An Post item | It is measured on domestic single piece priority mail only | Discounted bulk mail and commercial contract parcels are outside the 28,332 item sample |
| A retailer's delivery estimate is An Post's standard | It is a merchant estimate that includes order handling and dispatch | Often adds 1 to 3 days of warehouse time before An Post takes custody |
| The 94% and 99.5% standards cover inbound post from abroad | They apply to mail posted in the State for delivery in the State | Inbound items follow a different regime and are held 16 working days at the delivery office |
| Registered Post is a faster service | It adds signature, tracking and compensation up to €320 declared value | No published speed advantage; the 3 working day holding period makes a missed attempt costlier |
| A tracking number in An Post's system means An Post carried the whole journey | Some retailers use another carrier and hand the item to An Post for the final leg | Time before the handover scan sits outside An Post's standard entirely |
For a domestic parcel, the fastest check is the full scan history rather than the most recent line: the gap between the last mail centre scan and the delivery office scan is where a genuine delay shows up, and it is visible on the tracking timeline before any status text changes.
