To prevent theft and ensure safe operations, postal systems can implement various security measures. One such measure is to use tamper-evident bags that seal automatically when opened.
According to the guidelines, these bags should be used for all high-value items. This can help prevent theft and ensure that packages are not tampered with during transit.
Regular security audits and risk assessments can also help identify vulnerabilities in the system. This can involve reviewing security protocols, monitoring for suspicious activity, and making adjustments as needed.
Implementing a secure chain of custody for mail and packages is also crucial. This means having a clear process for tracking items from collection to delivery, and ensuring that they are handled by authorized personnel.
Security Measures
Security Measures are crucial in maintaining the integrity of postal systems. Appointing a Mail Security Coordinator and organizing a Mail Security Response Team can help prevent and respond to security incidents.
To secure your mail center, control access by using sign-in sheets, badges, and/or card readers. Limit access to employees, known visitors, and escorted visitors, and restrict drivers to a separate area. Use video cameras inside and outside the facility/docks to monitor activity.
Some key security measures include: Locking all outside doors and/or prohibiting doors from being propped openRestricting deliveries to a defined areaX-raying all incoming mail (for large mail centers)Maintaining a Suspicious Package Profile These measures can help prevent theft and ensure the safe delivery of mail and packages.
Certification
Certification is a crucial step in ensuring the security of the postal sector.
The Universal Postal Union (UPU) offers security certification to help member countries improve security and measure compliance with UPU security standards S58 and S59.
A certification procedure can be initiated only after submitting a completed self-assessment for each critical facility seeking certification.
Required documentation must be current, complete, and available for review.
The self-assessment assesses whether the organizational system meets the mandatory minimum security requirements.
In some cases, a Designated Operator (DO) may be required to comply with security requirements of national legislative or regulatory civil aviation authorities or external organizations like ICAO or IATA.
The UPU recognizes that these third-party standards may be more rigorous than S58 and S59, but if a DO complies with them, it may be possible to obtain an equivalency recognition of S58 and S59 certification.
Certified critical facilities are listed on the UPU website, along with their associated DOs, certification year, level achieved, and certification validity dates.

Mail Center Theft Prevention Guidelines
As you're responsible for managing your company's mail center, you want to ensure that it's secure and free from theft. One way to achieve this is by knowing your employees, so make sure to conduct a thorough background check on new hires before assigning them to the mail center.
To prevent unauthorized access, secure your mail center by keeping it locked whenever possible, especially when no one is on duty. Maintaining a sign-in sheet for persons entering and leaving the mail center is also a good idea, including times of arrival and departure.
One effective way to protect valuable mail is by using Registered Mail, which should be kept separate from other mail. This way, you can document the transfer of Registered Mail by requiring the receiver to sign for custody.
It's also essential to protect company funds handled as part of the mail center operations by establishing adequate controls to fix individual responsibility for any losses that may occur.
