FAQ

What is the difference between registered mail and certified mail?

Registered mail is a postal service that provides proof of sending, tracking, and confirmation of delivery, often including a recipient signature. In some countries registered mail is also known as certified mail. So in many contexts registered mail and certified mail refer to the same type of service, however the exact legal value and features depend on the respective postal system.

How to track registered mail?

You can track registered mail using the official postal service tracking ID for example on Swiss Post's website. With Pingen, you also see detailed tracking updates directly in the WebApp, from dispatch to final delivery and receipt confirmation.

What is the difference between registered mail and regular mail?

Regular mail does not include tracking or proof of delivery. Registered mail provides official proof that a letter was sent, tracked during delivery and received by the recipient – making it ideal for important or legal documents.

Can you send registered mail internationally?

Yes, most postal services allow sending registered mail internationally. Delivery times, availability and tracking vary by country. Pingen currently offers registered mail to Switzerland, France, and Belgium – with full tracking and confirmation of receipt and the recipient’s signature as legal proof of delivery.
