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 Spain preselected for the recipient address. Your sender-address suggestion remains separate, so enter the real return address in the Netherlands.
- 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 PostNL
Address and seal the document envelope, apply the current number of International 1 stamps or a valid stamp code for its weight, and place an eligible letter in an orange PostNL letterbox or take it to a post office. Use a PostNL point when you need advice, registered handling, insurance, or priority service.
How to address a letter to Spain
Enter the recipient's full name, street and building number, floor or door details when needed, five-digit postcode, and locality. Upload one final PDF with the pages in order. Before payment, PostalForm checks the address, page count, file size, and printable dimensions and flags anything that needs correcting.
Documents, goods, and customs
Both the Netherlands and Spain 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.
A PostNL letter franked with stamps may not contain goods. Merchandise requires a barcode shipping label, advance information, and—when applicable—the correct customs form even if it fits in an envelope.
Delivery, proof, and pricing
For a self-mailed letter, PostNL offers international registered mail with proof of shipment, track and trace, and a delivery signature, plus other priority or insured choices. Destination handoff can affect the available events.
PostalForm currently offers standard and Registered Mail options for eligible letters to Spain. 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.

FAQs
- Can I mail a letter from the Netherlands to Spain without a printer?
- Yes. Upload the finished PDF on this page. PostalForm keeps it attached when you continue, presets Spain for the recipient address, and shows the eligible service and exact price before payment.
- Will PostalForm physically post the letter in the Netherlands?
- Not necessarily. Your return address can be in the Netherlands, but PostalForm may print and mail the letter from a different location. If a postmark from the Netherlands is required, send the letter directly through PostNL.
- Do I need a customs form for this letter?
- Both the Netherlands and Spain 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. A PostNL letter franked with stamps may not contain goods. Merchandise requires a barcode shipping label, advance information, and—when applicable—the correct customs form even if it fits in an envelope.
- Can I get tracking or proof of delivery?
- PostNL offers international registered mail with proof of shipment, track and trace, and a delivery signature, plus other priority or insured choices. Destination handoff can affect the available events. PostalForm currently offers standard and Registered Mail options for eligible letters to Spain; checkout confirms the choices for the actual order.
- Does the recipient country stay selected after I upload?
- Yes. The article upload handoff presets Spain 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.
