LinkedIn Company ID: definition and core principles

The LinkedIn Company ID (also called Organization ID or Company Identifier) is a unique numeric identifier assigned by LinkedIn to each company page on the platform. It’s a string of digits, typically between 5 and 9 characters, that permanently identifies an organization on LinkedIn.

Unlike customizable vanity URLs (like linkedin.com/company/derrick-app), the Company ID is immutable: once assigned, it never changes, even if the company modifies its name or custom URL.

LinkedIn Company ID format:

linkedin.com/company/1234567
                      ↑
                  Company ID

Real examples:

• LinkedIn (the company itself): Company ID 1337
• Microsoft: Company ID 1035
• HubSpot: Company ID 42367

When a company creates its LinkedIn page, it automatically receives this identifier. This serves as an internal reference for all interactions with the LinkedIn API and third-party tools that connect to it.

For an SDR or Growth Marketer prospecting daily, understanding and using Company IDs saves considerable time by automating repetitive tasks. Instead of manually searching for each company, you can build structured lists, extract data in bulk, and systematically enrich your CRM.

Why the LinkedIn Company ID is crucial for B2B prospecting

According to Sopro (2026), 53% of B2B marketers use LinkedIn to identify prospects and collect their contact details. LinkedIn generates 80% of all B2B leads from social media, far surpassing Facebook, X, or Instagram. With 1.2+ billion members worldwide (Sprout Social, 2026), LinkedIn has become the essential hunting ground for professional prospecting.

But how do you transform this mass of data into concrete business opportunities? That’s where the LinkedIn Company ID comes in.

Integrations with ATS and CRM systems

Applicant Tracking Systems (ATS) like Greenhouse, Lever, JazzHR, or Trakstar require your Company ID to automatically publish your job postings on LinkedIn and associate them with your company page. Without this identifier, your ads appear generically, reducing their visibility and credibility.

Similarly, CRMs like HubSpot, Salesforce, or Pipedrive use the Company ID to automatically enrich your accounts with LinkedIn data: number of employees, industry, recent growth, technologies used. For a Sales Ops Manager handling a pipeline of hundreds of accounts, this automation saves hours every week.

Prospecting automation at scale

LinkedIn automation tools — PhantomBuster, Evaboot, La Growth Machine, or Derrick — rely on the Company ID to:

• Extract all employees from a targeted company: Looking for all Heads of Sales in 50-200 employee SaaS companies? The Company ID allows precise filtering.
• Create conditional workflows: “If the company raised funds recently, send a personalized message.”
• Sync lists between tools: Export a Sales Navigator search to your CRM, then to your email sequence.

Sarah, Head of Sales at an EdTech startup, uses this approach to identify decision-makers in 200 target companies. She exports Company IDs from Sales Navigator, enriches them with firmographic data, then launches personalized outreach sequences. Result: 40% acceptance rate on LinkedIn and 12% meetings booked, compared to 18% and 4% with manual prospecting.

Account-Based Marketing (ABM)

ABM involves concentrating your marketing efforts on a limited number of high-value accounts. The Company ID is central to this strategy: it allows you to create ultra-targeted advertising audiences on LinkedIn Ads, track engagement for each target account, and coordinate your sales and marketing actions.

Mike, a Growth Marketer at a B2B agency, targets 50 enterprise companies. He uses Company IDs to run LinkedIn Ads only to employees of these companies, track which pages they visit on his site, and alert his sales team when an account shows interest signals. In 3 months, 8 target accounts booked a demo, compared to 2-3 previously with a generic approach.

Now that you understand why the Company ID is strategic, let’s see concretely how to find it.

How to find the LinkedIn Company ID: 4 simple methods

There are several ways to retrieve a company’s LinkedIn Company ID. Some methods are faster, others more reliable depending on your context. Here are the 4 main methods, from simplest to most advanced.

Method 1: Directly from the company page URL

This is the fastest method if the company page uses a numeric Company ID in its URL.

Steps:

1. Go to LinkedIn and type the company name in the search bar.
2. Click on the corresponding company page.
3. Look at the URL in your browser’s address bar.

URL format:

https://www.linkedin.com/company/1234567/
                                ↑
                            Company ID

Expected result: You immediately see the Company ID. Just copy this number.

Real example:

• For Microsoft: https://www.linkedin.com/company/1035/ → Company ID = 1035
• For Salesforce: https://www.linkedin.com/company/3185/ → Company ID = 3185

⚠️ Limitation of this method: Some companies use a custom vanity URL instead of the number. For example:

https://www.linkedin.com/company/derrick-app/

In this case, the Company ID doesn’t appear directly. You need to use Method 2 or 3.

Method 2: Via the “See all employees” section

This method works even if the company uses a vanity URL.

