Share Data Introduces Digital Medallion Signature Guarantees Through Universal STAMP

The UK-based securities and estate services specialist expands its Medallion Signature Guarantee offering with digital technology.

Horsham, UK – 1st October 2026 – Share Data Ltd has introduced digital Medallion Signature Guarantees through the Universal STAMP platform, expanding its existing service offering for shareholders, executors, legal professionals and financial institutions managing international securities transactions.

The development marks another step in the company’s adoption of digital technology, providing an alternative to traditional physical stamping for eligible transactions involving US and Canadian securities.

Medallion Signature Guarantees are frequently required when selling or transferring North American securities, particularly in cross-border estate administration. Obtaining the necessary certification can present additional administrative challenges for shareholders and executors based outside North America.

As an established, STAMP-accredited provider, Share Data supports individuals and professionals navigating these requirements. The introduction of the Universal STAMP digital platform extends its existing capabilities by enabling digital guarantees to be applied to electronic documents.

With worldwide availability, the platform enables Share Data to extend its digital Medallion services beyond the UK, supporting international shareholders, executors and legal professionals, subject to the receiving transfer agent’s acceptance requirements.

The platform incorporates cryptographic verification, unique transaction identifiers and audit trails. These features support document integrity, authentication and traceability throughout the digital certification process.

Orlanda Carroll, Head of UK & Foreign Business at Share Data, commented:

“Introducing digital Medallion Signature Guarantees is an important development for Share Data. We recognise that the requirements surrounding international securities transactions continue to evolve, and it is essential that our services evolve alongside them.

By adopting digital technology, we are expanding our capabilities while maintaining the specialist knowledge, verification standards and personal support that our clients rely on.”

The digital platform does not replace the underlying identity verification, legal authority checks or documentation requirements associated with Medallion Signature Guarantees. Acceptance of digitally guaranteed documents remains subject to the requirements of the receiving transfer agent.

The introduction forms part of Share Data’s continued development of its international securities and estate services, supporting clients dealing with increasingly complex cross-border financial matters.
