In the utility industry, ensuring the integrity of security seals is paramount, and when a legal issue arises, proving that a seal’s number is unique and exclusively issued to your company is crucial. But how do you ensure your supplier can provide the necessary documentation?
As Australia’s first dedicated security seal supplier, Harcor understands just how important a well-managed and precise seal numbering system is for utilities.
Building on its local seal printing capabilities and extensive experience, Harcor’s leadership in this area stems from its Exact and Track system, which is specifically designed to manage seal numbers with precision and accountability.
Harcor’s Exact system exemplifies how serial number duplication is prevented, offering not just a seal but the assurance of seal number management.
What is certified seal numbering?

Establishing a robust seal numbering system that meets conformity and regulatory requirements is vital. For Harcor, partnering with Exact Software was essential. The system complies with NEN-EN-ISO 9001:2015 standards, including custom solutions within its certification scope.
This allows Harcor to verify the uniqueness of each security seal number provided to customers, supported by the current NEN-EN-ISO 9001:2015 certificate.
