TL;DR: To add a certificate to LinkedIn, open your profile, click Add profile section, choose Recommended and then Add licenses & certifications, fill in the form and click Save. The Credential ID is the unique reference your issuer gave the certificate, and the Credential URL is the web address where anyone can open the certificate and check it. Everything else in a LinkedIn certificate entry is typed in by the profile owner, so a Credential URL that opens a verifiable certificate is the one part a recruiter can confirm with a click. Dale Carnegie Sweden issues its certificates through TRUE Original, and each Credential URL opens the certificate on a subdomain that shows it comes from Dale Carnegie, where it cannot be altered.
You add a certificate to LinkedIn from your own profile: click Add profile section, choose Recommended, then Add licenses & certifications, fill in the pop-up form and click Save. LinkedIn lists Licenses & certifications among the Recommended sections in its help article on adding sections to your profile. Open the certificate in another tab first. The form asks for its link.
Take care in the Issuing organization field. LinkedIn suggests organisations from a list as you type, and its help centre advises picking the right one so that the issuer's logo appears next to the certificate on your profile.
The mobile app follows the same route. Tap your profile picture, tap it again to open your profile, then tap Add section, Recommended and Add licenses and certifications. Fill in the details and tap Save.
In the Name field, use the exact title printed on the certificate, for example "Fire Safety Training, Level 2". Anyone who compares your profile with the certificate should read the same words in both places.
Adding credentials to your Licenses & Certifications section and sharing posts is available on all LinkedIn account types, including free accounts.
A credential ID on LinkedIn is the unique reference number or code that the issuing organisation gave your certificate. A credential URL on LinkedIn is the web address of the page where that certificate can be opened and checked. Both fields sit in the Licenses & certifications form. The URL is the one a reader can click. For a TRUE Original certificate, TRUE Verify accepts either the credential ID or the Credential URL and returns a security level in seconds, free and without an account.
LinkedIn's own Add to Profile page for certification providers listed the two fields side by side: a Certificate ID with the example 1234, and a Credential URL with the example of a link ending in the same number. The ID names the certificate. The URL shows it. On the profile, LinkedIn turns the Credential URL into a Show credential button on the certificate entry, and that button is what a recruiter clicks.
Look on the certificate itself or in the email that delivered it. A TRUE Original certificate carries a unique ID, and TRUE Verify accepts either that ID or the certificate's link. No ID? Leave the field empty and fill in the Credential URL.
Paste the link that opens your certificate, not the course page or the issuer's homepage. Then test it. Open the link in a private browser window: if you see your name, the certificate and a way to check it, the link is right.
Certification URL is another name for the same thing: the web address of a certificate's own page. Some issuers call it a verification link or a share link. On LinkedIn the field is labelled Credential URL.
The credential URL matters because it is the only part of a LinkedIn certificate entry that someone other than the profile owner can check. The name, the issuer and the dates are typed in by the member. A link that opens a verifiable certificate lets a recruiter confirm it in seconds, without writing to the issuer.
LinkedIn has made the typing explicit. Its help centre says that the Add to Profile button course providers put in their emails "will no longer autofill and members must enter the relevant information directly on their profile" (LinkedIn Help, Add to Profile FAQ). LinkedIn counts more than 1.3 billion members on its pressroom statistics page in 2026. Every certificate entry among them is self-reported text until somebody clicks the link. Recruiters increasingly search LinkedIn for specific certifications and skills.
What the link opens decides what the click proves. A PDF opens a file, and a PDF can be edited. A screenshot proves less. A certificate page on the issuer's own domain, secured on a blockchain, shows that this organisation issued this certificate to this person and that nobody has changed it since.
A recruiter who clicks a TRUE Original certificate link lands on the certificate's own page on the issuing organisation's domain, sees the certificate in the issuer's design, and can confirm that it is genuine and unaltered against its blockchain record. Nobody needs an account or a phone call. The same check works through the certificate's QR code or through TRUE Verify, where anyone can paste a certificate link or ID.
Compare that with a PDF link. The recruiter downloads a file, looks at a picture of a certificate and has no way of knowing whether someone edited it last night. The signs to look for on any certificate, TRUE or not, are set out in how to check if a certificate is real.
To share a certificate as a LinkedIn post, open the certificate's own link, use its LinkedIn share button or paste the link into a new post, write a caption and tag the issuing organisation. A post reaches your network's feed once. The Licenses & certifications entry stays on your profile. Do both.
You finished the course. You passed the exam. If the certificate stays in your inbox, nobody knows. When the post links to a certificate page, LinkedIn shows a preview of the certificate in the feed, in the issuer's design, instead of a line of text.
A certificate post reaches the most people when it goes out soon after the certificate arrives, carries a caption with something specific in it, and tags the issuer so their followers see it too. Dale Carnegie Sweden, which issues its certificates through TRUE Original, reports in its 2026 case study that participants often share them within hours of receiving them.
Share your certificate within 24 to 48 hours of receiving it. LinkedIn's algorithm favours fresh, engagement-worthy content. A week later it reads as an old update.
"Proud to announce" tells your network nothing. Say what you learned, what was hard about it, and where you will put it to work. One concrete sentence about the course does more than three lines of thanks.
When you tag the organisation that issued your certificate, your post appears to their followers too. This can dramatically extend your reach, especially if the issuer has a strong LinkedIn presence.
