How to Become a UN Supplier and Reach the Real Buyer

To become a UN supplier, you need to do four things:

1. Register your company on the United Nations Global Marketplace (UNGM).
2. Start at Basic level.
3. Declare that you meet the UN's eligibility rules.
4. Choose the product codes that buyers search by.

For the UN Secretariat, Basic registration is mandatory before you can take part in a tender. Two higher levels cover bigger awards: Level 1 from USD 150,000 up to USD 500,000, and Level 2 above USD 500,000. Registration is free of charge.

That is the paperwork half. The other half is knowing who shapes the purchase. A program, an office or a field mission decides it needs something. A procurement team then runs a formal, competitive process to buy it. Suppliers who register and then wait are known to the second group and unknown to the first.

When a founder tells me they want a new market, I ask the same question every time: who already paid you, and who made the call on their side? The UN gets mapped like every other set of buyers, with the same method I use to pick a market before the first message goes out.

How much does the UN actually buy, and who is in scope?

The UN is many buyers sharing one portal.

The UN annual procurement report covers the whole UN system, and UNOPS puts it together. The 2025 report is its 42nd edition. Its 2025 highlights put UN procurement at $22.7 billion for the year, bought from suppliers in 227 countries and territories. The splits by organization and by country sit in that report's downloads and dashboards.

For a closer look at one buyer group, the UN Procurement Division's 2025 statistics show where its own spend went:

Two things in that table matter more to a supplier than the headline totals.

Headquarters and missions buy separately. A third of that ICT money was spent for missions, not headquarters. Same category, very different users. The person who needs a working network in a field mission sits in a different place from the one buying software for a headquarters department and has different worries.

The Secretariat is only part of the picture. UNGM also serves 22 agencies, funds and programs. Inside the Secretariat alone, a single registration reaches every Secretariat entity: headquarters, field missions, the regional economic commissions, the tribunals and the offices outside New York. Agencies, funds and programs then buy through their own procurement teams.

I would not start from this table, though. I start from the clients you already serve and look for buyers that resemble them.

Say you already work for construction or civil engineering contractors on public projects, industrial operators running remote sites, or IT teams in large institutions. Then a UN office is a close relative of someone who already pays you, and your proof will make sense to it. If you have never sold to an institutional buyer, the UN is a hard place to learn.

A useful test before taking on any new kind of client: will it bring you more of the people you want to work with three years from now, and would the tenth such client teach you anything the first did not? Run the UN through that filter before you spend a month on registration.

How do you become a UN supplier on UNGM?

The Secretariat runs vendor registration through UNGM. To start, you create an account, fill in the application and submit it.

The UN's help center calls UNGM a one-stop portal for 22 agencies, funds and programs plus the Secretariat. The higher levels add documents.

Every vendor starts at Basic, and moving up to a higher level is possible whenever you are ready. The UNGM glossary says a registered profile becomes visible to UN staff when they look for potential suppliers.

Before you click register, settle these:

• The level you will grow into. Plan the upgrade around the contract sizes you can really deliver this year.
• References. Ask three clients now, and get the letters in writing if you need Level 2.
• Accounts. Gather three years of accounts before you open the form.
• An owner for the profile. Name one person to read every UNGM notification.
• Your codes. Draft them before you start (more on that below).
• The declaration. Read the eligibility section with whoever signs legal documents for the company.

What documents and eligibility checks does the UN expect?

During registration you declare, for your company and the companies and people tied to it, that you meet the UN's prerequisites for eligibility:

• You are not under a UN procurement prohibition, including prohibitions that come from sanctions lists.
• You have not been removed or suspended by the UN or another UN agency.
• You are not under formal investigation, and no national authority of a UN Member State has sanctioned you for proscribed practices in the past three years.
• You have not declared bankruptcy, no bankruptcy or receivership case is open against you, and no court judgment or pending lawsuit stands against the company.
• You do not employ, and do not plan to employ, anyone who was UN staff within the last year if they dealt with your company in that UN role within the last three years.
• You will not engage in proscribed practices such as corruption, fraud, coercion or collusion, with the UN or anyone else.

You also commit to the UN Supplier Code of Conduct. The UN Procurement Division states a zero-tolerance policy on gifts. If any line above is untrue for your group today, fix it or get proper advice before you register. This is not legal advice.

Keep two gates apart in your head. Eligibility decides whether you can be considered at all. Awards are decided solicitation by solicitation, and the Secretariat's help center says it buys on best value for money.

A pre-submission check worth doing:

• Confirm the declaration with your owners and any subsidiaries, not only the operating company.
• Check your hiring plans for anyone who left the UN recently.
• Write a one-line gifts and hospitality rule for everyone who will talk to UN contacts.
• Agree who updates UNGM when anything in the company changes.

How do UN solicitations and requests for information work?

