How do I get OEM authorisation to bid as a reseller on GeM?

Short answer
Ask the OEM for an authorisation letter written for the exact GeM bid you are bidding on: on the OEM's own letterhead, quoting the GeM bid number, naming your firm as the authorised bidder, and signed by an authorised OEM signatory. Upload it with your bid before the deadline. OEMs usually take 3–5 working days to issue one, so request it the day you shortlist the bid.
Key facts
- 42% of IT hardware and office supply tenders on GeM in Uttar Pradesh required a bid-specific OEM authorisation, based on our September 2026 scan of 3,450 tenders. The median tender value in that set was ₹12.5 lakh.
- A GeM bid can list "OEM Authorization Certificate" as a required document, alongside experience and past-performance documents (sample GeM bid document).
- On the portal, a reseller links to an OEM's brand through an authorisation code the OEM issues, entered in the Reseller Panel (GeM Seller FAQs). This is separate from the letter you upload in a bid.
- In OEM-controlled (CMS Q2) categories, only OEMs create catalogues; an authorised reseller sells by pairing with the OEM's catalogue (GeM Seller FAQs).
- OEMs typically take 3–5 working days to issue a bid-specific letter, in the requests our desk has handled.
What exactly is an OEM authorisation on GeM?
An OEM authorisation (the OEM Authorization Certificate, often called MAF) is the OEM's written confirmation that your firm may offer its product in a specific government bid. It tells the buyer the product you quote is genuine, will be supported by the manufacturer, and is being offered with the manufacturer's consent.
For a reseller, there are two layers of authorisation, and people confuse them all the time:
- Portal-level authorisation (Reseller Panel). The OEM creates an authorisation code for you in its OEM Panel. You enter that code in My Account → Reseller Panel, choosing the category and brand. Once approved, you can pair with the OEM's catalogue and sell its listed products (GeM Seller FAQs).
- Bid-level authorisation (the letter). When a buyer's bid asks for an OEM Authorization Certificate, you upload a letter from the OEM for that bid. Portal-level pairing does not replace this letter.
If a bid asks for the letter and you have only the portal pairing, your bid is incomplete.
Generic distributor certificate vs bid-specific authorisation: what is the difference?
A generic distributor or dealer certificate says you are an authorised seller of the brand. A bid-specific authorisation says you are authorised for this bid. When the bid asks for the second, the first will not pass.
| Generic dealer / distributor certificate | Bid-specific OEM authorisation | |
|---|---|---|
| What it proves | You are an authorised channel partner of the brand | The OEM backs your offer in this bid |
| Mentions the GeM bid number | No | Yes, the exact bid number |
| Validity | Usually a year or an open period | Tied to the bid, often through contract and warranty |
| Reusable across bids | Yes | No, a fresh one for each bid |
| When it is enough | When the bid only asks for proof of dealership | Whenever the bid's terms ask for a bid-specific letter |
How to tell which one a bid wants: read the bid document and its Additional Terms and Conditions (ATC). If the wording asks for authorisation "for this bid" or asks you to quote the bid number, treat it as bid-specific.
How do I apply for a bid-specific OEM authorisation? Step by step
- Shortlist the bid and read the document list. Who: you. Documents: bid document and ATC. Time: same day. Confirm "OEM Authorization Certificate" or similar wording appears, and note the exact bid number, item, quantity and closing date.
- Check your portal-level standing with the OEM. Who: you. Documents: your GeM Reseller Panel status. Time: same day. In an OEM-controlled category, confirm you are an approved reseller for that brand and category; if not, ask the OEM for an authorisation code first.
- Send the OEM a written request. Who: you, to the OEM's channel or tender team. Documents: your GSTIN, Udyam (if any), GeM seller ID, the bid number, product model and quantity, and the buyer's name. Time: day 1. Put the bid number in the subject line and ask for the letter on OEM letterhead, addressed to the buyer, quoting the bid number.
- Share what the letter must say. Who: you. Documents: a checklist taken from the bid document. Time: day 1. Your firm's legal name as on GeM, the bid number, the product and model, any warranty or support commitment the bid asks for, and the signatory's name and designation.
