RBI CMS Portal: File & Track Complaintscms.rbi.org.in in 5 steps
The RBI complaint portal for banks, NBFCs and fintechs — filing flow, 10 MB upload rules, and how status tracking really works.
Quick Answer
The RBI CMS portal at cms.rbi.org.in is a single online window to complain against any RBI-regulated bank, NBFC or fintech. Launched June 2019, it needs a 30-day pre-step with the lender, accepts up to 10 MB of evidence, and issues a Complaint Registration Number by SMS and email for real-time tracking.
No 30-day lender pre-step = auto-rejection
Clause 10(1) of RB-IOS 2026 makes the pre-step mandatory. CMS complaints filed without it are rejected as 'Not Maintainable' by the CRPC Chandigarh — you have to start over.
⚖️ What is the RBI CMS portal (cms.rbi.org.in)
The RBI Complaint Management System is a single web-based platform hosted at cms.rbi.org.in. It lets any customer file, upload evidence, and track grievances against every RBI-regulated entity — banks, NBFCs, ARCs, credit information companies and payment system operators. Before June 2019 the same journey needed separate emails to different Ombudsman offices.
“The Reserve Bank of India today launched the Complaint Management System (CMS), a software application to facilitate RBI's grievance redressal processes. Members of the public can now access the CMS on RBI's website to lodge their complaints against any of the entities regulated by RBI.”
What CMS is designed to cover
- Deficient banking service, wrong charges, mis-selling and mule-account disputes.
- NBFC and digital-lender grievances — recovery harassment, hidden charges, KFS mismatch.
- Credit Information Company disputes — wrong CIBIL / Experian reporting.
- Payment system disputes — UPI, PPI wallet, prepaid card, mobile banking failures.
📄 How to file a complaint on the RBI CMS portal (step-by-step)
The filing flow follows five procedural stages baked into the portal. Miss any one and the CRPC Chandigarh routes the case straight to ‘Non-maintainable’. Follow them in order and the acknowledgement usually arrives within minutes.
- 1Step 1
Complete the mandatory 30-day pre-step
Send a written complaint to the bank or NBFC first. Wait for an unsatisfactory reply or 30 days of silence.
Skip = auto reject - 2Step 2
Open cms.rbi.org.in and pick the entity
Click 'File a Complaint'. Select category — Bank / NBFC / System Participant / CIC — then the specific entity.
Entity picker - 3Step 3
Verify with mobile OTP
Registered mobile receives a one-time password. The number becomes your permanent login handle for status tracking.
OTP login - 4Step 4
Fill details and upload evidence (10 MB max)
Personal, contact, transaction and relief-sought fields. Upload the pre-step complaint, reply, KYC and proof documents.
10 MB cap - 5Step 5
Submit and save your Complaint Registration Number
You get an SMS and email with a unique CRN. Save it — you will need it every time you log back in to track status.
CRN issued
“The complainant must (i) select the regulated entity, (ii) confirm that a complaint was already made to the entity and 30 days have passed or a reply was received, (iii) fill in personal and transaction details, (iv) upload supporting documents up to a total size of 10 MB across PDF, JPG, JPEG, PNG or Word formats, and (v) submit to obtain a unique Complaint Registration Number.”
TARA drafts your CMS complaint end-to-end
Auto-fills the entity picker, pastes your grievance in RBI's preferred format, and assembles the 10 MB evidence bundle in one click.
🔐 CMS portal login and OTP verification flow
Every action on cms.rbi.org.in — filing, tracking, appeals — is gated by a mobile OTP. There is no username or password. Your registered mobile number is the single identifier that ties every session to your Complaint Registration Number.
Use one mobile only
Pick the mobile that is registered with the bank or NBFC. Reusing a family member's number breaks the identity trail.
OTP is valid 3 minutes
The CMS OTP expires in three minutes. Refresh and re-request if you miss the window — no lockouts on retry.
Save the CRN on paper
Screenshots get lost. Write the Complaint Registration Number in a notebook the moment SMS arrives.
Whitelist RBI email
Add donotreply@rbi.org.in to your address book. Status updates land there, sometimes ahead of the SMS.
The biggest OTP-flow mistake
File the complaint from a friend's mobile because your phone is not around.
Wait until you have the registered mobile in hand. The CRN and every status update will only ever go to that number.