LinkedIn's Featured section takes posts, articles, links and documents, and it displays up to 400 items, according to LinkedIn's Featured section FAQ. Pin your most important certificates here for permanent visibility, recruiters check this section. Only signed-in LinkedIn members can see the Featured section.
For a certification that defines your work, put it in your headline, for example "Certified Project Manager | Blockchain-verified credential". The headline travels with your name everywhere on LinkedIn. It's a differentiator that catches attention in search results.
TRUE Original, Credly, Accredible, Certifier and Sertifier all issue verifiable certificates that recipients can share on LinkedIn, according to each vendor's own website on 1 October 2026. They differ in where the link leads. A TRUE Original certificate opens on the issuer's own domain and is anchored on a public blockchain, so every click lands on the issuer's website and anyone can check the certificate in TRUE Verify. Dale Carnegie Sweden has issued over a thousand certificates this way, and they have been viewed tens of thousands of times.
TRUE Original certificates are built for LinkedIn because each one is a web page with its own link, secured on a blockchain and hosted on the issuing organisation's own domain. That gives the Credential URL field something worth pointing to. A PDF has no link to paste. A screenshot has nothing to check.
You can add any credential with a URL to LinkedIn. However, not all platforms generate rich link previews or offer instant verification.
A TRUE certificate is a web page with its own address. Pasted into a post, the link produces a preview with the certificate's design. Pasted into the Credential URL field, it opens the certificate itself.
Every TRUE certificate is secured on a blockchain (Ethereum, AVAX, Fantom or Polygon), so it cannot be altered after it is issued. Anyone can check it in seconds, by QR code or through the verification portal.
TRUE certificates carry the issuer's design, colours and logo, and they can be animated. On LinkedIn, this visual quality drives significantly higher engagement than a flat image or PDF screenshot.
The link points to the issuing organisation's domain, not to trueoriginal.com or a third-party platform. A recruiter sees the issuer's name in the address bar, and every click from LinkedIn lands on the issuer's website. TRUE describes the setup in its guide to custom domain certificates.
Here is an advantage that often gets overlooked: when TRUE credentials live on your domain, Google indexes them as pages on your website.
Every certificate you issue creates a new indexed page with internal links back to your main site, building your domain authority and improving your overall search ranking. Issue 500 certificates and you have 500 new indexed pages. Issue 5,000 and you have 5,000.
Platforms that host credentials on their own domain (the industry default) capture all of this SEO value for themselves. Your certificates, your content, indexed on their domain. TRUE is the opposite: the SEO benefit flows entirely to you.
The link works forever. It doesn't expire, it doesn't break, it doesn't depend on anyone keeping a server running. A TRUE certificate stays verifiable by anyone, at any time, because its record on the blockchain cannot be changed. Share it today, and it's still verifiable in 10 years.
For an issuing organisation, every certificate that a participant adds to LinkedIn puts the organisation's name, logo and link in front of that participant's network, at no cost per view. TRUE Original has issued more than 900,000 documents, and they have generated over 100 million marketing impressions worldwide. TRUE shows the arithmetic in your certificate is a marketing channel.
LinkedIn offers issuers one tool of its own. Any company or school with a LinkedIn Page can create an Add to Profile button for free, in 19 languages and with no approval process, according to LinkedIn's Add to Profile FAQ. The button no longer fills in the form, so the certificate link your participants paste is what carries the proof.
"A clear advantage of our new digital certificates is how easily they can be added as a reference to LinkedIn or a digital CV. The ease of use and verifiability creates trust!"
Lina Fjäll, Chief Customer Officer, Astrakan
"Our alumni now have nice looking Diplomas in an accessible format, but we also see great marketing value!"
Sissel Gade, Head of Operations, AW Academy
"Our customers invest in themselves, and we want that investment to be visible, lasting and easy to share."
Berit Fridman, CEO, Dale Carnegie Training Sweden
TRUE has generated over 100 million marketing impressions and €9.5 million+ in calculated marketing value for issuers, largely driven by LinkedIn sharing. TRUE's analytics show an issuer when, where and by whom each certificate is opened and shared. Before a participant can add a certificate to LinkedIn, the issuer needs a platform that produces one with its own link, and TRUE compares the options in the best digital credential platforms for 2026. To see what TRUE would create for your organisation, book a free demo.
Dale Carnegie Sweden has issued over a thousand credentials through TRUE, and according to its 2026 case study they have been viewed tens of thousands of times.
A credential ID on LinkedIn is the unique reference number or code that the issuing organisation gave your certificate. You enter it in the Credential ID field of the Licenses & certifications form, and you can leave the field empty if your certificate has no ID.
A credential URL on LinkedIn is the web address of the page where your certificate can be opened and checked. Paste the link that opens the certificate itself, not the course page, so that anyone reading your profile can confirm it with one click.
In the LinkedIn mobile app, tap your profile picture, tap it again to open your profile, then tap Add section, Recommended and Add licenses and certifications. Fill in the details and tap Save.
You can still add a certificate without a URL to LinkedIn, but nobody reading your profile can check it. Ask the issuing organisation whether it offers a digital certificate with its own verification link.
Click the certificate's credential URL and look at where it leads: the page should sit on the issuing organisation's own domain and offer a way to verify the certificate. You can also paste the link or the credential ID into TRUE Verify at trueoriginal.com/verify, which needs no account and answers in seconds.
No. LinkedIn's Add to Profile button no longer fills in the form, so participants enter the details themselves, although the button stays free for any company or school with a LinkedIn Page. What the issuer controls is the certificate link that participants paste into the Credential URL field.
