A configured international fallback may be used when local-production requirements are not met. Checkout confirms the service available for the addresses and PDF. ## Available mailing options - **Standard local mail** for ordinary letters. - **Expedited mail** for eligible faster delivery.

Upload the PDF using the file selector on this page. 3. Enter the recipient's complete mailing address in the United Kingdom and your return address. 4. Review the rendered pages, print settings, available delivery services, and exact price. 5. Pay only after the address, document, and mailing option are correct. PostalForm then prints, envelopes, posts, and tracks the production handoff. ## Address and document requirements Use a complete UK address with the recipient name, premises and street, locality when needed, post town, and postcode. Upload a single finished PDF. Checkout validates the address, page count, file size, and printable dimensions before payment. ## Pricing and delivery estimates The price depends on the PDF page count, color or black-and-white printing, single- or double-sided printing, destination, and selected delivery or proof service. PostalForm shows the exact price and an estimated delivery window before payment. Carrier dates are estimates rather than guarantees, and registered or certified proof services cannot be combined with expedited delivery. ## Sources Local delivery information is based on [PinGen's hybrid-mail network](https://www.pingen.com/en/) and PostalForm's current provider configuration. Checkout confirms order-specific eligibility. ## FAQs - **Can I mail a letter to the United Kingdom without a printer?** Yes.
