Option 1: Mail the letter online
- Finish the letter and printable attachments as one PDF.
- Upload the PDF using the file selector on this page.
- Continue to PostalForm with Luxembourg preselected for the recipient address. Your sender-address suggestion remains separate, so enter the real return address in Germany.
- Review the rendered pages, address, eligible mailing services, estimated delivery window, and exact price.
- Pay only after everything is correct. PostalForm then prints, envelopes, and posts the letter.
Option 2: Send it through Deutsche Post
Put the destination country in capital letters on the final address line without adding an old-style country prefix to the postcode. Choose the Deutsche Post international letter format that matches the sealed envelope's dimensions and weight, apply current postage, and use a mailbox or retail acceptance point allowed for that product. Add registered service before posting when a mailing record is needed.
How to address a letter to Luxembourg
Use the recipient name, street and building number, four-digit postcode, and locality. Prefixing the postcode with L- is not necessary when the country is already selected. Upload one final PDF; checkout validates the addresses, file size, page count, and printable dimensions.
Documents, goods, and customs
Both Germany and Luxembourg are in the EU customs territory, so a document-only letter normally does not need a customs declaration. Special territories and any contents other than correspondence can follow different rules.
Use an international letter for written correspondence and check Deutsche Post's separate current guidance before inserting goods. Merchandise, valuables, and restricted contents can require a different product, electronic data, or customs documents.
Delivery, proof, and pricing
For a self-mailed letter, Deutsche Post offers international registered service and other add-ons for eligible letters. Tracking depth and delivery evidence depend on the destination postal network, so verify the current country conditions.
PostalForm currently offers standard local mail for eligible letters to Luxembourg. Checkout is authoritative for the actual PDF and addresses and shows the eligible service, estimated delivery window, and exact price before payment.
Before you send
- Use a final PDF or a sealed paper letter with every page in the correct order.
- Confirm the recipient name, postcode or PIN code, locality, and country.
- Keep goods, cash, hazardous materials, and anything needing a customs declaration out of a document-only letter.
- Use the carrier's current calculator for a self-mailed letter, or PostalForm's checkout for an online order; rates and eligibility can change.
- Choose a proof service only when its delivery record matches what you actually need.

- Yes. Upload the finished PDF on this page. PostalForm keeps it attached when you continue, presets Luxembourg for the recipient address, and shows the eligible service and exact price before payment.
- Will PostalForm physically post the letter in Germany?
- Not necessarily. Your return address can be in Germany, but PostalForm may print and mail the letter from a different location. If a postmark from Germany is required, send the letter directly through Deutsche Post.
- Do I need a customs form for this letter?
- Both Germany and Luxembourg are in the EU customs territory, so a document-only letter normally does not need a customs declaration. Special territories and any contents other than correspondence can follow different rules. Use an international letter for written correspondence and check Deutsche Post's separate current guidance before inserting goods. Merchandise, valuables, and restricted contents can require a different product, electronic data, or customs documents.
- Can I get tracking or proof of delivery?
- Deutsche Post offers international registered service and other add-ons for eligible letters. Tracking depth and delivery evidence depend on the destination postal network, so verify the current country conditions.

- Yes. The article upload handoff presets Luxembourg in the recipient-address country filter. It does not preset the sender country, so the sender field can keep using the normal location suggestion until you choose or enter your actual return address.