Steps:

1. Go to the company’s LinkedIn page.
2. Scroll down to the “People” or “Employees” section.
3. Click on the “See all [X] employees” link.
4. A new page opens with the employee list. Look at the URL in the address bar.

URL format:

https://www.linkedin.com/company/derrick-app/people/?...&currentCompany=%5B%2212345678%22%5D&...
                                                                              ↑
                                                                         Company ID

The Company ID is the string of digits between the %22 codes (encoded quotes). In this example: 12345678.

Browser variations:

• Chrome: The Company ID is between the quotes "12345678" in the URL.
• Other browsers (Firefox, Safari): It may be between percentage signs %22.

Expected result: You get the Company ID even if the page uses a vanity URL.

Tip: To confirm it’s the correct ID, open a new tab and type:

https://www.linkedin.com/company/12345678/

If you’re redirected to the correct company page, it’s the right Company ID.

Method 3: Via the “See all jobs” section

An alternative to Method 2 that works if the company has published job postings on LinkedIn.

Steps:

1. Go to the company’s LinkedIn page.
2. Scroll down to the “Jobs” section.
3. Click on “See all jobs”.
4. A new page opens. Look at the URL in the address bar.

URL format:

https://www.linkedin.com/jobs/search/?f_C=1234567&...
                                         ↑
                                     Company ID

The Company ID is the value after f_C=. In this example: 1234567.

Expected result: You retrieve the Company ID in seconds.

This method is particularly useful for recruiters or staffing agencies targeting actively hiring companies.

Method 4: If you’re a company page admin

If you manage your company’s LinkedIn page, you have privileged access to the Company ID.

Steps:

1. Log in to your LinkedIn account.
2. Go to the “Pages” or “All Pages” menu.
3. Select your company page.
4. Click on “Admin view” or the “Home” tab.
5. Look at the URL in the address bar.

URL format:

https://www.linkedin.com/company/8681905/admin/
                                ↑
                            Company ID

Expected result: You immediately see your Company ID. Note it for use in your ATS, CRM, or automation tool integrations.

This method is the most reliable for companies wanting to distribute their Company ID internally (HR team, sales, marketing) to ensure integration consistency.

You now have four methods to find any LinkedIn Company ID. But how do you actually leverage this identifier in your daily prospecting? Let’s look at concrete applications.

How to use the Company ID in your prospecting workflows

Finding the Company ID is just the first step. The real power lies in its strategic use to automate and optimize your B2B prospecting.

Target specific companies in Sales Navigator

LinkedIn Sales Navigator is the reference tool for advanced B2B prospecting. Over 700,000 sales professionals use it to find qualified prospects, and 78% of salespeople doing social selling outperform their peers (LinkedIn statistics 2026).

The Company ID allows you to filter your Sales Navigator searches with surgical precision.

Concrete workflow:

1. Identify your 50 target accounts and retrieve their Company IDs (via the methods above).
2. In Sales Navigator, use the “Company” filter and enter the Company IDs one by one, or create a saved company list.
3. Add additional filters: job title (e.g., “Head of Sales”), seniority (Director, VP), geography, etc.
4. Export the prospect list and launch your outreach sequence.

Example persona:

Emma, an SDR at a SaaS company selling to e-commerce, targets Shopify sites that have raised funding. She extracts Company IDs from 100 e-commerce companies via a Crunchbase list, imports them into Sales Navigator, filters for “CMO” or “Head of Growth,” and gets 287 ultra-qualified prospects in 10 minutes instead of several hours of manual searching.

Extract employee lists for cold outreach

Once you’ve identified a target company, you often want to contact multiple people within that organization: the CMO, Head of Sales, VP Marketing, etc. The Company ID facilitates this bulk extraction.

Tools that leverage the Company ID:

• PhantomBuster: Scrapes all employees from a given company.
• Evaboot: Extracts leads from Sales Navigator using the Company ID as a filter.
• Derrick: Automatically enriches your lists with emails, phone numbers, and other attributes from the Company ID.

Concrete workflow:

1. Identify 20 B2B SaaS companies with 50-200 employees using Salesforce as their CRM (via a technographic data tool).
2. Retrieve the 20 Company IDs.
3. Use a LinkedIn scraper to extract all profiles from these companies with titles containing “Sales,” “Marketing,” or “Growth.”
4. Enrich the list with verified emails and phone numbers via Derrick.
5. Import into your cold emailing tool and launch your campaign.

Expected result: David, a Growth Marketer at a lead gen agency, goes from 3 hours per day searching for prospects to 30 minutes per week with this approach. He generates 150 new qualified leads every week, compared to 40 previously.

Integrate LinkedIn with your tech stack

The Company ID also serves as a bridge between LinkedIn and your other tools: CRM, marketing automation, data warehouse, etc.

