What the ICAI membership number actually is
Every chartered accountant in India holds a membership number issued by the Institute of Chartered Accountants of India (ICAI). That number is the single identifier that ties a person to the profession. It is also the one thing you can check yourself, in minutes, without asking anyone's permission.
On Attesar, the registration number shown on a professional's profile is self-declared. Attesar verifies identity; it does not check the number against the ICAI register. That check is yours to make, and it is straightforward. If you are comparing profiles under Chartered Accountants, treat the number as a claim to be tested, not a fact already confirmed.
Where the record lives
The ICAI maintains its own register of members. This is the authoritative source. A firm's website, a directory listing, a letterhead or a marketplace profile are all secondary — useful for finding the number, useless for confirming it.
Search the ICAI register using the membership number. If you only have a name, search by name and then cross-check the number that comes back. The register entry tells you whether the person is a current member and what that membership consists of.
What the number tells you
- That the person is, or was, a member of ICAI.
- The membership category, which distinguishes a chartered accountant from a non-member.
- Whether the membership is current.
What it does not tell you
- Whether the person is any good at the work you need done.
- Whether they have capacity for a new client.
- Whether they hold a certificate of practice, which is a separate matter from membership.
- Whether the specialisations listed on a profile — statutory audit, GST audit, business valuation — are things they actually do day to day.
Reading the letters after the name
Profiles list qualifications in shorthand. The shorthand matters, but only up to a point.
CA, ACA, FCA are membership designations. ACA and FCA reflect standing within the institute rather than a different licence to practise.
DISA is a post-qualification diploma in information systems audit. It signals a specialism, not a separate registration.
B.Com, M.Com are university degrees. They are not accountancy qualifications in the regulatory sense, and a profile carrying them without CA, ACA or FCA is not a chartered accountant profile.
A number and a designation together are the minimum. Neither substitutes for the other.
Matching the number to the work you need
Chartered accountants cover a wide field. The register confirms membership; it does not sort members by service. You have to do that part by reading what the profile says and asking direct questions.
| Area of practice | Typical work |
|---|---|
| Taxation | Income tax filing, tax planning, TDS compliance, assessments and scrutiny |
| GST | GST registration, GST returns, GST audit, refunds |
| Audit & Assurance | Statutory audit, internal audit, tax audit, stock audit |
| Company Compliance | ROC filings, incorporation, annual returns |
| Advisory | Business valuation, due diligence, project finance |
| Accounting | Bookkeeping and financial reporting |
If you are searching for a chartered accountant near me because you need GST returns filed monthly, the register check is the same as it would be for a statutory audit — but the conversation afterwards is different. Ask what software they use, who handles the filing, and what happens when a notice arrives.
A checklist before you engage anyone
- Take the membership number from the profile.
- Search it on the ICAI register.
- Confirm the name matches the profile name.
- Confirm the membership is current.
- Check whether the specialisation you need appears in the profile's stated areas of practice.
- Ask directly which of those areas the person handles personally.
- Ask for the scope of work and the fee in writing.
Steps 1 to 4 take minutes. Steps 5 to 7 take a conversation, and they are where most of the risk sits.
When something does not match
The name on the register differs from the name on the profile. The number returns no result. The membership has lapsed. The profile claims FCA but the register shows otherwise.
Any of these is a reason to stop and ask. Sometimes there is an innocent explanation — a name change, a transcription error, a number typed with a digit transposed. Sometimes there is not.
Do not proceed on an assurance that it will be sorted out later. Ask for the correct number and check it again. If the person cannot or will not supply a number that matches the register, treat the profile as unverified regardless of what it displays, and look elsewhere. A chartered accountant barred from advertising or soliciting work cannot chase you for the business, and will not be offended by a polite request to confirm a number.
Why the CA for GST and tax filing queries need this check most
Tax filing and GST work run on deadlines. Returns, TDS deposits, refund applications and assessment responses all have dates attached, and a missed date carries consequences that are difficult and sometimes impossible to undo.
That is exactly why the register check matters for these engagements. An audit firm or a tax filing CA handling your compliance has access to your financial detail and speaks to the department on your behalf. The membership number is the one objective thing you can verify before handing any of that over.
It is not a guarantee. It is a filter, and a cheap one. Use it before you use anything else.
