Understanding the service
This service coordinates verification of an existing UDIN and the related document. A UDIN can only be generated by the authorised professional; ACS does not sell issuance.
Start from the actual document
Obtain the document and its stated UDIN through an appropriate channel. Use the official verification route and compare the available details with the document presented. A reference number typed into a message is not a substitute for reviewing the relevant document.
Understand the limit of the check
Verification helps check the recorded reference; it does not independently audit the financial information or guarantee acceptance by a bank or authority. Issuance belongs to the eligible professional. ACS offers verification coordination, not the sale or generation of a UDIN.
Preparation checklist
Use this as a starting file, not a universal eligibility decision. ACS confirms the final checklist against your actual entity, activity and reporting period.
- Applicant or entity identification
- Existing registration records, if applicable
- Address and authorised signatory details
- Service-specific documents confirmed after review
Keep originals and final versions distinguishable. Record missing information before submission and use the agreed private channel for sensitive evidence.
From enquiry to agreed work
- Share the requirement and relevant reporting period.
- ACS reviews the records and confirms the scope and charges.
- Preparation, review and authorised filing or delivery.
- Receive completion records and the next-step checklist.
Better assurance that the document reference can be checked through the appropriate route. Timing depends on the supplied records, applicable process and external review. No authority decision or processing date is guaranteed.
ACS professional fee
Government fees, taxes, provider charges and additional professional work are separate unless the written quote says otherwise. The listed fee is not a grant, tax, contribution or licence payment. Online payments remain inactive.
Frequently asked questions
Can ACS create a UDIN for any document?
No. Only the eligible authorised professional can generate it under the applicable ICAI requirements.
Does successful verification prove every figure is correct?
No. It is not an independent opinion on the underlying financial statements or transactions.
What does the listed professional fee include?
The ACS fee covers only the work confirmed in your quote. Government fees, taxes, provider or certification-body charges and additional professional work are separate unless expressly included. Booking does not activate an online payment.
What should I share for the first discussion?
Start with your requirement and the relevant period or project. The callback form needs only your name and mobile number. Share identity, banking or financial documents only through the agreed private workflow.
