FAQs – Frequently Asked Questions about UDIN

UDIN

What is a UDIN – Unique Document Identification Number for GST?

A UDIN or a Unique Document Identification Number is an 18-digit unique number which is generated by the system for every document which a practicing Chartered Accountant certifies or attests.

Why is a UDIN required?

A UDIN is needed by the law because it helps in avoiding frauds such as documents certified or attested by a random person. Such random persons may attest documents by posing as a CA hereby misleading stakeholders and authorities. A UDIN prevents such malpractices by securing documents which have been attested by actual and practicing CAs. This will ensure authenticity of documents for third parties.

What do the digits of a UDIN represent?

A UDIN has 18 alphanumeric digits which are arranged in the following manner:

The first two digits represent the last two digits of the current year (for year 2019, the digits will be “19”);

The next 6 digits represent the ICAI membership number of the CA (eg. 123456);

The last 10 digits represent the random alpha numerals generated by the system (eg. ABTSBN5678).

Therefore, a UDIN with the aforementioned details will look like: 19123456ABTSBN5678.

How secure is a UDIN?

A UDIN is extremely secure because it cannot be viewed by any third party. Only the member and the stakeholders/regulators that have the UDIN can view it.  Also, it is secure because a UDIN does not hold any of the client’s information.

When should a CA generate UDIN?

A UDIN should ideally be generated by the CA while attesting a document or certificate. A UDIN for GST can, however, be generated at any time within 15 days of attesting a document or certificate. These 15 days should be strictly counted from the date which is mentioned in the document.

Is any document upload or fee payment required in order to generate UDIN?

No, UDIN generation does not require any payment of fee or uploading of documents. Only those CAs who have a full-time Certificate of Practice can register on the UDIN portal so as to generate a UDIN. Only they can and should generate a UDIN.
