State governments across the U.S. are updating their Certified Mail® requirements at an unprecedented pace, with major changes taking effect in Washington, Minnesota, and Maine just this year. These updates impact everything from eviction notices to medical debt collection, creating new compliance challenges for businesses that rely on Certified Mail for legal notifications.
Whether you’re a property manager, healthcare provider, debt collector, or attorney, keeping up with these changing rules is crucial to stay compliant and avoid expensive legal problems.

Legal professionals, healthcare providers, property managers, and financial institutions rely on Certified Mail because it provides court-admissible evidence that critical notices were properly sent and received. This documentation proves essential in:

Q: What is Certified Mail, and how is it different from regular mail?
A: Certified Mail is a USPS service that provides proof of mailing and delivery confirmation with tracking, while regular mail offers no delivery verification. USPS Certified Mail costs an additional $5.30 plus postage as of October 2025.
Q: How long does Certified Mail take to deliver?
A: Certified Mail follows the same delivery timeframes as First-Class Mail® (1-5 business days domestically), but may take slightly longer due to the signature requirement and tracking processes.

A: No, USPS Certified Mail is only available for domestic shipments within the United States. For international shipments requiring proof of delivery, consider Global Express Guaranteed or Priority Mail Express International.
Q: Does Certified Mail require a signature?
A: Yes, Certified Mail requires a signature upon delivery. The recipient or an authorized agent must sign to confirm receipt, which creates the proof of delivery that makes Certified Mail legally valid for important notices and documents.
Q: What happens if the recipient refuses Certified Mail?

A: Retain Certified Mail documentation for at least 7 years for business purposes, though legal matters may require longer retention periods. Consult your attorney for case-specific guidance.
