That's quite likely accurate.  My AT&T badge let me in via unattended
entrances at a variety of facilities; I'd expect that a tech's badge would
indeed work for many COs.

A better answer is for the COLO management to supply a number, on
request, to tenants; they'd pass this number on to their supplier, for
one-time use by the tech.

A government-issued ID (at most) proves your identity; it says nothing
about your authorization to be somewhere.  A company-issued ID (at most)
proves that you work for some company that may or may not (a) be present
at the COLO, and (b) may or may not be there for legitimate reasons.
What's necessary here is *permission*.
