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 Austria.
- 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 Austrian Post
Choose Priority when speed matters or Economy for a non-urgent paper letter. Address the envelope legibly, use the current Austrian Post format and destination zone, and add the blue Priority sticker when using Priority. Stamps and posting help are available through Austrian Post locations; use the current rate calculator rather than relying on an old quoted price.
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 Austria 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.
Austrian Post requires customs information and advance electronic data when a letter contains merchandise going outside the EU. Keep an ordinary document letter to paper correspondence; for goods, use the correct product and follow the current export and destination rules.
Delivery, proof, and pricing
For a self-mailed letter, Austrian Post lists registered mail, advice of delivery, and delivery-to-addressee options for international document letters. Availability and the delivery record produced can vary by destination.
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.
