What Is Registration Capacity?

Registration capacity is a security and access-control feature within the ON24 Intelligent Engagement Platform that allows event organizers to set a maximum number of registrants for a webinar. Once the capacity is reached, the registration page can stop accepting new sign-ups or direct visitors to alternative experiences.

This feature ensures that organizations can manage access in a way that aligns with event goals, compliance requirements, or audience expectations. Registration capacity is most commonly used for programs where attendance must be limited for operational, technical, or strategic reasons.

Why It Matters

Controlling registration is critical for many digital event programs. Some webinars are tailored to specific customer groups, partner audiences, or internal teams—making it necessary to limit sign-ups. In other scenarios, registration capacity helps prevent unexpected spikes in demand that could impact event logistics or attendee experience.

Registration capacity also improves security. By preventing unlimited registrations, organizations can avoid spam sign-ups or unauthorized access attempts. For programs that involve sensitive information or invite-only participation, such limits help maintain the integrity of the audience.

Within ON24, registration capacity works alongside other webinar capabilities that enhance event quality and audience engagement. To understand the broader ecosystem in which this feature operates, refer to the ON24 webinar capabilities page.

How It’s Used

• Restricting Attendance For Exclusive Events: Registration capacity ensures that only an approved number of participants can register. This is useful for high-touch sessions such as executive briefings or customer roadmap discussions.
• Managing Webinar Logistics: Teams can set capacity limits to better anticipate Q&A volume, engagement activity, and internal staffing needs. This helps presenters and moderators manage live interactions more effectively.
• Directing Overflow Traffic: If an event fills quickly, organizers may use capacity limits to redirect visitors to another event, such as an upcoming session listed on the Upcoming Webinars page.
• Supporting Training And Certification Programs: Educational or certification sessions often require smaller, controlled groups. Registration capacity helps ensure that instructors or facilitators can manage participant volume. To explore how ON24 supports training pathways, teams often consult content such as the Propel Your Pipeline page.
• Enhancing Security And Compliance: In regulated industries, only specific individuals may be allowed to join certain events. Registration capacity helps ensure access remains controlled and compliant.
