How to Set Up Federal Contract Bid Alerts by NAICS Code on SAM.gov
SAM.gov is where federal agencies post most contract opportunities above 25,000 dollars, and it can email you when new notices match your industry. The catch is that the alerts are only as good as the search you save behind them. This guide walks through setting up NAICS-based bid alerts on SAM.gov, the two notification types most suppliers confuse, and the gaps that leave teams scrambling on short-deadline solicitations.
Key takeaway
To get federal bid alerts on SAM.gov, sign in with a Login.gov account, filter the Contract Opportunities search by your NAICS code and set-aside type, then click Save Search and pick a daily or weekly email. You can also follow individual notices for immediate, daily, or weekly updates. SAM.gov alerts are free but cover only federal notices and match keywords literally, so many suppliers add a cross-source monitor to catch the rest.
| Notice type | What it signals | When to act |
|---|---|---|
| Sources Sought / Request for Information | The agency is researching the market and has not committed to buy | Respond early to shape requirements before the specification hardens |
| Presolicitation | A real solicitation is coming for a defined requirement | Get your capability statement and teaming ready now |
| Combined Synopsis / Solicitation | The live bid, with a firm response deadline | Read the evaluation criteria and decide bid or no-bid immediately |
| Special Notice | Industry day, pre-bid conference, or other event | Register to attend and ask questions on the record |
| Award Notice | The contract has been awarded to a vendor | Use it for competitor research and to time recompetes |
| Justification and Approval | A sole-source award the agency must publicly justify | Note the incumbent and the next likely competition window |
How federal bid alerts work on SAM.gov
Contract Opportunities is the part of SAM.gov where contracting officers publish solicitations. The search itself is open to anyone, but the alert features only appear once you sign in. Sign-in runs through a free Login.gov account with two-factor authentication, and you do not need to be a registered vendor with a Unique Entity ID just to save searches and receive emails. That means you can start tracking opportunities while your entity registration is still processing.
SAM.gov gives you two separate notification tools, and suppliers routinely mix them up. A saved search emails you when new or modified notices match a filtered query you built, for example a NAICS code plus a set-aside type. Following a notice tracks one specific opportunity and tells you when that single record changes, such as an amendment or a deadline extension. Most sellers want both: saved searches to discover new work, and follows to stay on top of bids they have already decided to pursue. For the vocabulary behind the filters, our SAM.gov glossary defines the terms you will meet along the way.

Set up a NAICS-based saved search alert, step by step
The whole point of a saved search is to turn a one-time query into a standing alert. Build the search tightly first, then save it. A loose query buries the few relevant notices under dozens that do not apply.
Step 1
Sign in with Login.gov
Go to sam.gov, select Sign In, and authenticate through Login.gov. The Save Search button only appears when you are logged in.
Step 2
Open Contract Opportunities
Choose the Contract Opportunities domain so your search and alerts cover solicitations rather than entities or assistance listings.
Step 3
Filter by NAICS code
Add your primary NAICS code, then layer on set-aside type, place of performance, and an active-only date filter to cut noise.
Step 4
Save the search and name it
Click Save Search and give it a clear label such as 541512 Small Business Set-Aside, so multiple alerts stay readable.
Step 5
Choose daily or weekly email
Set the alert frequency. Daily sends a morning summary of new and modified notices. Weekly suits low-volume codes.
Step 6
Repeat per code and review
Create one saved search per active NAICS code and target agency, then prune the ones that produce nothing useful.
Saved search alerts versus following a single notice
Knowing which tool to reach for saves you from missing either new work or a quiet amendment that changes the deal. The two mechanisms run on different schedules.
• Saved search alerts fire on a fixed cadence. You choose daily or weekly, and the email arrives as a morning digest of every new or modified notice that matched your filters since the last send. It is built for discovery across a whole category.
• Following a notice is per-opportunity. Open a solicitation you care about, select Follow, and set how often you want updates: immediately, daily, weekly, or none. Immediate follows are the safest choice once you have committed to a bid, because amendments and deadline changes can land with little warning.
A practical routine pairs the two. Use saved searches to surface candidates, run a quick bid or no-bid pass, then follow the survivors with immediate alerts. Teams that want this discovery layer to be faster and broader than a daily federal digest often add automated tender alerts on top of the native follows.

