IREPS Login, Primary User Change & DSC Mapping: Complete 2026 Guide

Why IREPS Is Different

IREPS (Indian Railways E-Procurement System) at www.ireps.gov.in is OTP-gated and role-based. Unlike GePNIC (where any DSC can bid), every action on IREPS is tied to a Primary User and a mapped Class-3 DSC. Get either wrong and you see Primary User not mapped or DSC not registered — the two most common IREPS errors that block 60% of first-time bidders.

Key difference: GePNIC lets you bid with any valid DSC. IREPS requires the DSC to be mapped to the Primary User in the portal’s user management — a deliberate security layer for Railways.

Understanding IREPS Roles

• Primary User: The first user created during vendor registration. Only this user can map DSC, approve secondary users, and submit bids. Think of it as the admin of your vendor account.
• Secondary Users: Added by Primary User for tender search, document download, or bid preparation — but cannot submit without Primary User’s DSC.
• Vendor Code vs User ID: Vendor Code (VEN01234) is your firm’s ID (like a company PAN). User ID is your login (e.g., ven01234_p1). You search tenders with Vendor Code, but login with User ID + DSC.

Step 1 — Vendor Registration & Vendor Code

1. Go to www.ireps.gov.in → Vendor Registration (if you have a GePNIC vendor code, you can often reuse PAN/GSTIN, but IREPS still creates its own Vendor Code).
2. Enter PAN, GSTIN, firm type (Proprietorship/Partnership/Pvt Ltd), and address — IREPS validates via eprocure.gov.in and creates a Vendor Code (e.g., VEN01234). Write it down — you’ll need it to search tenders and track bids.
3. Verify email + mobile via OTP (both get OTPs, valid for 10 min).
4. Upload Gumasta/Shop Act + PAN card scan (max 2 MB, PDF).

Official resource: IREPS Vendor Manual — see “Vendor Registration” → “New Vendor Creation”.

Tip: Use Chrome + emSigner 2.6+ for registration — Firefox/Safari often fail at DSC mapping later.

Step 2 — Primary User Setup & Change

• The first user you create automatically becomes Primary User (has DSC rights + bid submit). You’ll see Role: Primary in My Account.
• To change Primary User (e.g., when the original person leaves): Login as current Primary → Administration → User Management → Change Primary User → select new user → OTP to both old and new user mobiles → approve with old Primary’s DSC PIN. The new user must then remap their DSC (Step 3).
• Only Primary User can: map DSC, approve secondary users, change vendor profile, submit bids. If you try these as Secondary, you’ll get Access Denied.

Step 3 — DSC Mapping (Class-3 Only, Signing + Encryption)

1. Plug your Class-3 DSC token (must have both signing and encryption certs — Class-2 will fail).
2. My Account → DSC Management → Map DSC → select Primary User from dropdown → enter OTP (sent to Primary’s mobile) + DSC PIN (usually 4-8 digits).
3. Test: DSC Management → DSC Mapping Status should show Active with your DSC serial. If Not mapped or Inactive, clear browser cache, restart emSigner (services.msc → emSigner → Restart), and retry with Chrome Incognito (IREPS prefers Chrome + emSigner, not Edge).

Why Class-3: Railways mandates Class-3 for all eProcurement since 2021 — Class-2 is rejected at mapping.

Step 4 — Bid Submission Checklist (Don’t Miss These)

• Login as Primary User with DSC plugged in before login (if you plug after, it won’t detect).
• Tenders → Search by Department/Date → Bid → download NIT + BOQ Excel + Corrigendum (if any) → fill BOQ offline (only yellow cells, save as .xls).
• Upload: Technical Bid (PDFs: GSTIN, PAN, Udyam, experience) → Financial Bid (BOQ) → EMD (online/BG as per NIT — IREPS shows EMD Status: Received before final submit, check it).
• Final Submit: DSC sign → Submit → save Acknowledgement with Bid Reference No. (e.g., IREPS/2026/12345) — you’ll need it to check Bid Status later.

Bid Bharat aggregates IREPS tender listings for search. IREPS bidding itself is OTP-gated and happens only on the official portal — always bid there.
