If you’re nervous about getting the address, postage or customs wrong, this guide shows exactly what to do so your letter arrives in Denmark without stress. You’ll get concrete steps for domestic and international mail, how to buy postage, what you can and can’t send, and a checklist of what to bring.

Key facts

PostNord is the main carrier for Danish mail; private couriers are an option for express or tracked international shipments.
Domestic standard letters typically move within a few working days; express options exist for next-day delivery.
For international mail, check customs rules and include a full return address.
You can buy postage codes via the PostNord app or at post offices – printing a code replaces traditional stamps for many services.

How do I send a letter to Denmark?

Decide first if you need a simple domestic drop, tracked delivery, or an international courier. For routine correspondence inside Denmark you can use PostNord’s regular services (postbox drop or post office). For urgent or valuable documents, choose tracked or registered options that require signatures and give you a shipment number.

Quick decision tree:

If sending inside Denmark and it’s not time-sensitive: buy a postage code or stamp, write the address correctly, drop in a PostNord mailbox.
If you need proof of delivery: choose registered mail (recommended for contracts, legal papers) and keep the tracking number.
If sending from abroad: check customs rules for the destination country and consider an international courier for time-critical deliveries.

Should I make use of direct mail in Denmark?

Direct mail (a service for sending letters, invoices, brochures or subscriptions to named recipients) is useful if you need bulk, scheduled or branded delivery. As an expat you’ll mainly use it for single-item registered post, not bulk marketing – but the mechanics are similar: clear addressing, barcode space on the envelope, and the correct postage code.

When to choose direct/registered mail:

You must prove delivery (signed receipt).
You’re sending important legal or financial documents.
You want tracking and delivery notifications.

Make sure you leave room on the envelope for processing labels and barcodes. If you need postal codes for Danish towns, use a reliable lookup such as the postal code lookup.

Sending letters to Denmark vs. sending letters internationally – what you need to know

The biggest differences are transit time, customs checks, and how you buy postage.

Sending letters to Denmark

Inside Denmark you can:

Buy a physical stamp at a post office, kiosk, or supermarket – or buy a postage code via the PostNord app and print or write the code on the envelope.
Drop regular letters in a red PostNord postbox or hand them in at a post office.
Choose registered/insured options for valuable items; these usually include tracking and require a signature on delivery.

Typical steps for domestic posting:

Write the recipient address clearly (see addressing section below).
Purchase postage (stamp, postage code or pay at a counter).
Drop in a PostNord mailbox or hand over at a post office; keep receipts and tracking codes.

Sending letters abroad

When posting into or out of Denmark across borders:

Check customs rules: some countries require customs forms for parcels; letters with goods may be inspected.
Prefer tracked or express services for important international mail – these show the item’s route and usually clear customs faster.
Write the destination country in capital letters on the last line of the address.

If you’re leaving Denmark and want mail forwarded, see practical advice in our guide on leaving Denmark. For city vs rural addressing quirks, a quick read about major cities can help (some districts use building names or neighbourhood cues).

Checklist – before you post

Recipient’s full name and correct postal code (verify with a postal code lookup).
Return address written clearly on the back or top-left of the envelope.
Appropriate postage (stamp or printed postage code) and any customs forms if sending goods.
Secure sealing – use an envelope sized to the contents (no overstuffing).
Your phone to record tracking numbers or a photo of the posted envelope.

What is allowed when sending letters to Denmark?

Most paper documents, photos and similar items are allowed. Prohibited items and restrictions depend on service and origin/destination country. Examples:

Allowed (generally): letters, invoices, certificates, photos, printed media.
Restricted or require declaration: money, cheques, valuable metals, sensitive electronics or batteries, food, or anything with commercial value.
Prohibited: certain chemicals, hazardous materials, and other items listed by postal authorities and customs.

Always check PostNord and the destination country’s customs pages before posting anything valuable. If you declare goods incorrectly you may be liable for fines or the item being returned.

How do I address the letter properly so that it arrives in Denmark?

Clear addressing reduces delivery delays. Use dark ink on a light background and write in Latin characters. Danish addressing format (domestic):

Line 1: Recipient name
Line 2: Street name and house number, apartment (e.g., St. Thomas Vej 12, 3.tv)
Line 3: Postal code and town (e.g., 2100 København Ø)
Optional: Country only for international mail on the final line (e.g., DENMARK)

Formatting tips:

Use consistent font size (10-12 pt if printing) and avoid underlining.
Write the postal code before the town name (e.g., 8000 Aarhus).
For international senders, put the destination country in capital letters on the last line.

If the recipient lives in a multi-unit building, add apartment or floor designations (3.tv means 3rd floor, right). For extra certainty, confirm the address with the recipient or check municipal records at borger.dk for official formats.

Frequently asked questions about sending a letter in Denmark

What are the postage rates to Denmark?

Rates change periodically. Domestic standard letter rates and international rates are published by PostNord and vary by size, weight and service level (standard, registered, express). If you buy services online you may see a higher price because tracking and signature options are included.

Can I use a regular stamp for international postage to Denmark?

Yes – a regular international stamp can be used when sending letters to Denmark from abroad, provided the stamp covers the correct rate for weight and service. If you need express or tracked delivery, buy a higher-class stamp or use a courier service that includes tracking.

How many stamps do I need to post a letter to Denmark?

Number of stamps depends on weight and size. Small standard letters usually need one standard stamp; anything heavier or larger requires additional postage or a postage code. When in doubt, weigh the item or pay at the post counter to avoid underpayment.

Do I need to pay customs when posting a letter to Denmark?

Letters that contain goods or commercial samples may be subject to customs inspections and duties. Purely personal letters and documents generally aren’t taxed, but rules differ by origin country and the recipient’s import thresholds.

Where do I get the right materials for posting items to Denmark?

Buy envelopes, padded mailers and boxes at stationers, supermarkets, hardware stores or post offices. PostNord post offices sell appropriate packaging and labels; many retail shops sell stamps and basic mailing supplies too.

Tip: If you plan to send several items, register for the PostNord app – buying postage codes there is quicker and often cheaper than paying at a counter, and you get digital receipts.

Warning: Don’t overstuff envelopes or use unusual materials – automated sorting machines can reject or damage poorly prepared mail.

Next step

Decide whether you need standard, tracked or express service; check the recipient’s postal code, buy postage via the PostNord app or at a post office, and keep the tracking number.
