Eight checks your risk team can trust
Authentication and fraud signals that come straight from the operator at the moment of decision, not from a stale database.

Match a phone number to a 13-digit national ID or a company registration number, without receiving any personal data back.
Returns: match / no match
TRUE-DTACAIS · coming soon
Mobile Subscriber Status
How long has this SIM been in service?
Prepaid or postpaid, active or not, and how long the line has been in service. A number in service for 11 days is a very different risk from one in service for six years.
Returns: line type, status, service age

Number Verification
Is this device using this number right now?
Silent, OTP-free verification over the phone's mobile data connection. Infos detects the network and hands the check to the right operator automatically.
Returns: verified true / false

SIM Swap
Was the SIM changed recently?
Catch account-takeover attempts before you send an OTP or approve a transfer: check for a swap within a window (up to 30 days), or get the date of the last swap.
Returns: swapped yes / no, last swap date

Where each check fits
Put telco signals at the moments that decide risk: onboarding, login, and changes to accounts and limits.
Banks & financial institutions
Mule farms churn cheap prepaid SIMs. A low service age plus a prepaid line at account opening is a combination no other Thai data source can show you.
- Account opening: is the phone really theirs? → Thai ID Verification
- Mule-risk screening: → Mobile Subscriber Status
- Login & device binding: → Number Verification, SIM Swap
Leasing & hire-purchase
Check the applicant and the guarantor at the dealer counter, before the vehicle leaves the showroom.
- Applicant & guarantor: phone-to-ID matching → Thai ID Verification
- Faster forms: → KYC Fill-in
- At the dealer: → Location Verification
Payment gateways, PSPs & wallets
A PromptPay ID on a number that has been in service for 11 days behaves nothing like one on a number in service for six years.
- PromptPay enrolment & number change: → Thai ID Verification
- Pre-filter before costly checks: → Mobile Subscriber Status
- Step-up on risky transfers: → SIM Swap, Device Roaming
Why Infos
Both major networks, one Thai partner
Neither operator will sell you the other's coverage. We do, with a Thai-law contract and Thai-language support.
One contract
True-dtac and AIS under a single Thai-law agreement, with THB invoicing. No need to negotiate two enterprise deals.
One schema
One request and response format, whichever operator answers. Phone numbers in any Thai spelling.
We absorb API churn
Operator spec changes, encryption schemes and new error codes are our problem, not yours.
Evidence on every call
Every request and the operator's raw response are kept permanently: your audit trail and your dispute record.
Consent built in
A call without a consent reference is refused before it reaches any operator, and is never billed.
Thai team, Thai support
Bangkok-based engineers who speak your language and know the local operators.
Proof you took proactive measures
The Emergency Decree on Technology Crimes (No. 2) makes banks, telcos and platforms jointly liable for scam losses, apportioned by negligence. A recorded telco check at the moment of decision is evidence that you acted.
What we are
- An authentication and fraud-signal layer
- A real-time check at the moment of decision
- Documented evidence of compliance
✕What we are not
- An identity-proofing or e-KYC service
- A replacement for NDID, dip-chip or DOPA checks: we add a layer on top
- A cheaper SMS OTP: the value is fraud loss and liability
