    LinkedIn Company List Template (Free CSV)

    LinkedIn's company list template, with the exact headers Campaign Manager expects. Download it, fill it in, upload it.

    Or skip the spreadsheet faff. Drop your CRM export into the converter below and get a file LinkedIn will actually accept.

    Runs in your browser. Your list never touches our servers.

    The exact headers (copy them if you're building your own):

    companyname,companywebsite,companyemaildomain,linkedincompanypageurl,stocksymbol,industry,city,state,companycountry,zipcode

    Some templates floating around use the wrong headers. LinkedIn rejects any file where the headers have been changed or removed. These match LinkedIn's own file exactly.

    Column by column

    What goes in each column

    HeaderWhat goes in itThe mistake people make
    companynameThe name as it appears on their LinkedIn PageUsing the legal name from Companies House
    companywebsiteTheir main websitePasting a deep link to a product page
    companyemaildomainThe domain their staff email fromLeaving it blank when you've got the website
    linkedincompanypageurlhttps://www.linkedin.com/company/acme/A personal profile URL, or a number instead of the name
    stocksymbolTicker, if they're listedGuessing it
    industryTheir industryMaking one up. Leave it blank if unsure
    city, state, companycountry, zipcodeHQ location. Country as a two-letter code (GB, US)Writing "UK". It's GB

    You only need one of name, website, email domain, Page URL or stock symbol per row. But every extra column you fill gives LinkedIn more to match on. Blanks are fine.

    My take

    James Green, Evergreen

    Company lists are the best targeting LinkedIn has.

    Upload the accounts you want. Then layer the job titles that actually sign contracts. You reach the whole buying committee, not just the one person who happens to be in your CRM.

    The column everyone skips is the LinkedIn Page URL. It's the most reliable identifier you've got. If all you've got is company names, expect a fight.

    Troubleshooting

    6 reasons your company list won't match

    1. A person, not a company.linkedin.com/in/... in the Page URL column. LinkedIn wants /company/. The converter catches these.

    2. Numbers instead of names./company/1234567/ works worse than /company/acme/. LinkedIn says so itself.

    3. Names only."Acme" matches a dozen Acmes.

    4. The parent, not the subsidiary.If you sell to the UK arm, upload the UK arm.

    5. Stale data.Acquired, renamed, rebranded, gone.

    6. Too few rows.300 is the floor to upload. Not everything matches, so aim for 1,000+.

    The bit LinkedIn doesn't make obvious

    Your audience expires if it isn't used in an active or draft ad set for 90 days. Draft counts. Park a draft ad set on your best lists and they stay alive.

    Questions

    FAQ

    What columns does a LinkedIn company list need?

    Ten headers: companyname, companywebsite, companyemaildomain, linkedincompanypageurl, stocksymbol, industry, city, state, companycountry, zipcode. Don't rename, reorder or delete them. Leave cells blank if you don't have the data.

    What's the minimum for a LinkedIn company list?

    Two minimums. Your file needs at least 300 rows to upload. Then the matched audience needs at least 300 LinkedIn members before an ad set can use it. LinkedIn recommends 1,000+ companies.

    Which column matters most for matching?

    The LinkedIn Page URL, using the company name version, not the number. Then website or email domain. Company name on its own is the weakest.

    How long does LinkedIn take to process a company list?

    Up to 48 hours, occasionally longer. The audience shows as "< 300 members" and greyed out if it hasn't hit the minimum.

    Do LinkedIn company lists expire?

    Yes, if they're not used in an active or draft ad set within 90 days.

    Can I combine a company list with job titles?

    Yes, and you should. Add the list to your audience, then narrow by job title, function or seniority.

    Is this LinkedIn's official template?

    It uses the exact headers from LinkedIn's own downloadable template, checked on 12 October 2026. We're an independent agency, not affiliated with LinkedIn.

    List sorted. Now the hard bit.

    Uploading is easy. Turning a list into meetings is where most campaigns fall over: the wrong job titles layered on, boring ads, budget spread too thin.

    That's the bit we do for niche B2B firms.
