This branch of An Post is more than a counter for stamps — it’s a civic utility in one of Ireland’s most affluent coastal suburbs, handling parcels, banking, and bill payments for thousands of residents.

The upshot

If you plan a Saturday trip, you have a four-hour window before the shutter comes down. For anyone juggling a working week, that Saturday morning slot — 09:00 to 13:00 — is the only out-of-hours option this branch offers.

Is Saturday an An Post working day?

Yes, but with a critical distinction: the Dun Laoghaire post office on George’s Street Upper opens Saturday from 09:00 to 13:00, according to An Post’s official Store Locator (government postal service). That is a four-hour window, not a full day. The branch does not open on Sundays or public holidays.

Does An Post deliver on Saturday?

An Post operates a Saturday parcel delivery service in most urban areas, including Dún Laoghaire, though tracked services may have different cut-off times. The branch at George’s Street Upper processes outgoing mail on Saturday during opening hours. Last daily collection from the branch is 17:30 on weekdays; Saturday collection times align with the 13:00 closing.

The implication: Saturday is a working day for counter service and collection, but the reduced hours mean plan your visit for the morning window. If you need to send something tracked, arriving by 12:30 gives the counter staff time to process it.

What region is Dun Laoghaire in?

Dún Laoghaire sits in County Dublin, specifically within the Dún Laoghaire–Rathdown administrative area — one of four local government units that make up the county. The post office at 100 George’s Street Upper serves as the main postal hub for this area.

Is Dun Laoghaire in County Dublin?

Yes. Dún Laoghaire is a coastal town in County Dublin, approximately 12 kilometres south of Dublin city centre. It falls under the jurisdiction of Dún Laoghaire–Rathdown County Council.

What is Dún Laoghaire–Rathdown?

Dún Laoghaire–Rathdown is one of the four local government areas of County Dublin, alongside Dublin City, Fingal, and South Dublin. It covers the southeastern part of the county, including wealthy suburbs like Dalkey, Killiney, and Dún Laoghaire itself.

The pattern: Knowing your local council area matters for postal services, because An Post coordinates with local delivery routes and collection schedules by county subdivision. Residents of Dún Laoghaire–Rathdown see their mail routed through the Dublin South distribution centre.

Where can I post a letter in Ireland?

An Post operates over 1,100 post offices nationwide, and the Dun Laoghaire branch at 100 George’s Street Upper is the primary option for this area. It accepts letters and parcels at the counter, and there are nearby alternatives if you need a different branch.

Can I post a letter at Dun Laoghaire post office?

Yes. The branch handles standard letter post, registered post, and parcel services. An Post’s official Store Locator (state postal operator) confirms the branch offers courier post as well.

What other post offices are near Dun Laoghaire?

  • Dalkey Post Office — approximately 2 km south on Castle Street
  • Glenageary Post Office — approximately 2.5 km west on Glenageary Road
  • Glasthule Post Office — approximately 1.5 km north on Glasthule Road

Why this matters: If the George’s Street Upper branch is closed on a Sunday or you miss Saturday’s 13:00 cut-off, Glenageary and Dalkey branches also operate Saturday mornings — but check their specific hours via the An Post locator, as they vary.

How much is a stamp in Ireland?

Stamp prices are set by An Post and vary by weight and destination. The Dun Laoghaire branch sells stamps over the counter, and prices are identical across all An Post locations.

What is the cost of a national letter stamp?

A standard national letter stamp (up to 100g) is priced at €1.40 as of the latest An Post price schedule. The Dun Laoghaire post office sells these at its counter.

What are the prices for international stamps?

International stamp prices depend on the destination zone (Zone 1: UK; Zone 2: Europe; Zone 3: Rest of World) and weight. A standard letter to the UK (up to 100g) costs €2.20, to Europe €2.50, and to the rest of the world €3.80. These rates are set by An Post (national postal authority) and apply at all branches including Dun Laoghaire.

The trade-off: Buying singles at the counter is the most straightforward, but if you mail regularly, consider An Post’s online stamp printing service or a bulk purchase — the price per stamp is the same, but you save a trip to George’s Street Upper.

What is Dún Laoghaire famous for?

Dún Laoghaire is best known for its Victorian granite pier, harbour, and the popular East Pier walk — a 3-kilometre round trip that draws walkers and cyclists year-round. It also hosts a busy ferry port connecting to Holyhead in Wales.

Is Dún Laoghaire a posh suburb?

Yes. Dún Laoghaire is widely regarded as one of Dublin’s most affluent suburbs, with median house prices among the highest in the county. Its Victorian architecture, seafront location, and proximity to Dublin city centre (30 minutes by DART) make it desirable for professionals and families.
