Luxembourg country code +352 — call Luxembourg & get a number.
Luxembourg's country code is +352, and its numbering plan is one of the simplest in Europe — there are NO area codes and NO trunk 0 to strip. You just dial +352 and the number. Numbers are variable-length (6–9 digits), which is the one detail that trips up first-time callers. Here's the full dialing guide, plus how to get a +352 virtual number through MCM.

The numbers and facts you need before you dial.
What is the country code for Luxembourg?
The country code for Luxembourg is +352. You place it immediately after the international access symbol (the + on a mobile, or the exit code such as 011 or 00 on a landline) and before the subscriber's number.
Luxembourg has no area codes and no trunk 0 prefix. Unlike France, Germany, or the UK, you do not strip or add a leading zero — you simply dial the full subscriber number after +352. This flat, area-code-free plan is one of the simplest in Europe, but it also catches out callers who assume Luxembourg works like its larger neighbours.
Because the entire Grand Duchy shares a single numbering space, a number in Luxembourg City is dialed exactly the same way as a number in Esch-sur-Alzette or Ettelbruck. There is nothing regional to remember — the code +352 covers the whole country. Luxembourg is roughly 2,600 square kilometres, so its telephone network was built as a single flat numbering plan rather than being divided into regional area codes. The number you see printed is the number you dial (after the country code from abroad).
All four mean the same thing — they connect your call to Luxembourg.
How to call Luxembourg from anywhere
To reach a Luxembourg number, dial your local exit code, then 352, then the full subscriber number. From the US: 011 352 27 123 456. From the UK/EU: 00 352 27 123 456. From any mobile: +352 621 123 456. The + on a mobile automatically inserts the correct exit code for the network you are on, so it's the most reliable prefix when you travel.
Full example: +352 XXX XXXX — drop the local leading 0 when calling from abroad.
Luxembourg phone number format explained
Luxembourg numbers are variable length. Historically the country used short subscriber numbers, and lengths still differ between older and newer allocations. After the +352 code you will typically see between 6 and 9 digits, with no area code and no leading zero to add or remove. Landlines vary in length and are often written in blocks (for example 27 12 34 56 or 26 12 34 56). Mobiles are consistently longer and begin with 6 — the ranges 621, 628, 661, and 691 (all within the 6XX family) are the most common. Because there's no fixed national length, always dial the number exactly as it is published — don't pad it with extra digits and don't trim it.
Landline
Landlines use no area code. Numbers are typically written in 2-digit blocks (27 12 34 56, 26 12 34 56, etc.) and vary in length between older and newer allocations.
Mobile
Mobile numbers begin with 6 and are longer than landlines. Common opening prefixes include 621, 628, 661, and 691 across POST Luxembourg, Orange, and Tango. Number portability means the prefix indicates the original allocation but not necessarily the current carrier.
Luxembourg mobile network prefixes
The prefix after +352 tells you which network issued the SIM — though number portability means it no longer guarantees the operator.
POST Luxembourg
the incumbent (state-owned postal + telecom), broadest coverage across the Grand Duchy.
Orange Luxembourg
part of the wider Orange Europe group; strong urban and cross-border coverage.
Tango
the challenger network; competitive pricing and business bundles.
Luxembourg time zone
Luxembourg observes Central European Time (CET, UTC+1) in winter and Central European Summer Time (CEST, UTC+2) during daylight saving, on the same EU-wide schedule as Belgium, France, and Germany. In 2026, DST runs from 29 March to 25 October. Luxembourg is 6 hours ahead of US Eastern (5 during US DST) and 1 hour ahead of London year-round.
From the US East Coast, weekday 3:00–5:00 AM ET reaches Luxembourg 9:00–11:00 AM (summer). From the UK, 9:00 AM–4:00 PM UK works comfortably (Luxembourg is 1 hour ahead year-round). Tuesdays–Thursdays are the safest window for high-stakes business calls, especially into the finance sector.

Common mistakes when calling Luxembourg
Almost every failed international call is a formatting issue, not a network issue.
Adding an area code that doesn't exist
Luxembourg has none — don't insert a "city code" between +352 and the subscriber number. Every number lives in the same national pool regardless of city.
Adding a leading 0
There is no national trunk prefix to add or remove. Dial the number exactly as published, after +352.
Getting the length wrong
Luxembourg numbers are variable-length (typically 6–9 digits after +352). Trimming or padding digits is the most common reason a call fails — dial exactly as published.
Forgetting the exit code on a landline
From a fixed line you still need 011 (US/Canada) or 00 (UK/EU) before 352. On any mobile, just press + and skip both.
Assuming a 6XX prefix equals a specific carrier
Number portability across POST, Orange, and Tango means the prefix no longer guarantees which operator answers.
Tips to reduce the cost of calling Luxembourg
Use SIP/VoIP instead of legacy international rates
Luxembourg's tiny geography means the whole country is a single call zone; VoIP quality is excellent end-to-end and dramatically cheaper than per-minute international.
Get a local +352 virtual number for EU finance work
Luxembourg contacts (banks, funds, administrators) call a domestic number instead of an international one — measurably lifts pickup rates for outbound calls into the finance sector.
Bundle Luxembourg with wider EU coverage
Companies serving the EU often pair Luxembourg with Belgium, France, Germany, and Netherlands — one platform covers the whole Benelux + core EU.
Mind CET/CEST when scheduling
Luxembourg is one of the easier EU markets for scheduling — same clock as Berlin, Frankfurt, and Paris year-round; one hour ahead of London.
Why businesses get a Luxembourg virtual number
Luxembourg punches far above its size. It is a leading EU financial centre — home to investment funds, private banking, insurance, and a growing base of fintech and holding companies — and a headquarters location for institutions serving the whole European market. A local +352 virtual number lets your business present a trusted Luxembourg presence to funds, banks, and EU partners without a physical office; give customers a local number to call instead of an international one; route calls anywhere to your team's mobiles, desk phones, or a call centre across the globe; and scale up or down instantly as you enter or grow within the EU market. For any company doing business with Luxembourg's finance and cross-border sectors, a local number signals credibility and lowers the barrier for prospects to get in touch.
Anchor an EU financial-hub presence
A +352 caller ID reads as domestic to Luxembourg banks, fund administrators, and EU counterparts — pickup rates rise measurably vs. unfamiliar international IDs.
Serve the wider Benelux and EU
Luxembourg sits at the geographic and legal centre of Benelux + core EU — a +352 number is a credible base for cross-border finance, insurance, and holding-company work.
Trusted signal to funds and private banking
Luxembourg's investment-fund industry is the largest in Europe by AUM — a local number lowers the friction for fund managers, custodians, and administrators to reach you.
Cloud-based scale-up
Add IVR menus, voicemail, call recording, analytics; scale lines up or down instantly as your EU operations grow.
Route calls to any team, anywhere
Luxembourg number, US or Asia team — the caller sees Luxembourg while calls route to wherever your team actually sits.
GDPR-native + strong Luxembourg data-protection framework
Luxembourg's CNPD is one of the more active data-protection regulators in Europe — a +352 number sits inside a well-understood compliance regime.

Yes — MCM provisions +352 virtual numbers with routing to any device or team worldwide. No Luxembourg address or entity required.
Why do Luxembourg numbers look inconsistent in length?expand_more
Historical allocation — Luxembourg's small size meant subscriber numbers were kept short in the early days, and lengths were extended incrementally as capacity grew. Older numbers remain shorter than newer ones, so the 6–9 digit variability reflects when each number was issued rather than any current rule.