📊 Track complaint status on rbi.org.in complaint portal
Every CMS complaint moves through six named stages. You can watch the transitions live by logging into cms.rbi.org.in with your CRN and registered mobile. The portal is mobile-responsive, so tracking works from any phone browser.
| Status stage | What it means | Action for you | Typical timeline |
|---|---|---|---|
| Received | CRPC Chandigarh has logged the complaint | Wait — no action needed | Day 0 to 3 |
| Under Process | Routed to Ombudsman office with jurisdiction | Keep evidence ready | Day 3 to 21 |
| Additional Info Sought | Ombudsman wants clarification / more docs | Reply within the deadline in the notice | Any time |
| Closed — Resolved | Grievance settled between you and the entity | Confirm resolution | Day 30 to 90 |
| Closed — Not Maintainable | Case fails RB-IOS eligibility (usually pre-step) | Fix defect and refile | Day 3 to 15 |
| Award Issued | Ombudsman has passed a binding Award | Send acceptance letter within 30 days | Day 60 to 120 |
“The status of a complaint filed on the CMS moves through the stages Received, Under Process, Additional Information Sought, Closed — Resolved, Closed — Not Maintainable and Award Issued. Complainants can track their complaint in real time using the Complaint Registration Number and the registered mobile.”
Paste your CRN — TARA reads your CMS status live
TARA pulls the current status stage, flags whether the Ombudsman is waiting on you, and drafts the next reply if 'Additional Info Sought' has been raised.
📞 RBI complaint management system: acknowledgement & timelines
After submit, CMS auto-routes each complaint. The Centralised Receipt and Processing Centre at Chandigarh handles scrutiny; jurisdictional Ombudsman offices handle the merits. Acknowledgement lands as SMS and email inside minutes.
“The Reserve Bank has operationalised a Centralised Receipt and Processing Centre (CRPC) at Chandigarh for the receipt and initial processing of physical and email complaints in any language. Complaints filed on the CMS are auto-routed based on jurisdiction and nature of the grievance.”
“No complaint for deficiency in service shall lie unless it is made within one year after the complainant has received the reply of the Regulated Entity to the representation or, where no reply is received, within one year and thirty days from the date of representation.”
🔍 RBI grievance portal vs banking ombudsman portal (routing rules)
Users often ask whether they should file at ‘the banking ombudsman portal’ or the RBI grievance portal. Both are the same system since November 2021 — RB-IOS 2026 collapsed the three earlier schemes into one CMS window at cms.rbi.org.in.
| Old route (pre-2021) | What replaced it | Where you go today | Common misconception |
|---|---|---|---|
| Banking Ombudsman Scheme | RB-IOS 2026 | cms.rbi.org.in | That there is a separate BOS portal — there is not |
| NBFC Ombudsman Scheme | RB-IOS 2026 | cms.rbi.org.in | That NBFC complaints go by post — they do not |
| Digital Transactions Ombudsman | RB-IOS 2026 | cms.rbi.org.in | That UPI disputes need a separate window — they do not |
| Physical / postal complaints | CRPC Chandigarh | CRPC scans and uploads to CMS | That paper filings bypass CMS — CRPC digitises them |
RBI CMS complaint portal against bank / NBFC / fintech
- Bank complaints — pick category Bank, then the exact branch entity name.
- NBFC and digital lender — pick category NBFC, use the Certificate of Registration name (not brand).
- Fintech app — file against the sponsoring NBFC / bank, not the app brand (RBI regulates the NBFC).
- Credit bureau errors — pick Credit Information Company, name CIBIL / Experian / Equifax / CRIF as applicable.
🛡️ Common CMS portal errors & fixes
Nine out of ten CMS rejections trace back to five recurring errors. Every one is fixable before you hit submit if you know what CRPC is scanning for. The portal itself is stable; the eligibility gate is where most complaints die.
Filed too early
Under 30 days from lender complaint with no reply — refile after day 30.
Upload over 10 MB
Compress PDFs, drop duplicate photos. Stay under the 10 MB hard cap.
Wrong entity category
Fintech app filed as Bank — pick the sponsoring NBFC or Bank, not the app brand.
Filed after 1 year
Clause 10(2) window closed. Only rare condonation via written reasons to the Ombudsman.
The single biggest CMS filing mistake
Upload a screenshot of only the WhatsApp reply from the recovery agent as your evidence.
Attach the formal email or letter you sent the bank, the bank's written reply (or proof of 30-day silence), plus the harassment evidence — in one bundle under 10 MB.
🗣️ Real Cases: CMS Portal Wins
“A digital lender charged Rs 4,200 in processing fees that were never in the sanction letter. I sent the bank a written complaint, waited 30 days, then filed on cms.rbi.org.in with the KFS mismatch highlighted. Refund landed in 42 days.”
“Recovery agent called at 10 PM three nights in a row after the FPC window. TARA helped me file at CMS with the call-log PDF under 6 MB. Ombudsman issued an Award of Rs 15,000 compensation for harassment.”
“My CIBIL still showed a closed loan as active six months after the No-Dues Certificate. Filed CMS against the CIC, uploaded the NDC and the credit report. Report was corrected within 21 days and my score jumped 62 points.”