Integration examples:

• HubSpot: Create custom properties to store Company IDs for your target accounts, then trigger automatic workflows (e.g., “If Company ID exists, enrich with LinkedIn data via API”).
• Zapier / Make / n8n: Build automations that trigger as soon as a new Company ID is added to your CRM. For example: automatically create a Slack alert with the company’s latest news.
• Salesforce: Use the Company ID to deduplicate your accounts and ensure the same LinkedIn account isn’t created multiple times under slightly different names.

Jessica, Sales Ops Manager at a scaling SaaS company, set up a workflow that automatically syncs Company IDs from Derrick to HubSpot, then triggers complete enrichment of each account with firmographic and technographic data. Result: 92% of accounts in her CRM now have complete data, compared to 48% before this automation.

Common mistakes with LinkedIn Company ID (and how to avoid them)

Even with the best intentions, it’s easy to make mistakes when using Company IDs. Here are the most frequent pitfalls and how to avoid them.

Mistake 1: Confusing Company ID and vanity URL

Symptom: You copy derrick-app instead of 12345678.

Impact: Your integrations don’t work. LinkedIn APIs expect a numeric identifier, not an alphabetic string.

Solution: Always verify that the Company ID is a string of 5 to 9 digits. If you see letters or hyphens, it’s a vanity URL. Use Methods 2 or 3 to get the real numeric Company ID.

Mistake 2: Using an outdated Company ID after an acquisition

Symptom: The company you’re targeting was acquired, and its old LinkedIn page merged with the parent company’s page.

Impact: The Company ID you’re using no longer returns the correct page, or redirects to an inactive page.

Solution: Before launching a campaign on hundreds of Company IDs, verify a sample by opening the URLs linkedin.com/company/[ID]/ in your browser. If you notice redirects or empty pages, update your data.

Mistake 3: Confusing Company ID and Company Page ID (for advertising)

Symptom: You try to use the Company ID in LinkedIn Campaign Manager to target audiences, but it doesn’t work.

Impact: Your advertising campaigns don’t launch correctly.

Solution: For LinkedIn Ads, you sometimes need to use the Company Page ID (or URN), which is different from the public Company ID. Consult LinkedIn Ads documentation or use the LinkedIn Marketing API to get the correct identifier. Generally, the standard Company ID works for Sales Navigator and third-party integrations, but not always for advanced advertising campaigns.

Mistake 4: Not validating Company IDs before a bulk campaign

Symptom: You launch a scrape on 500 Company IDs without verifying they’re valid.

Impact: 20-30% of IDs return non-existent pages or redirect to other pages, polluting your results.

Solution: Before launching bulk extraction, test on a sample of 20-30 Company IDs. Verify that the pages exist and correctly match the targeted companies. Derrick and other enrichment tools can automatically validate Company IDs before launching the complete workflow.

Mistake 5: Forgetting to respect LinkedIn usage limits

Symptom: You massively scrape Company IDs and profiles, and your LinkedIn account is temporarily restricted or banned.

Impact: You lose access to your account for several days, or even permanently in case of repeat violations.

Solution: Use tools that respect LinkedIn limits (rate limiting, random delays between actions). Derrick, for example, implements security mechanisms to avoid triggering LinkedIn’s anti-bot systems. Never use aggressive scrapers that send hundreds of requests per minute.

FAQ

What’s the difference between LinkedIn Company ID and vanity URL?

The Company ID is a permanent numeric identifier (e.g., 1234567), while the vanity URL is a customizable name chosen by the company (e.g., derrick-app). The Company ID never changes, even if the custom URL is modified.

Does the LinkedIn Company ID change if the company changes its name?

No, the Company ID is permanent and never changes, even in case of name change, merger, or acquisition. This stability makes it a reliable identifier for your databases and integrations.

Can you find a company’s Company ID without a LinkedIn account?

Yes, LinkedIn company pages are public. You can access any company page and see its URL (thus its Company ID) without being logged into LinkedIn.

How do you find Company IDs for multiple companies at once?

Use an enrichment tool like Derrick that can process lists in bulk. You provide a column with company names or emails, and Derrick automatically enriches each row with the corresponding Company ID.

Does the Company ID work for all LinkedIn pages?

The Company ID exists only for company pages (Company Pages), not for personal profiles. If you’re targeting individuals, use the LinkedIn Profile URL or Member ID.

Is it legal to extract LinkedIn data with the Company ID?

Extracting public data from LinkedIn is a complex subject. Always use tools that respect LinkedIn’s terms of service and GDPR regulations. Derrick implements rate limiting and compliance mechanisms to minimize risks. Always consult LinkedIn’s terms of service and, if necessary, a legal advisor before launching bulk extractions.