Choose the right NAICS codes, PSC codes, and set-asides
Your filters decide everything an alert can ever show you, so they deserve more thought than most sellers give them. Start with the NAICS code, which classifies your industry and drives small business size standards. Every opportunity carries one, and the Small Business Administration uses it to decide whether you count as small for a given solicitation. Pair it with the Product Service Code, which describes what is actually being bought rather than who sells it. Searching on both at once is sharper than either alone, because a single NAICS code can span very different deliverables.
Set-aside filters matter just as much for smaller firms. A large share of federal work is reserved for small businesses and specific categories such as 8(a), Women-Owned Small Business, Service-Disabled Veteran-Owned, and HUBZone. Filtering to the set-asides you qualify for strips out work you cannot win and makes the daily email worth reading. Our guide to small business federal contracting explains how to qualify for each, and the glossary entry on set-aside contracts covers the categories in plain language. Place of performance is the last useful filter when you only deliver in certain states. For the wider context on registration and codes, see the US government contracts guide and our overview of federal eProcurement systems.

Where SAM.gov's native alerts leave gaps
SAM.gov alerts are free, official, and worth setting up. They are also narrow in ways that cost suppliers real bids, so it helps to know the limits before you rely on them as your only feed.
There are smaller frictions too. Each saved search is its own email, so a seller with five codes manages five separate digests with no de-duplication when a notice matches more than one. There is no semantic understanding of synonyms, no scoring of how well a notice fits your business, and no single inbox that blends federal work with [[guides/state-local-government-contracts|state and local government contracts]]. None of this makes SAM.gov alerts bad. It makes them a federal-only, keyword-only baseline that most growing contractors eventually outgrow.
SAM.gov saved searches versus cross-source monitoring
Once a team is bidding regularly, the question stops being how to set up a saved search and becomes how to stop missing the notices a literal federal search cannot see. This is where a dedicated monitor earns its place alongside the native alerts.
| Capability | SAM.gov saved search | Jorpex |
|---|---|---|
| Sources covered | Federal Contract Opportunities only | 50+ portals including SAM.gov, state, and international |
| Matching | Literal keyword and code filters | Embedding-based semantic matching across synonyms |
| Timing | Once-daily or weekly morning email | Realtime, daily, or weekly digests |
| Delivery | Email only | Slack, Microsoft Teams, or email |
| Noise control | Manual per-search filters | Disqualifier filters and relevance scoring |
| Languages | English | 17 languages |
Jorpex monitors more than 50 public procurement sources and uses embedding-based semantic matching, so a notice for managed IT services still reaches a vendor who described their work as systems administration. You set your industries, NAICS focus, regions, contract value, and disqualifier filters once, then receive realtime, daily, or weekly digests in [[integrations/slack|Slack]], Microsoft Teams, or [[integrations/email|email]]. Plans start at 49 dollars per month for Starter and 149 for Pro, with a 14-day free trial. It does not replace your SAM.gov registration or your follows on specific notices. It sits above them as the discovery layer that catches what a literal federal search misses.

A federal alert routine that does not miss opportunities
Put together, a reliable setup has three layers. First, save tightly filtered NAICS searches on SAM.gov and read the daily digest, since it is the official source of truth for federal opportunities. Second, follow every notice you decide to pursue with immediate alerts so amendments never surprise you. Third, run a cross-source monitor for breadth and speed, because the contracts you do not yet know to search for are the ones a literal saved search will never show. Government contractors who win consistently treat alerting as a system, not a single email setting. If you are new to the market, start with the US government contracts guide, see how established firms use monitoring in our government contractors use case, and if you also chase state and county work, read about state and local bid notification before you rely on any one portal. The underlying discipline is the same one we describe in tender monitoring.