The UN says it buys through fair, transparent and competitive processes, and that every Secretariat opportunity is posted on its procurement website. Responses to requests for information now go through your UNGM login.

One definition from the UNGM glossary helps here. An invitation to bid is the format used when the requirement is clearly specified and the award goes to the lowest cost.

Being visible and being invited are not the same. Buyers search for vendors by UNSPSC product codes, and the help center asks you to keep those codes an accurate picture of your core goods and services. The Secretariat also considers only the first seven codes on your profile.

Choose codes that you actually win on, and put your strongest first.

A worked example. Say you make prefabricated site offices and accommodation units for remote projects.

1. Put the exact code for those units first, ahead of anything general like construction services.
2. Check posted opportunities every week for accommodation and site facility needs, especially from missions.
3. When one fits, answer through the channel the notice names. Lead with comparable deliveries to remote sites and your registration level.
4. If it is an invitation to bid, the specification is fixed and price decides. Only enter if you can meet the spec exactly at a sharp price.
5. If nothing fits this month, your profile still has to show up correctly the next time someone searches for your code.

Who really decides on UN contracts, the requisitioner or procurement officer?

Both, at different moments. The requisitioning office or mission defines the need: what, how much, by when, and to what standard. Procurement then runs the process to buy it under the rules. A supplier who only ever talks to procurement is talking to the people who run the process, and not to the ones who wrote the requirement.

On any past project, I look for who actually made the decision. Then I build lists from the real titles in that niche, never a vague "manager".

For UN buyers, the titles look like this:

Decision rules:

• No solicitation is live and you solve a problem someone feels: go to the buyer side. That means the program manager or chief of mission support, with a short note about a comparable result. Check that office's rules on vendor contact first, and never offer to help write a requirement.
• You need to know how an office buys: go to the procurement side. Ask about process, registration and where notices appear, and nothing more.
• A solicitation is live: stop all sales outreach about it, to either side. Every question goes through the channel the notice names.
• You cannot name the requisitioning office: you are not ready for outreach. Go back to the posted notices and the statistics until you can.

How can a supplier use outbound without crossing UN ethics rules?

I tell every founder the same thing: a buyer reviews your company before deciding, whatever your email says.

That holds even more inside an institution that has to justify every award. Assume the sale happens online, before the call, and that a UN office is no exception. So the proof has to sit inside the first message, not wait for a meeting.

I put the proof (past clients, real results, a case study) inside the message itself. For a UN buyer, put these in the note:

• one contract comparable in size and setting
• your UNGM registration level
• the code or category you are registered under

Write case studies a careful buyer can check, with a real outcome and timeframe. Keep the note short and human.

For the channel mix, see running LinkedIn and email as one follow-up sequence.

Where an office sits in Germany, Austria or the Czech Republic, I do not send cold email without a compliant basis; my team uses LinkedIn there instead. Anyone who asks not to be contacted goes on an exclusion list and stays there.

For timing, leave real time between follow-ups, then expect a long wait. B2B sales cycles often run 6, 9 or 12 months, and calls that happen in the first month can turn into deals four or more months later. We also recommend at least three months of outbound before judging it, because a campaign needs that long to collect feedback and improve.

The lines you never cross, from the eligibility section above:

• no gifts or hospitality
• no hiring or using recently departed UN staff to open doors
• no outreach about a tender while it is live

Anyone offering paid "access" or a faster registration is selling something the UN does not offer.

Whoever sends your outreach, the UN rules above apply in full.

What should you do in the first 30 days after you register?

Start with a business seminar. The UN Procurement Division runs business seminars for vendors and trade bodies, including chambers of commerce. They explain the procurement process, how vendor registration works and how to find opportunities. National governments, UN agencies and countries' Permanent Missions often help organize them. The listings can be filtered by country, so check whether your own chamber of commerce or trade body has one coming up.

A 30-day plan:

• Days 1 to 7: Submit Basic registration with your codes in priority order. Book a seat at the next relevant seminar.
• Days 8 to 14: Read the posted opportunities for your codes. Note which offices and missions publish them.
• Days 15 to 21: Map three to five offices that resemble clients you already serve. Find the program manager or chief of mission support in each.
• Days 22 to 30: Send proof-led notes to the buyer side where no solicitation is live, then follow up with real time between messages.

A first note you can adapt:

Hello [name], I saw that [office or mission] supports [operation or program]. We delivered [comparable contract, setting and result] for [type of buyer] in [year]. We are registered on UNGM at [level] under [category]. If [specific problem] is on your list for next year, happy to share a one-page summary of how that project ran.

There is no pitch and no meeting request in that note. Its only job is to put checkable proof in front of the person who feels the problem. It never suggests specifications, and the outreach stops the moment a solicitation goes live.

Registered with UNGM and unsure what comes next? You are welcome to book a call to talk through outreach that stays within UN rules.
