In the Harappan civilization, seals and sealings played a vital role in facilitating long-distance communication and trade. Items were typically sealed with clay to ensure their integrity during transport, creating a system of identification for goods. The seals often featured animal motifs and inscriptions that likely indicated the name or title of the owner. While the script remains largely undeciphered, it appears to be non-alphabetical, suggesting a complex system of communication among Harappans. The significant number of materials and objects bearing these seals, including copper tools and even signboards, implies that literacy may have been more widespread than previously thought. Notably, a standardized system of weights was also linked to these practices, facilitating trade and economic regulation in the civilization.
