Registered Mail provides added protection for valuable and important mail with evidence of mailing and delivery. Registered Mail pieces require specific packaging and sealing methods for security and protection. When not in transit, Registered Mail pieces must be stored in a locked safe, room, or cage separated from other mail.
Registered Mail is sent separately from regular mail. Due to additional protection, it takes about 2-3 weeks for Registered Mail to be delivered. If security is not a major concern, but mail tracking is preferable, Certified Mail might be a better choice.
USPS tracking number will be emailed to you 3 bussiness days after your Registered letter was sent.
Unfortunately, the service is currently only available for mail sent domestically within the United States.