- Receive and check the letter line by line. Who: you. Documents: the OEM letter. Time: day 3–5. Match the bid number character by character, your firm name against your GeM profile, and the model against your offer. Ask for a corrected letter before you upload, not after.
- Upload it with your bid. Who: you. Documents: the signed letter (PDF). Time: before the closing date. Upload it in the document slot the bid specifies, with a file name that includes the bid number.
- Keep a copy with the bid record. Who: you. Documents: the letter and your request email. Time: after submission. You may need it at technical evaluation or if the buyer raises a clarification.
Timing rule: with a 3–5 day OEM turnaround, a bid that closes in under a week leaves almost no room to fix a mistake. Start the request the day you shortlist.
From our desk
Case: an ₹18 lakh server tender lost on one document. A networking equipment reseller from Kanpur had quoted the lowest price (L1) on an ₹18 lakh server tender. The bid's ATC strictly demanded a bid-specific OEM authorisation, but the reseller had not read the ATC and uploaded their generic one-year distributor certificate instead. The bid was disqualified at technical evaluation. Had they requested a bid-matched letter from the OEM three days earlier, their bid would have gone on to price evaluation with the lowest quote.
The generic certificate trap. This is the most common failure we see. The reseller is a genuine dealer and the product is right, but the document does not answer what the bid asked, so the bid fails before price is even compared.
The bid-number mismatch. The second pattern is a letter that is bid-specific but quotes the wrong number — reused from an earlier bid, or a digit mistyped by the OEM's team. It looks correct at a glance, which is why it slips through. We now check the number on every letter against the bid page before anything is uploaded.
What our tender data shows
- 42% of UP IT hardware and office supply bids required a bid-specific authorisation (GeM, September 2026 scan of 3,450 tenders). For a reseller in these categories, a bid-specific letter is close to a coin-flip requirement, not an edge case.
- The median tender value was ₹12.5 lakh. At that size, losing a bid over one document is an expensive mistake — and a 3–5 day OEM request is worth planning for.
Common mistakes that get GeM bids rejected over authorisation
| Mistake | What happens | Fix |
|---|---|---|
| Uploading a generic dealer certificate when the bid asks for bid-specific authorisation | Fails technical evaluation | Read the ATC; request a letter quoting the bid number |
| Wrong or old bid number on the letter | Document does not match the bid; likely rejection | Check the number character by character before upload |
| Letter not on OEM letterhead, or unsigned | Authenticity can be questioned | Ask for signed letterhead with signatory name and designation |
| Firm name on letter differs from GeM profile | Buyer cannot link the letter to you | Give the OEM your exact legal name as on GeM |
| Model on letter differs from model offered | Mismatch at evaluation | Quote the exact model and part number in your request |
| Requesting the letter too late | Letter arrives after the bid closes | Request on the day you shortlist; plan for 3–5 days |
| Relying only on Reseller Panel pairing | Required document missing from the bid | Pairing lets you sell on the portal; the bid letter is separate |

FAQ
Do I need OEM authorisation for every GeM bid?
No. You need it when the bid document or its ATC asks for an OEM Authorization Certificate. In our September 2026 scan of 3,450 UP IT hardware and office supply bids, 42% did.
Can I reuse one OEM authorisation letter for several bids?
Not when the bid asks for a bid-specific letter — that letter quotes one bid number, so each bid needs its own. A generic dealer certificate can be reused, but it only works when the bid does not demand bid-specific authorisation.
How long does an OEM take to issue a bid-specific authorisation?
In the requests our desk has handled, OEMs usually take 3–5 working days. Request it the day you shortlist the bid, not in its last week.
What is the difference between the GeM Reseller Panel authorisation code and an OEM authorisation letter?
The authorisation code links you to the OEM's brand on the GeM portal so you can pair with its catalogue. The letter is a document for one bid. A bid that asks for the letter still needs the letter, even if you are paired.
Who should sign the OEM authorisation letter?
An authorised signatory of the OEM, on the OEM's official letterhead, with name and designation. If the bid specifies more — a seal, or particular contact details — follow the bid.
