Enter the role, then ask a named person who was there to confirm it. Until somebody does, it is a claim, and it reads as one.
That is the whole mechanism. There is no upload that proves a role, no document check, and no plan that skips the step.
Who to ask, by the kind of record
Credda names the right witness for each kind of record, because the honest answer is different each time.
A job or a role: a former manager, a client or a colleague.
A certification: the issuing body.
Education: the registrar or the institution.
A project or a piece of work: a client, a collaborator, or anyone who saw the work.
An award: an organizer, a judge or the awarding body.
Pick the person who would answer honestly if a stranger rang them. A colleague who worked beside you for two years is worth more to your record than a director who barely knew you, and Credda cannot tell the difference, so this is on your judgment.
What happens to the person you name
They get one email with a link. They do not need a Credda account and they never will. The link for a record like this lasts seven days, and links for confirming a finished job or an invoice last thirty.
They can do one of three things.
Confirm. They are asked to confirm a fact. There is no rating, no score and no question about what they think of you.
Decline. Decline is not a mark against you. There is no adverse event, nothing is recorded against you, and none of the reasons they can pick is a finding. "It may well have happened, but I cannot personally vouch for it" from a manager six years on is an honest answer, not an accusation. Declining also stops any further chasing about that record.
Nothing. Silence is never turned into a yes. There is no path anywhere in Credda that converts an unanswered request into a confirmation.
Contact is capped at the first ask plus two follow ups, and the last one says outright that it is the last message and that ignoring it records nothing against anybody. If you resend by hand, you are spending the same three, not adding to them.
There is no unsubscribe link for a witness, because they never signed up to anything. Bear that in mind before you name somebody: three emails from a company they have never heard of is the most they will get, and it is still three emails. What the person you asked actually sees is the page to send them if they ask you what this is.
If you employ people, confirming for them
If you run a practice, a shop or an agency, you can confirm work for people on your roster from the organization console. That is a genuine third party confirmation, because the organization is not the person.
There are three possible results, not two: blocked when the person confirming is the worker, recorded but not counted while the organization itself has not been corroborated as a real employer, and verified when the parties are distinct and the organization has cleared that bar. Why a shift you recorded may not count sets out the four ways an organization clears it, and warns about the one route that looks like a way out and is not.
What a confirmed role is actually worth
Less than most people expect, and the reason is the point of the product.
The score reads employment once, as a yes or a no: is there at least one third party confirmed role on this record. One confirmed role counts as much as fifty. A self-entered one counts as zero. The employer's name is never read, so a famous practice and a two person workshop are worth exactly the same. How long you were there is never read either.
Education, skills, certifications, projects and awards do not move the score at all, verified or not. They are on a published exclusion list. They are recorded and displayed because clients ask about them, and they are not scoring inputs.
So one confirmed role is worth getting, and the tenth is worth nothing to your score. After that, the thing that moves your record is finished work your clients confirmed.
If something confirmed about you is wrong
If a witness confirms your work but corrects a detail, you see the correction on the record and you can accept it or dispute it. You are told before you choose that neither answer changes the recorded facts, your verification or your score, because both are a right of reply rather than a veto. The person is identified to you by role only, never by name. What to do if something on your record is wrong covers that and the two other situations it gets confused with.
