Regulatory Verification & Title Audit · RERA Regulatory Specialist
A genuine RERA registration number follows a strict alphanumeric pattern determined by state regulatory authorities. Fraudulent marketing often exploits buyer confusion by displaying fake IDs, temporary acknowledgement numbers, or lapsed certificates. To safeguard your investment, verify the state-specific numbering syntax, ensure the prefix matches the official state code (e.g., UPRERAPRJ in UP, P5 in Maharashtra, PRM/KA/RERA in Karnataka), and never pay booking advances against an application tracking slip.
Explicitly bans advertising, marketing, booking, or selling real estate units without obtaining an official registration number from the state authority.
Prescribes penalties up to 10% of total estimated project cost and imprisonment up to three years for promoters marketing projects without valid RERA registration.
Imposes fines up to 5% of estimated project cost for providing false information or forged registration numbers to authorities or the public.

Financial Exposure of Booking on an Unregistered Project
Formula: Unprotected Capital = Total Advance Paid Outside Section 3 RERA Jurisdiction
Scenario: Buyer pays 10% advance (₹12,00,000) on a project advertised as "RERA Applied / In Process". If the authority subsequently rejects the registration due to disputed agricultural title, the builder account cannot be attached under Section 7.
Step-by-Step Verification Procedure
1Step 1: Check the State-Specific Alphanumeric Prefix
Every state has a designated prefix pattern. If the number on a marketing hoarding does not match the official pattern (e.g. MahaRERA numbers must start with P5, UP RERA with UPRERAPRJ), treat it as an immediate red flag.
- MahaRERA: P5XXXXXXXXXX (12 characters starting with P5)
- UP RERA: UPRERAPRJXXXXXX (Starts with UPRERAPRJ followed by project number and date)
- Karnataka: PRM/KA/RERA/... (Contains district and date codes)
2Step 2: Distinguish Acknowledgement Slip from Form C
Examine whether the number contains words like "ACK", "APP", "FILE", or "PENDING".
- If the document says "Application Acknowledgement", do not pay a single rupee.
- Demand a copy of "Form C - Registration Certificate" signed by the authority secretary.
3Step 3: Verify the Registration on the State Government Portal
Never trust a printed certificate provided by a broker. Always query the number independently on the official .gov.in state portal.
- Ensure the developer name on the portal matches the entity signing your sale agreement.
- Verify that the project status is "Approved / Registered" and not "Revoked" or "Lapsed".
4Step 4: Scan and Verify QR Codes
MahaRERA and several state authorities mandate that every real estate ad must feature a scannable QR code.
- Scan the QR code with your mobile camera.
- Verify that the URL opens an official state portal domain and displays the exact project report.
CRITICAL DIFFERENCE: A RERA Acknowledgement Number is merely an application receipt. It confirms only that documents were submitted to the government; it does NOT mean the project is legal or approved. A project is ONLY legal to purchase once Form C (Certificate of Registration) with a permanent registration number is issued.
Non-Negotiable Checkpoints Before Transferring Money
- ✓Alphanumeric code matches state prefix syntax perfectly.
- ✓Project status on official portal is "Registered / Active".
- ✓Builder corporate entity on RERA portal matches the seller on the agreement.
- ✓Form C certificate downloaded directly from government website.
- ✓Scanned QR code leads to genuine government registry URL.

Key Legal Clarifications & Homebuyer Inquiries
What does a sample RERA number look like?
Sample genuine RERA numbers include: P52100017324 (MahaRERA - Lodha Belmondo), UPRERAPRJ710087/09/2026 (UP RERA), PRM/KA/RERA/1251/310/PR/171015/000456 (Karnataka RERA), and HRERA-PKL-GGM-1082-2019 (Haryana HRERA).
What is a RERA acknowledgement number and can a builder sell using it?
A RERA acknowledgement number is a temporary tracking ID generated when an application is submitted online. Under Section 3 of RERA, a builder is legally prohibited from marketing, advertising, booking, or accepting money on an acknowledgement number. Doing so is an illegal offense under Section 59 punishable by fines up to 10% of total project cost.
How do I know if a RERA number is fake or forged?
A RERA number is likely fake if: (1) It does not match state syntax (e.g. lacks P5 in Maharashtra or UPRERAPRJ in UP), (2) Searching it on the state RERA portal returns "No Records Found", (3) The project name or developer name on the portal differs from the sales office, or (4) The QR code redirects to a private marketing page instead of a .gov.in domain.
What is the RERA number format for Uttar Pradesh (UP RERA)?
UP RERA numbers follow the syntax UPRERAPRJ followed by a 4 to 6 digit serial number, often appended with the month and year of original registration (e.g., UPRERAPRJ12345 or UPRERAPRJ710087/09/2026). Real estate agents have numbers starting with UPRERAAGT.
What is the RERA number format for Maharashtra (MahaRERA)?
MahaRERA numbers consist of 12 alphanumeric characters starting with "P5", followed by a 2-digit district code (e.g. 21 for Pune, 18 for Mumbai Suburban, 19 for Mumbai City, 20 for Thane), followed by an 8-digit unique serial number (e.g. P52100017324).
Where do I report a builder using a fake or misleading RERA number?
You can file a formal complaint under Section 59 directly on your state RERA portal under the "Non-Registration Complaint" or "Suo-Motu Complaint" section. You can also report misleading advertisements to the Advertising Standards Council of India (ASCI) and consumer courts.
