Who does what in BCID?

An interactive, non-exhaustive map of providers and their reported roles. Explore how enterprises enter the ecosystem, get vetted, and deliver signed branded calls.

A working matrix, not an official directory. The official pages reviewed on October 23, 2026 describe roles but do not publish a named partner roster. Company assignments below reproduce the supplied compilation; individual company announcements were not independently verified for this page. An unconfirmed cell does not mean the company lacks that role.

Conceptual responsibilities, not a mandatory network sequence. Roles can overlap within one company. Terminating Service Providers (TSPs) handle display and confirmation at the receiving end; that separate role is outside this matrix.

What about ecosystem totals?

The supplied background cites historical snapshots of approximately 45 OSPs, 15 Signing Agents, 16 Onboarding Agents, and 13 Vetting Agents. These figures have no dated source attached in the supplied material and are not verified current totals. Matrix role counts describe only these 16 rows, not the full ecosystem.

Sources & next steps

The official BCID pages support the role definitions and application path, not the company-by-company assignments above. Row notes are supplied summaries of public announcements, company sites, press releases, and secondary reporting; no individual source URLs were supplied.

For an authoritative, current roster, contact BCID directly or ask a known partner such as TransNexus or Numeracle which authorized parties they work with. Authorization requires the relevant BCID/CTIA agreements after application and review, per the supplied background.
