Ask for a document, for this customer only
Get an age answer from what they already give
Three sources, in order, until one can answer.
| Data source | What it confirms |
|---|---|
| Official identity records | The date of birth the customer typed |
| Phone and email records | A date of birth found, where one is held |
| Monnai’s age model | Likely over or under 18, when no date of birth is held |
Check age without an ID upload
Where most age checks ask for a photo of an ID and a selfie, Age Verification starts from what customers already give.
- No upload, no selfie,for the people who pass.
- Three ways to an answer.A typed date of birth checked against the official record; a date of birth found from a phone number or email; an age signal when no date is held.
- Age, beyond the gate.The same date of birth can shape age-appropriate offers and reporting, where your terms and local law allow.
- The right age, and the right person.Add Mobile KYC to check the phone belongs to the person whose age you checked.

How does age verification work without an ID?
Monnai checks the date of birth your customer types against the official record, or finds one from their phone number or email. Where no date is held, an age signal helps decide.
What happens when there is no record?
Monnai’s age model gives a likely over or under 18. If that is not enough to decide, ask that one customer for a document.

Yes, and we’d rather you did. Send past applications or transactions: we score them offline, with no integration on your side. Your full report comes back within 5 business days.
What does the age verification API return?
A plain answer for each customer: whether the date of birth matches the record, whether they are over 18, and whether a document is needed. It comes back in the same API call as your other checks.
Can you check age without asking for a date of birth?
Yes. Age Verification can find a date of birth from the phone number or email your customer already gave, where one is held, and check age from it. Your customer types nothing extra.
