A framing sub was due to send four men to a job in Mesa. Five turned up. The site manager counted them, shrugged, and waved the van through, because five men who can frame is better than four and the schedule was already tight.
Nobody knew who the fifth man was. Not the site manager, not the sub, and — it turned out later — not really the other four either. He’d come along with a cousin. He was on the site for nine days.
Nothing happened. That’s usually how it goes. But “nothing happened” isn’t a system, and the day something does happen, the question stops being who did it and becomes who let them in.
Access is a separate question from competence
There’s a tendency to fold everything into one decision. Can this person do the work, are they insured, are they licensed, are they trustworthy. Those are all worth knowing, and they belong to whoever is contracting the crew.
Site access is narrower and more immediate. It’s one question: is the person walking through the gate the person the paperwork says is walking through the gate? You can answer that in a couple of minutes, and it doesn’t require you to make any judgement about anybody’s character.
Keeping the two apart also keeps you out of trouble. The moment a check starts informing whether someone gets work, different rules apply, and we’ll come back to that.
The three-minute version
Ask the sub for a list of names before the crew arrives, not after. This alone catches most of it, because a name that has to be added at the gate is a name nobody planned for.
At the gate, match the person to the name and the name to something else — a phone number, an email, an address the sub has on file. One document on its own tells you very little. A borrowed licence looks exactly like an owned one.
What a mismatch actually looks like
Rarely anything cinematic. A phone number registered to someone else entirely, for years, with a vague explanation. An address that appears in no record anywhere. A name spelled two different ways across two documents from the same person. Somebody who is extremely keen to get onto the site right now and slightly evasive about which company sent them.
Any one of those on its own is probably nothing. Two together is a conversation. Three is a phone call to the sub before anyone goes any further.
Write the rule down once
The most common failure isn’t that nobody checks. It’s that the checking is inconsistent — thorough on a Tuesday, waved through on a Friday, rigorous with the unfamiliar face and casual with the familiar one.
Inconsistency is bad for two reasons. It leaves the obvious hole, and it means that when you do check someone closely, you can’t easily explain why you picked them. Set a rule that doesn’t require judgement in the moment: everyone new to the site, no exceptions, same check. Then it isn’t personal and nobody has to decide anything at the gate.
Keep the record light. A date, a name, what you matched it against. That’s it.
TellData is built for identity checks, not for employment, tenancy or credit decisions — those need an FCRA-compliant screening service.
Where a report saves the time
You can do all of this by hand. A reverse phone lookup here, a county records search there, a scroll through whatever comes up in a search engine. It works and it’s free, and on a job with six new faces in a week it will quietly eat an afternoon.
A consolidated report pulls identity and SSN trace, address history, court and criminal records, watchlist screening, and phone and email consistency into one document with a Clear, Review or Flag verdict. Two minutes, one page, and you can read it standing at the gate. This is what goes into one.
What makes it useful isn’t the amount of data. It’s that the contradictions surface on their own. A phone number that belongs to someone else is easy to miss when you’re looking at it alone and impossible to miss when it’s sitting next to the name it’s supposed to match.
Five men, four names
The Mesa job finished on time. Nobody got hurt, nothing went missing, and the fifth man was probably exactly who his cousin said he was.
The site manager still asks for the list now. Not because of what happened, but because of what didn’t.
